Abstract

Copolymer films of acrylic acid butyl ether and styrene modified with graphene oxide (GO) (0.1–2.0 wt %) with different average lateral sizes of nanosheets (25 and 250 µm) are obtained by simply mixing aqueous dispersions. The films are characterized using Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). Water absorption is also measured for the films and mechanical tests (tensile strength) are performed. It is shown that small additives of GO act as a coalescent and increase the thermal stability and Young’s modulus of films. It is established that films modified with GO with a larger nanosheet area have higher mechanical characteristics.
