Abstract
pCBT/MWCNT nanocomposites were prepared by in situ polymerization of CBT after solid‐phase HEBM of the polymerization catalyst containing CBT with MWCNT. The crystallinity and crystallization behavior of the pCBT nanocomposites were studied by WAXS and DSC. The MWCNTs did not affect the crystallinity of the isothermally produced pCBT significantly, but acted as nucleation agents during the crystallization of pCBT from its melt. pCBT/MWCNT nanocomposites were subjected to DMTA, static flexure, and dynamic Charpy impact tests. The flexural modulus, strength, and impact strength from these tests all went through a maximum as a function of the MWCNT content. Optimum properties were found in the MWCNT range of 0.25–0.5 wt.‐%. magnified image
