纳米纤维素增强聚苯胺复合材料的制备及性能

 为制备一种新型聚苯胺导电复合材料，以盐酸作为掺杂酸，过硫酸铵作为氧化剂，采用原位聚合法，将从废报纸中提取的纳米纤维素与苯胺单体复合，合成了纳米纤维素增强聚苯胺导电复合材料。分别利用傅里叶红外光谱仪（FTIR）、扫描电镜（SEM）、四探针测试仪、万能力学实验机，测试纳米纤维素增强聚苯胺导电复合材料的化学成分、微观结构、导电率、力学性能。结果表明，当聚苯胺的质量分数达到20%时，掺杂纳米纤维素的聚苯胺复合材料保持了良好的导电性能，同时提高了韧性。

Preparation and Properties Analysis of Nanocellulose Reinforced Polyaniline Composites

To prepare a novel polyaniline conductive composite, nanocellulose reinforced polyaniline conductive composites were prepared using the method of in situ polymerization, where hydrochloric acid was used as the doping agent, and ammonium persulfate as the oxidant. The chemical composition, microstructure, electrical conductivity and mechanical properties of the composite were tested by fourier transform infrared spectroscopy, scanning electron microscopy, a four-probe tester and a universal mechanical testing machine. The results show that when the mass fraction of polyaniline reached 20%, the composite of nanocellulose reinforced polyaniline maintained good electrical conductivity and improved toughness.
