Abstract

The interaction between poly(HEMA) which is material of contact lens containing about 45% water and amino acids (alanine, arginine, methionine, proline, glycine, serine, lysine) have been studied by using the thermal analysis methods through DSC and TGA. The experimental results of DSC and TGA were shown that lysine, arginine and alanine have the most stable interaction between poly(HEMA) and amino acids.

Poly(2-hydroxyethylmethacrylate, HEMA)는 contact lens 재료물질로 사용되고, 물을 약 45퍼센트 포함하여 수화겔(hydrogel)을 만들 수 있는 고분자이다. Poly(HEMA)와 아미노산(alanine, arginine, methionine, proline, glycine, serine, lysine)과의 상호작용력을 DSC와 TGA 열분석법으로 측정한 결과 lysine, arginine, alanine의 결합성이 큼을 알 수 있었다.
