Abstract

The effect of cross-link switching on the pullout of carbon nanotube (CNT) from amorphous polymer was investigated. The CNT was modeled as a graphite tube consisting of C atoms. The amorphous polymer chains were modeled by the united-atom model, which treats a CH2 methylene group as a single united atom. The pull-out simulation was conducted with and without cross-links in the interface. The axial length of the matrix was 6.0 nm and the model's cross-sectional area was 4.0 × 4.0 nm2. The chains were successfully created until the PE density reached 1.0 g/cm2. The result presents the molecular dynamics simulation for the CNT-polymer system without cross-links and with two, four, and six cross-links. The chemical bond between the CNT and the polymer significantly increases the resistible surface pressure. Also the interfacial strength can be achieved the density of the cross-link per CNT atom reaches about 0.5 to 1%.
