摘要
The research initially involved the decoration of silver nanoparticles on carbon nanotubes using N,N-dimethylformamide. A new heteroaromatic azo-polymer was prepared and employed as a matrix while Ag-CNTs as filler. Two techniques were exploited to prepare nanocomposites (i.e., melt compounding and solution mixing). The solution mixing method resulted in better dispersion leading to higher mechanical strength 55.09-58.22MPa relative to melt system 40.11-46.28MPa. Filler content from 1 to 5wt% increased electrical conductivity from 3.8 to 5.2Scm(-1). 10% gravimetric loss was found to increase from 532 to 578 degrees C (solution) and 503 to 544 degrees C (melt).
