The influence of plasma treatment by plasma activation equipment on the piezoresistive characteristics of carbon black/silicone rubber

The influence of plasma treatment by plasma activation equipment on the piezoresistive characteristics of carbon black/silicone rubber

The influence of plasma treatment by plasma activation equipment on the piezoresistive characteristics of carbon black/silicone rubber: Carbon black/silicone rubber is a good material for manufacturing flexible sensors due to its piezoresistive effect and good flexibility. However, this type of material has a small range of resistance change, poor sensitivity to pressure signals, and carbon black is easy to prepare in the preparation. Agglomeration makes it unevenly dispersed in the rubber and affects the stability of the piezoresistive performance. 　　 Add nano Al2O3 particles to carbon black/silicone rubber to improve the stability of the material's electrical properties and maintain good flexibility, and also increase the pressure sensitivity range of the material. Mixing the non-fused base materials polypropylene and polystyrene to control the carbon black particles to be selectively located at the interface of the two bases to form a rod-like structure, so that the carbon black forms a stable and uniform conductive network, and improves the piezoresistive properties of the material . 　　The carbon blacks of different particle sizes were mixed, and it was found that the carbon black with a certain distribution of particle size and specific surface area in the material has better conductivity and dispersibility than the single-distributed carbon black. The carbon black is treated with a coupling agent to improve its dispersibility in the epoxy resin and improve the conductivity of the material. 　　 The above-mentioned methods all change the original two-phase structure of the material, and at the same time have a certain influence on the flexibility of the material. Plasma treatment by plasma activation equipment can not only change the surface chemical properties of carbon materials, but also control the surface physical properties of the materials. Compared with the sample without plasma treatment, the resistance of the sample made of carbon black after plasma treatment by plasma activation equipment is reduced, while the resistance of the treated sample is significantly increased, and the resistance range is greatly changed. improve. The plasma-treated carbon black samples have higher pressure sensitivity. 　　 When carbon black/silicone rubber is deformed by external pressure, friction will be generated between the macromolecular chains of silicone rubber. At the same time, friction will also be generated between silicone rubber molecules and carbon black molecules. After 　　 carbon black is treated with plasma, the piezoresistive performance of the sample has obvious changes, and different plasmas significantly affect the piezoresistive performance of the sample. In addition, plasma treatment improves the pressure sensitivity of the sample. 　　 argon plasma activation equipment plasma treatment removes part of the oxygen-containing impurities on the surface of carbon black and introduces nitrogen-containing functional groups. Its effect is similar to that of oxygen-containing functional groups. It acts as an electron trap and causes the resistance of carbon black to increase. Argon is an inert gas. After argon plasma treatment, the impurities, functional groups and unstable boundary layers that trap electrons on the carbon black surface are removed, the conductivity of the carbon black is improved, and the resistance is reduced. Plasma treatment increases the specific surface area of ​​carbon black. When carbon black/silicone rubber is pressed, the probability of contact between carbon black particles is greatly increased, which makes the resistance change of the sample more obvious and is more sensitive to pressure sex. 　　Plasma treatment improves the pressure sensitivity of carbon black/silicone rubber. After plasma treatment by plasma activation equipment, the carbon black is more uniformly dispersed in the silicone rubber matrix and the particle size is smaller; the etching effect of the plasma on the carbon black increases the contact probability between the carbon black during the pressure process, and it is easy to form electrical conductivity aisle.

Plasma processing equipment manufacturers introduce the characteristics of key-operated plasma processing equipment

Plasma processing equipment manufacturers introduce the characteristics of key-operated plasma processing equipment

Plasma processing equipment manufacturers introduce the characteristics of key-operated plasma processing equipment: Key-press operation is actually an operation method of plasma processing equipment, which is also called manual operation. What are the characteristics of this operation method and what it generally contains, the plasma processing equipment manufacturer will introduce you to you below. At present, in the operation and control of plasma processing equipment, key operations and touch screen operations are common, and key operations are generally performed on small experimental equipment. Since PLC has never appeared and has never been used, almost all control systems are controlled by relays. This control method includes button and contact control. Push-button control mode means that the circuit of electric equipment is controlled by a manual controller; contact control mode is logically controlled by a relay, and its control object is both electric equipment and the relay's own coil. Relay control refers to the series and parallel connection of mechanical contact parts of electrical components to form a logic control circuit. Small-scale experimental low-pressure plasma processing equipment mostly adopts button control; the main electrical components controlled are: vacuum pump, RF power supply, buzzer with light, vacuum gauge, timer, float flowmeter, power regulator, green power supply indicator Lamp, self-locking vent button, self-locking gas one button, self-locking gas two buttons, self-locking high-frequency power button, self-locking vacuum pump self-locking button and total power knob switch. The disadvantages of this kind of small experimental plasma processing equipment are: because its contacts are connected by wires, it is more prone to failure, low reliability, and difficult to maintain. The relay components are all discrete components, which are large in size and inconvenient. Realize more complex logic control; its advantage is that the price is relatively cheap, the control objects can be one-to-one correspondence, the equipment operation is more intuitive, and the operation is more flexible. The above are the main control appliances and their advantages and disadvantages of the button-type small experimental low-voltage plasma treatment equipment.

Chengfeng Zhizhi plasma cleaning machine manufacturer explains the role of silicon wafers in the manufacture of silicon cells: Common lithium batteries should be considered lithium-ion batteries. Portable electronic products such as laptop computers, video cameras, and mobile communications are widely used in our daily lives. Now it is also developing silicon batteries, which are expected to be applied to mobile phone batteries. The following is a detailed explanation of the plasma cleaning machine manufacturer made by Chengfeng Zhizhi. Nowadays, the smartphones in our hands are basically lithium batteries, and battery technology is also one of the difficulties in today's smart technology demand breakthrough. According to foreign media reports, a startup company called XNRGI wants to break this situation and plans to release it next year. It produces a higher energy density, lower manufacturing cost, and safer use than traditional lithium-ion batteries. In addition, the company uses a method similar to that used by semiconductor companies to manufacture processors, using wafers to make silicon cells. At present, the plasma cleaning machine manufactured by Chengfeng Zhizhi is mainly used for the cleaning of silicon wafers and the removal of photoresist. Therefore, people are also very interested in this method of using silicon wafers to manufacture batteries. At present, XNRGI has been researching and developing silicon batteries for 15 years. Its energy density is 4 times that of lithium batteries, and its cost is only half of that of lithium batteries, and its "porous" silicon batteries can be used in many scenarios, such as Many smart terminals such as smart phones. The manufacturing principle of this battery is to etch very fine 20×20 micron honeycomb images on these wafers, and then coat them with lithium and other metals to form the anode and cathode of the so-called "microbattery", that is, every 12 An inch silicon wafer contains 36 million such vertical micro-cells (with an energy density of more than 400Wh/kg), which constitute a macro battery. Because of this unorthodox structure, charging is faster. XNRGI's batteries are recyclable, unlike traditional lithium-ion batteries that are as easily thermally out of control. Their energy density exceeds 400Wh/kg, which makes them cheaper to manufacture, so they are very suitable for storing electric vehicles and grids.
