| 中文摘要: |
| 采用2-巯基苯并咪唑（防老剂MB，以下简称MB）对GO进行还原及功能化，同时与采用抗坏血酸（VC）对GO进行还原以比，分别制得MB还原氧化石墨烯（rGO-MB）和VC还原氧化石墨烯（rGO-VC），并采用胶乳共混法制备rGO-MB/NR和rGO-VC/NR复合材料，对其性能进行研究。结果表明：MB成功还原了GO，MB接枝到了GO上；与rGO-VC/NR复合材料相比，rGO-MB/NR复合材料具有较低的Panye效应和较高的结合胶含量，拉伸强度和导热性能均明显提高。 |
| 英文摘要: |
| In this study，graphene oxide （GO）was reduced and functionalized by using 2-
mercaptobenzimidazole（antioxidant MB，hereinafter referred to as MB）and ascorbic acid（VC），respectively.
Natural rubber （NR） composites filled with MB reduced graphene oxide （rGO-MB） and VC reduced
graphene oxide （rGO-VC） were prepared by latex blending method，and their properties were studied.
The results showed that，GO was successfully reduced and grafted by MB. Compared with rGO-VC/
NR composites，rGO-MB/NR composites had lower Payne effect，higher content of bound rubber，and
significantly improved tensile strength and thermal conductivity. |
