New insights into interface interactions of CNT-reinforced epoxy nanocomposites

Interfacial shear strength between carbon nanotubes (CNTs) and polymer matrices is a fundamental but unresolved issue. Here, through molecular dynamics simulation (MD), we revealed that there are two completely different interfaces between CNTs and epoxy matrix, namely the weak interface (τemb) at the embedded CNT region, and the strong pull-out interface (τpull−out) occurred at the entry position of CNT. Strikingly, the load transfer capability...
