Description

technical field [0001] The invention belongs to the technical field of conductive fabrics, in particular to a washable polyaniline / polyester composite conductive fabric and a manufacturing method thereof. Background technique [0002] Polyaniline is a conjugated conductive polymer with excellent conductivity, simple synthesis and low price, and has a very wide application prospect. In recent years, researchers have begun to study the compounding of polyaniline on fabrics to endow the fabrics with good electrical conductivity. However, polyaniline is highly polar and difficult to dissolve in common solvents, resulting in processing difficulties, which greatly limits the wide application of polyaniline. [0003] The self-assembly of polyaniline on the substrate solves the problem of polyphenylene in processing. The patent number is ZL200810202711.1 Chinese invention patent discloses "a preparation method of self-assembled multifunctional polyaniline / pure cotton composite con...
