十八胺改性氧化石墨烯/乳聚丁苯橡胶复合材料的结构与性能研究
|
摘要
以十八胺(ODA)对氧化石墨烯(GO)进行改性,采用乳液复合法制备ODA功能化GO(ODA-GO)/乳聚丁苯橡胶(ESBR)复合材料,并对其结构和性能进行研究。结果表明:ODA-GO在ESBR中的分散性良好,少量ODA-GO在ESBR中能够形成较强的填料网络;与ESBR胶料相比,ODA-GO/ESBR复合材料在0℃时的损耗因子(tanδ)增大,60℃时的tanδ减小;随着ODA-GO用量的增大,复合材料的物理性能和气密性能提高。
The graphene oxide(GO) was modified by octadecylamine(ODA),the octadecylamine functionalized graphene oxide(ODA-GO)/emulsion styrene-butadiene rubber(ESBR) composite was prepared by emulsion composite method,and its structure and properties were studied. The results showed that,the dispersion of ODA-GO in ESBR was good,and strong filler network could be formed with small amount of ODA-GO. Compared with ESBR compound,the loss factor of ODA-GO/ESBR composite increased at 0 ℃ and decreased at 60 ℃. As the addition level of ODA-GO increased,the physical properties and airtight property of the composite were improved.
