摘要
氧化石墨烯(GO)先用促进剂CBS改性,再用水合肼还原制备水合肼和促进剂CBS共改性GO(H-C-GO),研究绿色轮胎用功能化石墨烯/天然橡胶(NR)复合材料的性能。结果表明:水合肼和促进剂CBS共改性的H-C-GO的团聚显著减少且与橡胶之间的相容性较好;H-C-GO/NR复合材料具有比GO/NR复合材料或水合肼还原GO/NR复合材料更高的拉伸强度、更好的抗湿滑性能和更低的滚动阻力。
Graphene oxide(GO)was first modified with accelerator CBS,then reduced with hydrazine hydrate to prepare hydrazine hydrate and accelerator CBS co-modified GO(H-C-GO),and the properties of functional graphene/natural rubber(NR)composites for green tires were studied.The results showed that,H-C-GO co-modified by hydrazine hydrate and accelerator CBS could have significantly reduced agglomeration and improved compatibility with rubber,and the H-C-GO/NR composites had higher tensile strength,better wet skid resistance and lower rolling resistance than the GO/NR composites and hydrazine hydrate reduced GO/NR composites.
