Abstract

Halloysite nanotubes(HNTs) were composed into polyamide 6(PA6) matrix by ultilizing an in-situ polymerization process. This study includes two parts. The first part was fabrication of HNTs slurry, the zeta potential of halloysite nanotubes in aqueous solution without dispersant were measured. In the second part, HNTs slurry and ε-caprolactam (CPL) were mixed with a constant fraction of, after open-ring reaction, polymerization, then cooled, the 1wt% halloysite PA 6 composite was obtained. The results show that, the 11wt% HNTs slurry with a pH value is 9.27 exhibits a zeta potential of -43.79mV. The 1wt% PA6/HNTs composite solution exhibits a spunable relative viscosity value is 3.075. The initial decomposition temperature of PA6/HNTs composite is 19.16℃ higher than that of neat PA6, but their melt point are close.

摘要

本研究以原位聚合法之方式，將埃洛石奈米管與聚醯胺6製備成複合材料。研究包含兩個部分，第一部分先製備埃洛石懸浮液，第二部分將製備好之埃洛石懸浮液與己內醯胺均勻混合，經過開環反應、聚合反應、冷卻、破碎、純化、乾燥之程序製得聚醯胺6/埃洛石奈米複合材料。經研究分析後發現，固含量11wt% pH 9.27之埃洛石懸浮液，其表面電位達-43.79mv，埃洛石含量1wt%之聚醯胺6/埃洛石奈米複合材料其相對黏度為3.075，具有可紡性，其初始裂解溫度比未添加聚醯胺6提高了19.16℃，且對聚醯胺6之熔點不會有影響。
