摘要
通过简单的回流氧化石墨烯(GO)和二乙基甲苯二胺(E-100)成功实现氧化石墨烯的原位功能化还原,制备了导电及表面修饰的氧化石墨烯(GO-E100),其电导率由GO的1.0×10-7 S/m提高到1 S/m。此外,制备的GO-E100有效地增强了以丁腈橡胶(NBR)为基体的柔性复合材料的力学性能和导电性能。当GO-E100在复合材料中的质量分数为4.2%时,复合材料电导率达到3.2×10-12 S/m,比纯NBR增加了3个数量级,同时拉伸强度提高了18.6%;当GO-E100在复合材料中的质量分数为6.8%时,其拉伸强度提高了12%,耐油性稍有改善,复合材料电导率达到5.6×10-8 S/m,比纯的NBR增加了7个数量级,基本满足抗静电要求。
Abstract
The reduction and functionalization of graphene oxide (GO) are realized simultaneously by simply refluxing graphene oxide (GO) with diethyltoluene diamine (E100),and GO-E100 with conductivity and surface modification is prepared.GO-E100 exhibits an electrical conductivity of 1 S/m,comparing with 1.0×10-7S/m of common GO.Benefiting from the improved compatibility and high conductivity of GO-E100,GO-E100/NBR nanocomposites behaves a 18.6% improvement in tensile strength with GO-E100 content of 4.2 wt%.When the content of GO-E100 in nanocomposites reaches 6.8 wt%,the tensile strength of GO-E100/NBR composites rises by 12%,its oil resistivity is improved a little and the electrical conductivity is 7 orders higher,which meets basically antistatic requirements.
