Abstract

Villi-structured polyaniline sheets (VPASs) were synthesized by the organic single-crystal surface-induced polymerization (OCSP) method using sodium decanesulfonate as a template. Aniline hydrochloride is used as a monomer instead of aniline to improve the electrostatic interaction between monomers and hydrated crystals, which reveals that the mechanism of OCSP occurs from the electrostatic force between positively charged monomers and the negatively charged surface of hydrated crystals. Compared with conventional polyaniline (3.13 × 10 S/cm), VPASs showed higher electrical conductivity (1.07 × 10 S/cm). The thickness of double-layered VPASs is about 136 nm, and the surface of VPASs shows a random porous structure with a villi-like morphology. This morphological property provides a large surface area, which can be advantageous to various electrochemical applications. The process yields mass-producible inexpensive materials, and the products are suitable for flexible devices because of their characteristic morphology.

摘要

采用癸烷磺酸钠作为模板，通过有机单晶表面诱导聚合（OCSP）法合成了绒毛状结构聚苯胺片材（VPASs）。使用盐酸苯胺代替苯胺作为单体，以改善单体与水合晶体之间的静电相互作用，这表明OCSP的机理源于带正电的单体与水合晶体带负电表面之间的静电力。与传统聚苯胺（3.13×10 S/cm）相比，VPASs表现出更高的电导率（1.07×10 S/cm）。双层VPASs的厚度约为136nm，其表面呈现出具有绒毛状形态的随机多孔结构。这种形态特性提供了较大的表面积，这对各种电化学应用可能是有利的。该工艺可大量生产廉价材料，并且由于其独特的形态，产品适用于柔性器件。
