摘　　要：为提高纺织品的多功能性如导电和疏水性等,在棉织物表面合成了疏水导电高分子材料聚吡咯。通过加入低表面能的掺杂剂来调控聚吡咯的疏水性与导电性,并对聚吡咯整理棉织物的表观形貌、电导率、接触角及K/S值等进行表征。结果表明,以木质素磺酸钠(LGS)为模板,掺杂0.025 mol/L全氟辛基磺酸钾(KPFOS)制得的聚吡咯整理棉织物疏水性能最佳,且达到超疏水状态;以蒽醌-2-磺酸钠盐(AQS)为软模板、掺杂十二烷基苯磺酸(DBSA)的聚吡咯复合棉织物电导率最大。以AQS为软模板且以0.01 mol/L DBSA掺杂的聚吡咯整理棉织物综合性能较好:接触角为131.2°,电导率为61.4 S/cm。因此通过模板的微观形貌控制以及烷基链或全氟烷基链的掺杂,可得到同时具备良好导电和疏水性能的聚吡咯整理棉织物,但其掺杂剂的调控机制仍需进一步研究。The hydrophobic conductive polypyrrole(PPy)was synthesized on the surface of contton fabrics to achieve functions,such as conductivity and hydrophobicity,which were regulated by changing the types of dopanTSwith different low surface energy.Morphology,contact angle,conductivity and K/S value were characterized accordingly.Experimental resulTSshow that the PPy coated cotton fabrics using sodium lignosulphonate(LGS)as template with 0.025 mol/L perfluorinated octyl sulfonic acid potassium(KPFOS)have the best hydrophobicity,and reaching the superhydrophobic state.PPy treated cotton fabrics using anthraquinone-2-sulfonic acid sodium salt(AQS)as the soft template with 0.01 mol/L dodecyl benzene sulfonic acid(DBSA)doped polypyrrole composites demonstrate best conductivity.The better comprehensive behaviors is achieved for the fabric using AQS and 0.01 mol/L DBSA dopant with the contact angle of 131.2°and conductivity of 61.4 S/cm.Through micromorphology control of the template and doping of the alkyl chain or perfluorinated alkyl chain,PPy coated cotton fabrics with good electrical conductivity and hydrophobic properties can be prepared,but their regulation mechanisms of doping still require further study.
