Abstract

This work investigated the effects of levels of silica content, silica nano-particle size and heat treatment temperature
on the contact angle of TEOS-SiO₂
-PDMS films. Design-Expert^® software was used to design the experiments and analyze
experimental results. The results indicate that both silica amount and heat treatment have significant effects on the contact
angle of TEOS-SiO₂
-PMDS films, while silica particle size and interactions between factors have no important effect.
