Abstract
Poly(vinyl alcohol) (PVA) and N-(2-hydroxy)propyl-3-trimethylammonium chitosan chloride (HTCC), a water soluble chitosan derivative synthesized by the reaction of quaternary ammonium compound with chitosan, were blended using water as a solvent and the PVA/HTCC blend films with various compositions were prepared by solution casting method. The miscibility between the two polymers and the thermal properties of the blend films were investigated using FT-IR, DSC, DMA, and TGA. Single glass transition temperatures and single melting temperatures of the blend films along with the strong and clear film state for the whole composition of blending ratios suggest the miscibility between PVA and HTCC. The PVA/HTCC blend films with HTCC content of 1% and greater showed excellent antimicrobial activity.

수용성 고분자인 폴리(비닐 알코올) (PVA)과 키토산에 제4급 암모늄염을 도입하여 합성한 수용성 키토산 유도체인 N-(2-하이드록시)프로필-3-트리메틸 키토산 클로라이드 (HTCC)를 수용액 상태로 하여 용액 블렌딩하고 이를 캐스팅하여 PVA/HTCC 블렌드 필름을 제조한 후 두 고분자 사이의 혼화성과 블렌드 필름의 특성을 FT-IR, DSC, DMA 및 TGA를 사용하여 검토하였다. HTCC 함량을 50%까지 변화시킨 본 연구의 혼합 범위에서 블렌드 필름들은 모두 투명한 상태를 나타내었으며, Tg와 Tm 이 하나로 나타나 두 고분자 사이에 혼화성이 있음을 확인하였다. 또, HTCC의 우수한 항미생물성 때문에 HTCC가 1%만 포함되더라도 블렌트 필름은 우수한 항미생물성을 나타내었다.
