Abstract

Biodegradable enzymes such as lipase and proteinase can hydrolyze not only fatty acid esters and triglycerides, but also aliphatic polyesters. We measured the biodegradability that biodegradable enzymes have an important role in the degradation of natural aliphatic poly material such as PLA, corn starch, and polyethylene glycol in the natural environment. However, we investigated on the biodegradability of PLA, PLA and Polyethylene acrylate blended, and PLAcoPolyethylene polymerized with PLA graft copolymer Polyethylene glycol acrylate. When prepared biodegradable polymers. the Mechanical properties of them were measured on Biodegradability, thermal properties, real time in-situ electrical monitoring of polymers resin. Therefore BOD and biodegradation of PLAcoPolyethylene was graft copolymerized with PLA and polyethylene acrylate were measured at a lower rate than the other samples.

리파아제 및 프로테이나아제와 같은 생분해성 효소는 지방산 에스테르 및 트리글리 세라이드뿐만 아니라 지방족 폴리에스테르를 가수 분해가 가능하다. 본 연구에서는 생분해성 효소가 자연 환경에서 PLA, 옥수수 전분 및 폴리에틸렌글리콜 등의 천연 지방족 폴리 물질이 분해에 중요한 역할인 생분해성을 측정했다. 본 실험에서는 PLA, PLA와 폴리에틸렌아크릴레이트, PLA 그라프트 중합체인 폴리에틸렌글리콜아크릴레이트를 사용한 PLAcoPolyethylene의 생분해성에 대해 실험하였다. 생분해성 고분자를 합성할 때. 이들의 기계적 특성은 생분해성도, 열적특성, 실시간으로 폴리머 수지의 전기적 모니터링을 통해 실험측정 결과, BOD와 PLAcoPolyethylene의 생분해도는 PLA와 그라프트 공중합된 폴리에틸렌아크릴레이트는 다른 시료보다 낮은 속도로 측정되었다.
