中文摘要: |
在界面剂聚苯乙烯磺酸钠(PSS)的物理改性作用下,以硅烷偶联剂KH550(简称KH550)对氧化石墨烯(GO)
进行化学改性,制得KH550改性GO(KH550-GO)/PSS,采用乳液法制备KH550-GO/PSS/丁苯橡胶(SBR)复合材料,并
对其结构和性能进行研究。结果表明:通过PSS的加入,使KH550-GO在SBR中的分散性得到改善;与不加KH550-GO/
PSS的复合材料相比,KH550-GO/PSS/SBR复合材料的物理性能和气密性能显著提高。 |
英文摘要: |
With the physical modification of interface agent polystyrene sulfonate sodium (PSS),the
graphene oxide (GO) was chemically modified by silane coupling agent KH550(KH550-for short),then
KH550-GO/PSS,KH550-GO/PSS/styrene-butadiene rubber(SBR) composites were prepared by emulsion composite method,and their structure and properties were studied. The results showed that,the dispersion
of KH550-GO in the SBR was good by using interface agent PSS. Compared with the composite without
KH550-GO/PSS,the physical properties and airtight property of KH550-GO/PSS/SBR composites were
improved. |
