가교 전분을 충전한 수성 아크릴레이트 필름의 기계적 특성과 α-Amylase에 의한 생분해 = Mechanical Properties of Crosslinked Starch-Filled Waterborne Acrylate Film and Biodegradation by α-Amylase

다국어 초록 (Multilingual Abstract)

Starch was crosslinked with epichlorohydrin. Crosslinked starch-filled waterborne acrylate (CSWAC) films were prepared by blending this crosslinked starch with waterborne acrylate. The thermal and mechanical properties of these films were investigated by thermogravimetric analysis (TGA), tensile strength and elongation test. The biodegradability was also studied by determination of reduced sugar products after enzymatic hydrolysis and the surface morphology was investigated by scanning electron microscopy (SEM).
The CSWAC film showed significantly higher tensile strength and elongation than those of starch-filled waterbonre acrylate (SWAC). The biodegradability of this film was higher than that of native starch-filled acrylate film, and was increased by the addition of crosslinked starch to the acrylate film.
