基于酸掺杂的PANI/PET材料的结构调控及其导电性
Structural control of PANI/PET materials based on acid doping and its conductivity
摘要
Abstract
To improve the conductivity of polyaniline/polyester(PANI/PET)composite conductive fabrics,different acid doping methods were used to regulate the molecular structure of PANI.PANI was polymerized in situ on the sur-face of PET fibers to prepare PANI/PET composite fabrics.The effect of doping acid types on the structure and conductivity of PANI/PET materials was analyzed using SEM,FTIR,XRD,and conductivity testing;PANI/PET composite conductive fabric was assembled with metal Al and Cu film electrodes to prepare Schottky type nano-generators and their electrical output performance was investigated.The results indicate that the type of doping acid significantly affects the benzoquinone structure ratio,molecular chain regularity,and interplanar spacing of PANI;PTSA doped PANI exhibits the highest benzene/quinone structure ratio(2.16),optimal interplanar spac-ing(0.343 nm),and highest crystallinity(46.16％),resulting in the best conductivity performance(0.65 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 0.973 V and a short-circuit current of 327.19 μA,further verifying the excellent conductivity of the material.关键词
