摘要选用离子液体1-烯丙基-3-甲基咪唑盐酸盐(AMI)改性氧化石墨烯(GO)得产物(AGO),采用乳液共混法制备不同AGO含量的AGO/丁苯橡胶(SBR)硫化胶。分析了AMI改性GO的机理,研究了AGO对SBR硫化胶力学性能的影响,并采用Mooney-Rivlin理论分析了AGO/SBR硫化胶的网络结构。结果表明: AMI与GO之间存在氢键与阳离子-π相互作用。当AGO含量为5 phr时,对比未填充SBR硫化胶,AGO5/SBR硫化胶的交联密度提升了110 %;应变为100 %时的拉伸模量(M100)、应变为300 %时的拉伸模量(M300)、拉伸强度和撕裂强度分别增加了95。8 %、351。9 %、504。6 %和362。0 %,并且其断裂伸长率仍能保持94 %;平衡溶剂吸附量下降幅度达31 %。而对比GO5/SBR硫化胶,AGO5/SBR硫化胶的M100、M300、拉伸强度和撕裂强度则分别提升了9。3 %、15。5 %、40。1 %和15。6 %。77141

Title The mechanical properties of ionic liquid modified graphene oxide/styrene butadiene rubber vulcanizates
Abstract In this paper, ionic liquid 1-allyl-3-methyl-imidazolium chloride (AMI) was selected as the modifier to improve the exfoliation of graphene oxide (GO)。The modified GO (AGO)/styrene butadiene rubber (SBR) vulcanizates were prepared via latex compounding。 The interaction between GO and AMI was throughoutly investigated。 The effect of AGO loading on the mechanical properties of SBR was studied。 And Mooney-Rivlin theory was utilized to analyze the network structure of AGO/SBR rubber vulcanizates。 The results showed that AMI molecules could interact with GO via the combination of strong hydrogen bond and cation-π interaction and participate the crosslinking of SBR via a reactive double bond。 The homogeneous dispersion of AGO is still maintained at loadings up to 5 phr。 Compared with virgin SBR, the crosslinking density of AGO5/SBR increased by 110 % and the the tensile modulus at 100% elongation (M100), tensile modulus at 300% elongation (M300), tensile strength and tear strength increased by 95。8 %,351。9 %,504。6 % and 362 %, respectively。 And the adsorption equilibrium solvent decreased by 31%。 Compared with GO5/SBR, the M100, M300, tensile strength and tear strength of AGO5/SBR improved by 9。3 %, 15。5 %, 40。1 % and 15。6 % respectively。
