Preparation of Graphene Hybrid Material and Thermal Properties of Polymer Composites
Graphene is the most intensive material known at present, and it has great application value for the preparation of high performance polymer matrix composites. In this context, the preparation of polymer nanospheres and graphene hybrids is based on the design and low density of the polymer particles. Two polymer nanosphere/graphene hybrid fillers were designed to solve the problem of easy stacking of graphene. It is used to reinforce rubber and filler network structure evenly and effectively dispersed in rubber aggregates to prepare rubber nanocomposites with excellent comprehensive performance and light weight. X-ray diffraction (XRD), infrared spectroscopy (FTIR), Raman spectroscopy (Raman) and Thermogravimetric Analysis (TGA) study the structure of PS@rG0. The results show that rG0 is effectively reduced in hybrid materials and has a strong π-π interaction with PS, thus avoiding the re-deposition of rG0 during the reduction process; scanning electron microscopy (SEM) analysis shows that PS nanospheres are on the rGO surface. The upper adsorption acts as a barrier and the rGO layer also inhibits further aggregation of the PS.
