After processing the PET film by the plastic plasma processor, observe the processing effect through the contact angle:
Polyester film PET has many excellent material properties, but due to its low surface free energy, poor wettability and viscosity, which limit the production and application of polyester film, plastic plasma processors are often used to process polyester film .
 Since the processing process of the plastic plasma processor is microscopic, the SEM scanning electron microscope and contact angle tester are usually used to observe the effect of plasma treatment, and the SEM scanning electron microscope is used to test the treatment effect of the plastic plasma processor on the PET film. Introduce you to use the contact angle tester to test the processing effect of PET film.plasma processorThe PET film is tested before processing:
Select the PET film before processing by the plastic plasma processor, measure the surface water contact angle at 6 different positions of the film, and take the average value of the surface water contact angle, and the surface water contact angle of the PET film is 80.7°, which is poor Hydrophilicity.
Measure the contact angle of the PET film after 10 seconds and 60 seconds on the plastic plasma processor:
Plasma treatment is used for 10 seconds, and then the average value of 6 points is taken to obtain a water contact angle value of 49.1°, compared with 30.9° when the treatment time is 60 seconds.
With the help of the change of contact angle, we can understand that the plastic plasma processor can effectively improve the hydrophilicity of the PET film, increase the surface energy and free energy of the material, thereby improving its performance, such as surface wettability and tackiness And printability.
