Abstract

The purpose of this work was to develop a simple method to produce self-supported films composed of hydroxypropyl methylcellulose (HPMC) and polyaniline (PANI) by the direct mixture of aqueous dispersions of both polymers with subsequent drying. The addition of HPMC, a cellulose derivative with an excellent film-forming capacity, was fundamental to overcoming the poor processability of PANI, which impairs its use in many technological applications. All films showed conductivity in the order of 10 to 10 S cm, which is in the range for metals or semiconductors. The typical electroactivity of PANI was also maintained in the hybrid films. The thermal stability and the mechanical properties of the pristine PANI were also improved with the addition of HPMC. Cellulose-containing conducting polymers can be considered a material of the future, with possible applications in several areas, such as smart wallpapers, e-papers, and sensors.

摘要

这项工作的目的是开发一种简单的方法，通过将两种聚合物的水分散体直接混合并随后干燥，来制备由羟丙基甲基纤维素（HPMC）和聚苯胺（PANI）组成的自支撑膜。添加具有优异成膜能力的纤维素衍生物HPMC，对于克服聚苯胺加工性能差的问题至关重要，聚苯胺加工性能差会影响其在许多技术应用中的使用。所有薄膜的电导率在10至10 S/cm的范围内，这属于金属或半导体的范围。聚苯胺的典型电活性在混合薄膜中也得以保持。添加HPMC后，原始聚苯胺的热稳定性和机械性能也得到了改善。含纤维素的导电聚合物可被视为未来的一种材料，可能在多个领域得到应用，如智能壁纸、电子纸和传感器。
