KH550改性氧化石墨烯/聚苯乙烯磺酸钠及其与丁苯橡胶的复合材料性能研究

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。;Under the physical modification of interface agent polystyrene sulfonate sodium （PSS），the graphene oxide （GO） was chemically modified by silane coupling agent KH550（KH550-forshort） to obtain 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 interface agent PSS .Compared with the composite without KH550-GO/PSS，the physical properties and airtight property of KH550-GO/PSS/SBR composites improved
