Incorporation of PANI with polyethylene terephthalate (PET) fibers has creates many flexible conductive, electrothermal and energy-storage textiles. The most common method of depositing PANI to PET fibers is in-situ polymerization. However, it usually needs long reaction time and strict conditions, which is unbeneficial to large-scale commercialized process. Herein, a facile and high-efficiency surface micro-dissolution method was proposed to prepare PANI-coated PET fabrics, which is performed at moderate temperature (70 °C) and only needs 15 min of treatment time. Already-made PANI powders were directly used as raw materials, and the phenol/N-methyl pyrrolidone (phenol/NMP) solution worked as the surface micro-dissolution agent. The resulting fabrics show electroconductive (620 Ω/□), electrothermal (from 22.3–30.3 ℃ within 1 min) and energy storage (438.51 m F cm⁻²) performances. The preparation is easy to perform and of very high efficiency, making it suitable for industrial production of PANI-coated PET fabrics.

PANI与聚对苯二甲酸乙二酯（PET）纤维的结合产生了许多柔软的导电，电热和储能纺织品。将PANI沉积到PET纤维上最常见的方法是原位聚合。但是，它通常需要较长的反应时间和严格的条件，这不利于大规模的商业化工艺。在此，提出了一种简便高效的表面微溶解方法来制备PANI涂层的PET织物，该方法在中等温度（70°C）下进行，仅需要15分钟的处理时间。已有的PANI粉末直接用作原料，苯酚/ N-甲基吡咯烷酮（苯酚/ NMP）溶液用作表面微溶解剂。所得织物显示出导电性（620Ω/□），电热性（1分钟内从22.3–30.3℃起）和能量存储（438.51 m F cm ^-2）性能。该制备易于进行且效率非常高，使其适合工业生产PANI涂层的PET织物。
