Abstract

Recently, Importance of studying based on biomass materials have increased due to the concern about plastic waste problems. Cellulose acetate butyrate (CAB) is a potential alternative to petroleum-based plastics because of its biodegradable property. Poly(ethylene-co-isosorbide terephthalate) (PEIT) is bio-based plastic, produced by isosorbide monomer. In this study, CAB/PEIT blends were prepared by solution blending to improve thermal stability of CAB. CAB and PEIT were dissolved in chloroform, and then precipitated in ethanol. To evaluate the compatibility of CAB/PEIT blends, the morphology and glass transition behaviors were analyzed by FE-SEM and DMA, respectively. TGA results revealed the improved thermal stabilities of the PEIT-rich and 50:50 compositions. No new or changed crystal structures were observed in the XRD result. Finally, CAB/PEIT solution blends showed good compatibility in overall compositions.

최근, 플라스틱 남용으로 인해 바이오매스 기반 물질에 대한 연구의 중요성이 증가하고 있는 추세이다. Cellulose acetate butyrate (CAB)는 생분해성의 성질 때문에 재생이 가능하여 잠재성을 가지고 있는 고분자이다. Poly(ethylene-co-isosorbide terephthalate) (PEIT)는 아이소소바이드 모노머로부터 유래된 바이오매스 기반의 고분자이다. 본 연구에서는 다양한 분야에 적용되고 있지만 열안정성이 낮은 CAB에 내열성이 높은 PEIT를 도입하여 용액 블렌딩 방법을 통해 CAB/PEIT 블렌드를 제조하였다. 블렌드의 상용성을 판단하기 위해 모폴로지와 유리전이온도의 거동을 FE-SEM, DMA를 사용하여 분석하였다. TGA 결과는 CAB/PEIT 75/50, 50/50 조성에서 향상된 열적 안정성을 나타내었으며 XRD에서 새로운 결정 구조는 관찰되지 않았다. 결과적으로 CAB/PEIT solution blends는 모든 조성에서 좋은 상용성을 가짐을 확인하였다.
