The manufacturing process of thermoregulation products with polyester (PES) fabric and conductive polymers such as poly(3,4-ethylenedioxythiophene) doped with poly(styrene sulfonate) (PEDOT:PSS) with proper wearability, comfort, and high performance is still a challenge due to low adhesion, environment instability and non-uniform coatings. This study presents a simple and effective method for producing thermoregulatory PES fabrics using the Joule heating effect. Textiles treated with dielectric barrier discharge (DBD) plasma were functionalized with PEDOT:PSS incorporating secondary dopants, such as dimethyl sulfoxide (DMSO) and glycerol (GLY). PEDOT:PSS was used because it does not compromise the mechanical properties of base materials. DBD plasma treatment was applied to PES to improve the substrate’s functional groups and consequently increase adhesion and homogeneity of the PEDOT:PSS on the substrate. The polymer were applied to the textiles by dip-pad-dry-cure method ensuring uniform distribution and homogeneous heating of the materials. The samples’ conductivity, impedance, potential and Joule effect, and their morphological, chemical and thermal properties were studied. Control samples without plasma treatment and secondary dopants were also prepared. The results showed that the DBD-treated samples, coated with 5 layers of PEDOT:PSS, doped with DMSO 7 % (w/v), displayed the best conductivity and Joule effect performance reaching 44.3 °C after 1 h.

DBD 等离子体处理的聚酯织物，涂有掺杂 PEDOT：PSS，用于体温调节


聚酯 （PES） 织物和导电聚合物（如掺杂聚苯乙烯磺酸盐）（PEDOT：PSS）的聚（3,4-乙烯二氧噻吩）掺杂聚苯乙烯磺酸盐 （PEDOT：PSS））的体温调节产品的制造过程由于附着力低、环境不稳定和涂层不均匀，仍然是一个挑战。本研究提出了一种利用焦耳热效应生产温度调节 PES 织物的简单有效的方法。用介电势垒放电 （DBD） 等离子体处理的纺织品用 PEDOT：PSS 进行功能化，其中加入了二次掺杂剂，例如二甲基亚砜 （DMSO） 和甘油 （GLY）。使用 PEDOT：PSS 是因为它不会影响基材的机械性能。对 PES 进行 DBD 等离子体处理以改善基材的官能团，从而提高 PEDOT：PSS 在基材上的粘附力和均匀性。聚合物通过浸渍-垫-干固化方法涂覆到纺织品上，确保材料的均匀分布和均匀加热。研究了样品的电导率、阻抗、电位和焦耳效应，以及它们的形态、化学和热学性质。还制备了未进行等离子体处理的对照样品和二次掺杂剂。结果表明，涂覆 5 层 PEDOT：PSS、掺杂 7 % （w/v） 的 DBD 处理样品表现出最佳的电导率和焦耳效应性能，1 h 后达到 44.3 °C。
