Study on Graphene Oxide Modified Polyvinylbutyral Transparent Polymer Films
Different ionic surfactants were applied in this work to modify graphene oxide(GO).Then,a series of functionalized-graphene-oxide@polyvinylbutyral(PVB/f-GO)composites were prepared via the solution blending method.The X-ray diffractometer(XRD),atomic force microscopy(AFM)and transmission electron microscopy(TEM)analyses revealed that the surfactant insertion effectively prevented the aggregation of GO and improved its dispersibility in PVB.The mechanical and optical measurements showed that when 0.02 wt％sodium hexadecyl sulfonate modified graphene oxide(s-GO)was added,the tensile strength of PVB/f-GO composite material was 38.1％higher than that of pristine PVB,while the visible light transmittance was maintained at 88％.When the sodium hexadecylbenzene sulfonate modified graphene oxide(sd-GO)content was 0.03 wt％,the tensile strength of PVB/sd-GO composite materials was increased by 28.4％compared to that of pristine PVB,while the ultraviolet shielding ability was increased above 65％.
