Abstract：Toimprove theconductivityof polyaniline/polyester（PANI/PET）compositeconductive fabrics，diferentacid doping methods were used to regulate the molecular structure of PANI.PANI was polymerized in situ on the surface of PET fibers to prepare PANI/PETcomposite fabrics.The effect of doping acid types on the structure and conductivity of PANI/PETmaterials was analyzed using SEM，FTIR，XRD，and conductivity testing; PANI/PET composite conductive fabric wasassembled with metal Al and Cu film electrodes to prepare Schottky type nanogenerators and their electrical output performance was investigated.The results indicate that the type of doping acidsignificantlyafectsthe benzoquinone structure ratio，molecular chainregularity，and interplanarspacing of PANI; PTSA doped PANI exhibits the highestbenzene/quinone structure ratio （2.16），optimal interplanar spacing （0.343nm ），and highest crystallinity（ 46.16% ），resulting in the best conductivity performance （O.65 S/m）; The Schottky nanogenerator prepared based on PTSA doped PANI/PET composite material exhibits excellent electrical output performance，with an open circuit voltage of 0.973V and a short-circuit current of 327.19μA ， furtherverifying the excellent conductivityof the material.
