摘要/Abstract

摘要：

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。

Abstract:

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-SiO₂hybrid materials was confirmed by infrared spectroscopy. Furthermore, the mechanical properties of graphene-SiO₂hybrid 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-SiO₂hybrid 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.

Key words: polybutadiene rubber, styrene-butadiene rubber, conductive carbon black, conductivity, wear resistance, graphene loading
