Abstract

Dissolution of Antheraea pernyi silk fiber was carried out in a zinc chloride solution with various dissolving conditions. The solubility was significantly dependent on the concentration of zinc chloride, dissolving temperature and time. The proper conditions of dissolution were found as 8 M zinc chloride, 70$^{\circ}C$ temperature and 30 min dissolving time. Regenerated A. pernyi silk fibroin powder was obtained through dialysis. FTIR and XRD showed that regenerated A. pernyi silk powder was composed of a ${\beta}$-sheet as well as an ${\alpha}$-helix conformation.

염화아연에 의한 작잠 견사의 용해 조건을 살펴본 후 투석법에 의하여 얻은 작잠 견피브로인 분말의 형태와 적외선 분광 특성 및 X-선 회절 특성을 살펴본 결과 다음과 같은 결론을 얻었다. 1. 작잠 견사는 고농도의 염화아연 수용액에 용해되었으나 용해 조건을 조절하여 완전하게 작잠 견사를 용해할 수 있었다. 2. 재생 작잠 분말의 구조 특성을 살펴보기 위하여 적외선 분광분석과 X-선 회절분석을 행한 결과 작잠분말은 $\beta$-sheet 구조와 $\alpha$-helix 구조로 이루어져 있었다. 3. 염화아연을 사용하여 제조한 작잠 견피브로인 용액으로부터 순수한 작잠 견피브로인을 얻기 위한 새로운 방법이 개발되어야 함을 알 수 있었다.
