초록
본 연구에서는 (3-aminopropyl)triethoxysilane을 사용하여 표면을 아민기로 관능화함과 동시에 팔면체와 사면체 구조를 가지는 마그네슘-층상규산염(AF-MgP)을 합성하였다. FT-IR과 XRD 분석을 통해 AF-MgP가 성공적으로 합성되었음과, 입자 표면의 아민기 및 1 : 2 비율의 팔면체와 사면체 구조를 확인하였다. HR-SEM와 EDX 분석을 통해 면섬유 표면에 AF-MgP가 고루 흡착되어 섬유를 코팅하고 있음을 확인하였다. KS 규격에 따른 섬유의 항균력 시험 결과 AF-MgP 입자가 코팅된 면섬유는 피부 상재균에 대해 매우 우수한 항균 활성을 나타내는 것을 확인하였다. 이상의 결과들은 AF-MgP가 섬유에 항균성을 부여해주는 기능성 나노 소재로서 적용될 뿐만 아니라, 화장품이나 의료 소재 분야에서 응용이 가능함을 시사한다.
In this study, we synthesized amine-functionalized magnesium-phyllosilicates (AF-MgP) with an octahedral and tetrahedral structure using (3-aminopropyl)triethoxysilane. The synthesis of AF-MgP, surface functionalization of amine and 1 : 2 ratio of the octahedral and tetrahedral structure were confirmed by FT-IR and XRD analysis. In addition, it was confirmed that AF-MgP was absorbed evenly on the surface of cotton fibers and coated on the cotton fibers from HR-SEM and EDX analysis. The antimicrobial activity test of cotton fibers according to KS confirmed that cotton fibers coated with AF-MgP particles show an enhanced antimicrobial activity against cutaneous microorganisms. Our results suggest that AF-MgP is not only applied as a functional nanomaterial that gives the cotton fiber antimicrobiality, but also can be used in the field of cosmetic and biomedical materials.
