摘要
Polyethylene terephthalate (PET) blends with a nanorod form of polyaniline (NR-PANI), formed by a falling pH synthesis, were prepared by dispersion in a melt of PET at 265 degrees C. Blends with 1, 2 and 3 wt% NR-PANI loading were prepared. Optical microscopy revealed an even distribution of NR-PANI particles within the PET matrix. The blends were characterized using FTIR, XPS, DSC and DMTA. Melt flow index values suggested hydrolysis of PET chains to lower molecular weight units when NR-PANI was blended. Some PET hydrolysis was also evident from the increasing oxygen to carbon ratios with an increased NR-PANI content in the blends. While the PET glass transition temperature remained relatively unaffected, the degree of PET crystallinity was increased with the addition of NR-PANI. The electrical conductivity as well as the free radical scavenging capacity of PET increased with greater NR-PANI loading in the matrix. The mechanical properties of PET, however, declined with NR-PANI loading suggesting a lack of adequate interfacial adhesion between the NR-PANI particles and the PET matrix. (C) 2012 Elsevier B.V.
