Thermal and electrical analysis of vapor grown carbon nanofiber/ polyoxymethylene (VGCNF/POM) composites

Vapor grown carbon nanofiber (VGCNF) reinforced polyoxymethylene (POM) composites were studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The electrical resistivity was also analyzed.The thermal stability of the composites was affected by VGCNFs. A drop of 14 orders of magnitude of volume resistivity was obtained by inclusion of 5 wt% VGCNFs. VGCNFs were shown to act as defects, the crystallinity was lowered and the crystallization was delayed.
