摘要
In this paper, we present classical molecular dynamics （MD） simulations of model polymer/CNT composites constructed by embedding a single wall （10,10） CNT into two different amorphous polymer matrices： poly（methyl methacrylate） and poly{（m-phenylene-vinylene）-co- [（2,5-dioctoxy-p-phenylene） vinylene]}, respectively, with different volume fractions. The simulation results support the idea that it is possible to use CNTs to mechanically reinforce an appropri- ate polymer matrix, especially in the longitudinal direction of the nanotube. The comparison of the simulation results with the macroscopic rule-of-mixtures for composite systems showed that for strong interfacial interactions, there can be large deviations of the results from the rule-of- mixtures. In order to verify this study, results obtained have been compared with those given by Elliott and Han （2007）.
