改性石墨烯/丁腈橡胶纳米复合材料的制备及性能研究
|
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. 0×10-7S/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. 2×10-12S/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. 6×10-8S/m,比纯的NBR增加了7个数量级,基本满足抗静电要求。
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. 0×10-7 S/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.
