Abstract

Ethylene vinyl alcohol (EVOH) copolymer is of semi crystalline materials with excellent barrier properties to gases. Also, it has shown outstanding chemical resistance. Despite its low gas permeability, EVOH copolymer displays poor water and water vapor resistance. In this study, Trimethoxymethylsilane (as hydrophobic coating) was deposited by Plasma Enhanced Chemical Vapor (PECVD) method on the coated paper with Ethylene vinyl alcohol in order to improve the paper's barrier properties of moisture transmission. Coating by PECVD method was done in the certain conditions of time 6 min and pressure 300 m Torr. Different treatments were applied for power including 50, 70 and 90W.Then contact angle was measured in order to determined improvement of the paper's barrier properties of moisture transmission . The result showed that papers which were coated with Trimethoxymethylsilane had higher contact angle water 55.7% more than the control. The results revealed that the best condition was obtained by 50 W power. The structural and chemical properties of deposited layer were observed with Fourier Transform infrared spectroscopy- Attenuated Total Reflectance (FTIR-ATR) and Energy Dispersive X-ray Spectroscopy (EDS). The results confirmed bonding of silane on the surface EVOH polymer.
