以未漂蔗渣浆或稻草浆为纤维原料,以聚苯胺为导电性聚合物制备导电纸。聚苯胺由原位乳液聚合法合成,合成中以过硫酸铵(APS)作为氧化剂、以十二烷基苯磺酸(DBSA)作为乳化剂。利用傅里叶变换红外(FT-IR)光谱、热重(TGA)分析和差示扫描量热(DSC)分析表征聚苯胺纤维复合材料的特性,同时利用扫描电子显微镜观察其形态。电导率测试结果表明,随聚苯胺添加量的增加,纸张导电性增强;纸张强度测试表明,随聚苯胺添加量的增加,裂断长、耐破因子和撕裂因子均下降,尤其以蔗渣浆为基材更明显。新型导电纸有可能用作防静电包装材料。
Unpicked bagasse pulp or straw pulp as a fiber raw material, polyaniline conductive polymer prepared conductive paper. Polyaniline was synthesized by in-situ emulsion polymerization. Ammonium persulfate (APS) as oxidant and dodecylbenzenesulfonic acid (DBSA) as emulsifier were used in the synthesis. The properties of polyaniline fiber composites were characterized by Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Morphology was also observed by scanning electron microscopy. Conductivity test results show that with the increase of polyaniline, paper conductivity increased; paper strength test showed that with the increase of polyaniline dosage, long crack, breaking factor and tear factor are decreased, especially bagasse pulp More obvious for the substrate. New conductive paper may be used as anti-static packaging materials.
