Abstract

Bio-based polymers including poly(ethylene 2,5-furandicarboxylate) (PEF), poly(propylene 2,5-furandicarboxylate) (PPF) and Poly(ethylene 2,5-furandicarboxylate-co-propylene 2,5-furandicarboxylate) (PEPF) were synthesized by reacting 2,5-furandicarboxylic acid (FDCA) with ethylene glycol (EG) and 1,3-propanediol (PDO). Chemical structures of synthesized polymers were characterized by FTIR and 1H NMR. In addition, the fraction of EG and PDO in copolymers were calculated from 1H NMR spectra. As the results, the fraction of PDO in copolymers was higher than EG compared to feeding ratio in synthesis. It is attributed to higher reactivity of PDO than EG. Synthesized polymers were melt-spun under different conditions according to the results of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). And the tensile properties of the fibers were evaluated. Tensile behavior of copolyester fibers exhibited similar behavior of undrawn fibers. Thus the feasibility of bio-based copolyester fibers were confirmed.


바이오 기반 고분자인 poly(ethylene 2,5-furandicarboxylate)(PEF), poly(propylene 2,5-furandicarboxylate) (PPF), poly(ethylene 2,5-furandicarboxylate-co-propylene 2,5-furandicarboxylate)(PEPF)를 2,5-furandicarboxylic acid(FDCA)와 ethylene glycol(EG) 및 1,3-propanediol(PDO)을 이용하여 합성하였다. 합성된 고분자의 화학적 구조를 FTIR과 1H NMR로 분석하였다. 또한 1H NMR 스펙트럼을 이용하여 합성된 공중합체의 EG와 PDO 분율을 계산하였으며, 그 결과 합성 시 투입 비율 대비 공중합체의 PDO 분율이 EG보다 높았다. 이를 통해 FDCA에 대한 반응성이 PDO가 EG보다 크다는 것을 알 수 있었다. Differential scanning calorimetry(DSC)와 thermogravimetric analysis(TGA) 분석결과에 따라 합성한 고분자를 용융방사하고, 인장특성을 확인하였다. Copolyester 섬유의 인장거동은 전형적인 미연신사 거동을 보였다. 본 연구에서 바이오 기반 copolyester를 섬유로 사용할 수 있는 가능성을 확인하였다.
