摘要
摘译目前,含有导电聚合物的涂布纸在新型功能纸及其包装应用方面引起了极大的关注,如防静电和电磁屏蔽纸、墙纸以及抗菌纸。在用于包覆纤维的导电聚合物中,聚吡咯(PPy)由于具有低毒性、化学稳定性和商业可用性而成为一种优选的导电聚合物。此外,聚苯胺(PANi)作为另一类导电聚合物,由于具有高度p-共轭聚合物链、导电性、掺杂/脱掺杂过程中可逆的化学性能、不同的形貌、电化学性能和物理性能等特点,
Conducting paper based on natural cellulosic fibers and conductive polymers was prepared using unbleached ba- gasse and/or rice straw fibers (as cellulosic raw materials) and polyaniline (PANi) as conducting polymer. These compos- ites were synthesized by in situ emulsion polymerization using ammonium persulfate (APS) as oxidant in the presence of do- decylbenzene sulfonic acid (DBSA) as emulsifier. The prepared composites were characterized using Fourier transform infra- red (FTIR), thermal gravimetric analysis (TGA), differential scanning calorimeter (DSC), and their morphology was in- vestigated using scanning electron microscope (SEM). Electrical conductivity measurements showed that the conductivity of the paper sheets increases by increasing the ratio of PANi in the composite. Mechanical properties of the paper sheets were also investigated, the results revealed that the values of breaking length, burst factor, and tear factor are decreased with in- creasing ratio of added PANi, and this effect is more pronounced in bagasse -based composites. The new conductive com- posites can have potential use as anti - static packaging material or anti - bacterial paper for packaging applications.
