摘要

利用静电纺丝法制备了含有一定质量FeCl₃的聚丙烯腈/氯化铁(PAN/FeCl₃)三维(3D)纳米复合材料,并通过进一步的预氧化及碳化处理得到了带有柔性的碳化3D导电的纳米复合材料。且对3D导电纳米复合材料的微观结构和压阻性能进行了测量和分析。结果表明:碳化后的柔性3D导电纳米复合材料具有较高的孔隙率并呈现出疏水特性,Fe₃O₄被均匀分散在整个碳化纤维的表面,在测试压阻性能中3D导电纳米复合材料对不同质量的砝码有明显的且可区分的相对电阻变化率响应,并对手指的单击和双击有较快且可重复的响应。

Abstract

A polyacrylonitrile/ferric chloride (PAN/FeCl₃) three-dimensional (3D) nanocomposite material containing a certain mass of FeCl₃ was prepared by electrospinning,and through further pre oxidation and carbonization treatment to prepare flexible 3D conductive nanocomposite material.And the microstructure and piezoresistive properties of the nanocomposites were measured and analyzed.The research shown that the nanocomposite had high porosity and exhibited hydrophobic characteristics.Fe₃O₄ was evenly dispersed on the surface of the carbonized fiber.In the test of the piezoresistive performance,the nanocomposite had obvious and distinguishable response to the relative resistance change rate of different weights,and had quick and repeatable response to the single click and double click of the finger.
