Characteristics of SiOx-containing hard film prepared by low temperature plasma enhanced chemical vapor deposition using hexamethyldisilazane or vinyltrimethylsilane and post oxygen plasma treatment
With increase in HMDSZ and VTMS deposition times, the film thickness increases and the refractive index decreases. The optical transmittance of PET after the VTMS treatment increases from 89% to 95%. The SiO2 films deposited by HMDSZ+O2 and VTMS+O2 plasma can increase the film hardness and improve light transmittance. It is expected that they can be applied to the optical transmittance protective film on plastic substrate in the future.
