Abstract

In this study, we synthesized the aminoclay (AC) with magnesium ions and 3-aminopropyl triethoxysilane (APTES). At the same time, propolis intercalated aminoclay (PIAC) and coptis extract intercalated aminoclay (CIAC) were synthesized by intercalating natural chemicals between clay sheets. Clay synthesis and natural chemical intercalation were confirmed through SEM, particle size analyze, FT-IR, TGA and XRD. In particular, the characterization of intercalation of natural chemicals was determined by analyzing the interlayer distance from XRD data. The antimicrobial property of PIAC and CIAC was checked by minimum inhibitory concentration (MIC) test and increased compared with that of the pristine aminoclay (AC).

초록

본 연구에서는 마그네슘 이온 및 (3-aminopropyl)triethoxysilane (APTES)으로 표면에 amine group이 부착된 아미노클레 이를 합성(AC)함과 동시에 천연 화합물인 프로폴리스 및 황련 추출물을 클레이 시트 사이에 삽입한 클레이를 합성 (PIAC, CIAC)하였다. 주사전자현미경, 입도 분석법, FT-IR, TGA 및 XRD를 통해 클레이의 합성 및 천연 화합물의 삽입 을 확인하였고, 특히 XRD data에서 천연 화합물의 삽입에 따른 층간거리(d-space)를 분석함으로써 명확하게 그 특성을 결정하였다. 또한 천연 화합물이 삽입된 클레이인 PIAC 및 CIAC의 경우 삽입되지 않은 아미노클레이(AC)에 비해 항균성이 향상된 것을 최소저해농도(MIC) 분석을 통해 확인하였다.
