Mechanical and electrical properties of polyamide-6-based nanocomposites reinforced by fulleroid fillers

The effect of the fulleroid fillers (fullerene C60, mixture of C60/C70 and fulleroids soot) on mechanical, tribological, and electrical properties of the nanocomposites based on polyamide‐6 (PA6) was investigated. The nanocomposites were prepared by in situ polymerization. Both the tensile modulus and tensile strength of polymer composites were improved up to 15% with loading of 0.001–0.1 wt% of fulleroids materials. For nanocomposites with fulleroid fillers, the friction coefficients were practically two times as lower that of neat PA6. Electrical volume resistivity of composites decreases at loading of fulleroid fillers. The minimal electrical volume resistance was about 107 Ω cm at 0.1 wt% loading of fullerene soot. POLYM. ENG.
