In recent years, polythiophene (P3HT) has become a kind of typical conjugated polymer material which is suitable to use on a large scale. However, it is difficult to obtain long P3HT fibers with a highly ordered arrangement due to the entanglement of molecular chains and inherent flexibility. In this work, P3HT fibers were successfully constructed and assembled by an electric-field-induced technique, which can be observed directly. The orientation of the P3HT molecules was confirmed by Raman and UV absorption spectra. The excellent anisotropic sliding properties of the surface of the assembled fibers were characterized by the water contact test. This work provides an idea for the preparation of smart sensing materials and lays a foundation for the wider application of P3HT. Â© 2021 Society of Chemical Industry

电场感应调控聚噻吩晶须及薄膜表面各向异性的研究

近年来，聚噻吩（P3HT）已成为一种典型的适合大规模应用的共轭高分子材料。然而，由于分子链的缠结和固有的柔韧性，很难获得具有高度有序排列的长 P3HT 纤维。在这项工作中，P3HT 纤维通过电场诱导技术成功构建和组装，可以直接观察。P3HT 分子的取向由拉曼和紫外吸收光谱证实。通过水接触试验表征了组装纤维表面优异的各向异性滑动性能。该工作为智能传感材料的制备提供了思路，为P3HT的更广泛应用奠定了基础。© 2021 化学工业协会
