摘要: In this paper, the dispersion of carbon nanotube (CNT) in ethylene vinyl acetate (EVA) is demonstrated to be significantly improved by addition octadecylamine (ODA)-grafted graphene oxide (GO) (GO–ODA). Compared CNT/EVA composite, resultant GO–ODA/CNT/EVA (G–CNT/EVA) composite shows simultaneous increases tensile strength, Young’s modulus and elongation at break. Notably, break G–CNT/EVA still maintains a relatively high value 1268% 2.0 wt % CNT content, which more than 1.6 times higher that (783%). This should attributed homogeneous as well strong interfacial interaction between EVA originating from solubilization effect GO–ODA. Additionally, composites exhibit superior electrical conductivity low contents but inferior contents, compared for depends on balance preservation insulating Our strategy provides new pathway prepare performance polymer with well-dispersed CNT.
