【摘要】 <正> 聚苯胺(PANI)由于具有多样的结构、独特的掺杂机制、优异的物理化学性能、良好的环境稳定性等优点,已成为导电高分子研究的热点和推动力之一。聚丙烯腈(PAN)纤维俗名腈纶,是较早实现工业化生产的合成纤维之一。使用聚苯胺与聚丙烯腈共混,制备导电材料的研究国内外尚未见报道。本文首先利用乳液聚合法制备十二烷基苯磺酸掺杂的聚苯胺(PANI-DBSA),然后采用CHCl3与DMSO的体积比为15:85的混合溶剂,制备不同组成的PANI-DBSA/PANI的共混溶液,采用锥板式流变仪对其流变性能进行测试;讨论温度、共混组成及剪切速率对流变性能的影响,为PANI/PAN导电纤维的开发和应用提供必要的依据。更多还原

【Abstract】 Rheological behavior, micromorphology and their interrelation in blends of PANI-DBSA/PAN were investigated. It was found that namely, the apparent viscosity of blend solution decreased at low PANI-DBSA content (2.5 wt%) while increased at high PANI-DBSA content (7.5-10 wt%). Moreover, the shear-thinning appeared more distinct with the incorporation of PANI-DBSA into the blend solutions especially under high shear rate. It was believed that the relationship between dispersion and content of PANI-DBSA and the variation of dispersion along with shear rate should contribute to those complicated rheological phenomena.更多还原
