| DOR:98.1000/1735-0913.1398.34.100.66.1.9.1604 In this study, EVOH was coated on paper made of CMP pulp by extrusion method in order to improve the paper's barrier properties of oxygen transmission. Ethylene vinyl alcohol (EVOH) shows poor moisture resistance despite less gas permeability. Then, dimethoxydimethylsilane was deposited using Plasma Enhanced Chemical Vapor Deposition on EVOH film as the hydrophobic layer. A random factorial experiment was designed with three factors at three levels including time (6-8-10 min), pressure (30-0400-500 m Torr), and radio frequency power (50-70-90 W). The contact angle, oxygen transmission rate, tensile strength, and strain energy were measured to obtain the optimum condition. Expert Design method using response surface was used to optimize the condition coating Dimethoxydimethylsilane in order to improve the hydrophobic properties, reduce OTR, increase tensile strength and strain energy. Based on this method the optimum condition was suggested as: time 6 min, pressure 499.99 m Torr and power 50W.
