초록
중성염에 용해한 후 얻어진 견피브로인 수용액의 pH를 3.0으로 조정하였을 때 피브로인 분자쇄들간에 정전기적 반발력이 감소하여 피브로인 분자쇄 상호간에 결합력이 증가하므로 겔화시간이 단축되었고 적외선분광분석 결과
Silk fibroin dissolved in highly concentrated calcium chloride and ethanol mixture aqueous solution turned into gel under suitable conditions. Preparation conditions and properties of gel were investigated as a function of parameters such as pH of solution, fibroin concentration, glycerol concentration and molecular weight. When pH of silk fibroin aqueous solution was near the isoelectronic point(pH 3.9~4.0), gelation occurred rapidly and strength of gel was stonger than that of pH-unadjusted due to electrostatic repulsion decrease between silk fibroin macromolecules. As concentration of silk fibroin and glycerol was higher, gelation occurred more rapid. FT Infra-red spectra of freeze-dried fibroin gel showed that gelation was derived by intermolecular anti-parallel
