采用单宁酸辅助液相剥离所制备的石墨烯，获得了比普通石墨烯更好的分散性，可以达到低成本、高产量和环保的要求。用硅烷偶联剂(KH550)改性处理的SiO2和单宁酸修饰的石墨烯发生反应形成强杂化键，成功得到石墨烯-SiO2杂化材料。研究了石墨烯-SiO2杂化材料在丁苯/顺丁橡胶复合材料中的力学性能，同时还研究了将导电炭黑与石墨烯-SiO2杂化材料共混后在丁苯/顺丁橡胶复合材料中的力学性能以及导电导热性能。结果表明:加入1份石墨烯-SiO2杂化材料时，丁苯/顺丁橡胶复合材料获得了相对良好的耐磨性;如果负载超过1份，石墨烯填料之间会很容易发生再聚集，导致磨损体积相比于空白对照组有所增加;加入8份自制石墨烯时，电阻值降低至2×106 Ω，橡胶复合材料的抗静电性能得到了明显的改善。
Development of high wear resistant and electrostatic conductive graphene hybrid material/butylene/parabutylene tread rubber
In this paper,graphene prepared by liquid-phase stripping assisted by tannic acid achieved better dispersion than ordinary graphene.The new graphene can meet the requirements of low cost,high output,and environmental protection.Graphene-SiO2 hybrid materials were obtained by reacting SiO2 treated with silane coupling agent(KH550)modification and graphene modified with tannic acid to form strong hybridization bonds,and the success of obtaining graphene-SiO2 hybrid materials was confirmed by infrared spectroscopy.Furthermore,the mechanical properties of graphene-SiO2 hybrid material in styrene-butadiene/polybutadiene composites were studied.In addition,the mechanical properties and the electrical and thermal conductivity of the blend of conductive carbon black and graphene-SiO2 hybrid material in styrene-butadiene/polybutadiene composite were investigated.The results show that:at the addition of 1 part per hundred(phr)of graphene-SiO2 hybrid material,the butadiene/cis rubber composites obtained relatively good wear resistance,if the loading is more than 1 phr,the graphene fillers will easily reaggregate with each other,resulting in an increase in wear volume compared with the blank control group.Moreover,when 8 phrs of self-made graphene were added,the conductivity increased by 1 000 times,and the antistatic properties of rubber composites were considerably improved.
