Abstract

Graphene oxide (G-O)/methyl methacrylate (MMA)-butyl acrylate (BA) copolymer composites were prepared by in situ emulsion polymerization.3D micro-pyramid arrays were fabricated on the surfaces the films by roll-to-roll hot embossing.The storage modulus of the composites films were studied by rheometer.The forming ratio and average height of 3D mico-pyramid arrays on the surface of the composites films were investigated as a function of G-O content,feeding speed and temperature.The results show that the storage modulus increased with the increase of G-O contents when tested by both frequency and strain sweep.With the increase of G-O content,the forming ratio of 3D mico-pyramid arrays decreased but the average height increased.At the same applied force,increasing temperature or decreasing feeding speed all could improve the forming of 3D mico-pyramid arrays on the surface of the films.
