초록

poly[hexamethylene carbonate]glycol(PHMCG)과 isophorone diisocyanate (IPDI), dimethylol propionicacid(DMPA)를 이용하여 수분산성 폴리우레탄을 합성하였다. 또한 여기에 나노 clay(PM) 및 이를 각기 다른 유기화제로 개질시킨 C15A와 C30B를 첨가하여 폴리우레탄/clay 나노복합재료를 제조하였다. 제조된 나노복합재료에서의 clay의 분산정도를 XRD를 이용하여 조사하였으며 clay가 첨가된 경우의 기계적 물성 및 열적성질을 UTM 과 TGA를 통하여 분석한 결과, C15A가 첨가된 경우 나노clay가 폴리우레탄에 가장 잘 분산된 것으로 관찰되었으며, 기계적 물성과 열적 물성이 C30B 또는 PM을 첨가한 경우보다 높게 측정되었다. 이로부터 clay에서 개질유기화제의 종류 및 함량이 나노복합재료의 최종물성에 영향을 주는 것을 알 수 있었다.

In this study, aqueous polyurethane dispersion(PUD) was synthesized using polyhexamethylene carbonate glycol (PHMCG) as soft segment, isophorone diisocyanate (IPDI) and dimethylol propionic acid (DMPA) as hard segment. Also, polyurethane/clay nanocomposites were prepared by adding pristine montmorillonite (PM) and organically modified clays, C15A and C30B into PUD. The degree of clay dispersion in the nanocomposites was investigated using XRD and the physical and thermal properties were examined through UTM and TGA. These results showed that nanocomposites with C15A gave higher physical and thermal properties than those with C30B or PM. As a result, the properties of nanocomposites were observed to vary depending on the types of clay modifiers and clay contents.
