Abstract

In order to verify roles of interphase played in glass transition temperatures (T_gs) of carbon nanotubes reinforced epoxy resin (CNT/epoxy) composites, three types of interphase were produced between the CNTs and the cured epoxy. It was achieved by selection of pristine CNTs (p‐CNTs), amino groups grafted CNTs (NH₂‐CNTs) and hydroxyl groups grafted CNTs (OH‐CNTs) as the reinforcement, respectively. Both dynamic mechanical analysis (DMA) and molecular dynamics (MDs) simulation were conducted to study T_g of the CNT/epoxy composites. The DMA tests showed that T_g of NH₂‐CNT/epoxy composites increased, while T_g of OH‐CNT/epoxy composites decreased, compared with p‐CNT/epoxy composites. The MD simulation of the CNT/epoxy composites models explained effects of interphases on T_gs of the CNT/epoxy composites. T_g of the NH₂‐CNT/epoxy composites increased with the formation of covalent bonds between the NH₂‐CNTs and the cured epoxy. Although T_g of the OH‐CNT/epoxy composites decreased due to the weak interphase, where no such covalent bonds were formed. It can be inferred that the covalent bonds between the CNTs and the polymer matrix is beneficial to increase T_g of the CNT/polymer composites. POLYM.
