摘要
将聚乙烯醇(PVA)的水溶液与聚3,4-乙撑二氧噻吩:聚对苯乙烯磺酸(PEDOT:PSS)水分散液共混,以甲醇作为凝固浴,通过湿法纺丝制得PVA/PEDOT:PSS共混导电纤维。通过改变湿法纺丝后处理过程中的退火工艺,探究不同的退火工艺对PVA/PEDOT:PSS共混导电纤维性能的影响。通过红外光谱分析仪、高阻计、电子单纤维强力仪和扫描电子显微镜对共混纤维的结构与性能进行测试表征。结果表明,随着退火温度的增加及退火时间的延长,PVA/PEDOT:PSS共混导电纤维的电导率均呈现出增加的趋势;单纤维拉伸强度逐渐增加,拉伸断裂伸长率逐渐减小;纤维表面粗糙度增大,沟槽数量增多。
Poly(vinyl alcohol)(PVA) aqueous solution was mixed with aqueous dispersion of poly (3,4-ethylenedioxythiophene) : poly(styrene sulfonate)(PDOT : PSS), from which a blend fiber was prepared by wet-spinning using methyl alcohol as a coagulation bath. The effect of annealing temperature and time on the property of the blend fiber were characterized by FTIR, SEM, high resistance meter, and single fiber strength tester. As the annealing temperature and time increased, the electrical conductivity, tensile strength of the fiber increased; while the elongation at break decreased, surface roughness and the number of tiny grooves.
