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).
