Flexible fabrics have gained widespread attention in thermal management and energy harvesting recently due to their fascinating merits of flexibility and breathability. However, the simple and efficient integration of multiple functions into a single fabric remains a challenge. Herein, a multifunctional fabric was prepared by in-situ polymerized polyaniline (PANI) and polypyrrole (PPy) onto air-laid paper (AP), followed by wrapping with hydrophobic reagent. The synergistic effect of PANI and PPy networks endowed the composite fabric with excellent photothermal performance. Additionally, the smart fabrics exhibited the terrific self-cleaning property. More promisingly, triboelectric nanogenerator (TENG) based on the smart fabrics as effective positive friction material could transform electrical signal with through collecting energy from small human movement, delivering charge of 82.7 nC, open circuit voltage of 213.6 V, and short circuit current of 14.7 μA. This work provides new insights for the study of the next generation lightweight, portable thermal management fabric.

具有出色自清洁和高光热效应的多功能复合织物用于生物机械能量收集器


柔性织物由于其柔韧性和透气性的迷人优点，近年来在热管理和能量收集领域受到广泛关注。然而，将多种功能简单有效地集成到单一结构中仍然是一个挑战。在此，通过将聚苯胺（PANI）和聚吡咯（PPy）原位聚合到无尘纸（AP）上，然后用疏水剂包裹来制备多功能织物。 PANI和PPy网络的协同作用赋予复合织物优异的光热性能。此外，智能织物还表现出出色的自清洁性能。更有前景的是，基于智能织物作为有效正摩擦材料的摩擦纳米发电机（TENG）可以通过收集人体微小运动的能量来转换电信号，提供82.7 nC的电荷、213.6 V的开路电压和14.7 V的短路电流。微安。这项工作为下一代轻质便携式热管理织物的研究提供了新的见解。
