Dynamic analysis and mechanical behavior of thermally conductive adhesive reinforced with amine‐grafted multiwalled carbon nanotubes

The kinetics parameters of activation energy and the pre‐exponential factor can be calculated based on the kinetics equation and integral method. The stress–strain curves of filled materials exhibit considerable nonlinearity and nonobvious yield point, which is in contrast with that of neat epoxy and matrix resins. The neat epoxy mixing with MWCNTs gets an improvement on the toughness and cohesiveness of epoxy system. The micrograph of neat epoxy exhibits the typical smooth and brilliant surface belongs to brittle materials. The fracture process is originated from a small area in the cross‐section. Nevertheless, the fracture surface of filled materials show differential fractographical feature and rougher surface with the MWCNTs added to the epoxy matrix. POLYM.
