초록
N,N-dimethylamino ethyl methacrylate(DMAEMA)와 poly(ethylene glycol) (PEG)로 이루어진 블록 공중합체를 합성하였고, 그 구조를 FT-IR, DSC, 및 1H-NMR로 확인하였다. 준비된 poly(DMAEMA)-PEG 블록 공중합체 수용액에 poly(ethyl acrylamide)(PEAAm)를 첨가하면 블록 공중합체의 DMAEMA와 poly(EAAm)사이에서 일어나는 수소결합에 의해 나노복합체가 형성되었다. 나노복합체는 임계미셀농도 이상의 농도에서 이루어졌다.
The synthesis of poly(N,N-dimethylamino ethyl methacrylate(DMAEMA)-block-poly(ethylene glycol)(PEG)) copolymer has been carried out and the block copolymer was characterized by FT-IR, DSC, and 1H-NMR. The formation of polymeric nanoaggregation was observed in the solution mixture of poly(DMAEMA)-block-PEG copolymer and poly(ethyl acrylamide)(EAAm) due to the intermolecular interaction via hydrogen bond between above critical micelle concentration(CMC).
Keywords:polymeric nanoaggregation;poly(DMAEMA)-block-PEG;lower critical solution temperature(LCST);critical micelle concentration(CMC);hydrogen bond
