- W2088193427 abstract "나노섬유의 경우 넓은 비표면적과 높은 공기투과도 등으로 인해 여러 분야에 폭넓게 활용될 것으로 기대되고 있다. 또한 석유화학 기반 고분자의 경우 가채연수 제한문제와 이산화탄소 배출에 의한 온실가스 유발문제로 인해 바이오매스 유래 고분자로의 패러다임의 전환이 절실히 요구되고 있는 실정이다. 따라서 본 연구에서는 목질계 셀를로오즈로부터 유래된 플랫폼 화합물 중 퓨란계 유도체인 2,5-furandicaboxylic acid와 ethylene glycol을 이용하여 이를 중합한 바이오매스 유래 PEF(polyethylene furoate)를 제조 및 이를 활용하여 전기방사법을 통해 나노섬유를 제조하고자 하였으며, 또한 전기방사 과정에서 사용된 용매와 고분자 용액의 농도, 전기장의 세기 등의 변수들이 섬유형상에 어떠한 영향을 미치는지 고찰하고자 하였다. 결론적으로, PEF 15 wt%의 농도로 HFIP를 용매로 제조한 고분자 용액을 이용하여 약 200~700 nm의 나노섬유의 제조가 가능하였으며, 섬유의 직경은 인가된 전기장의 세기가 증가할수록 증가하였다. Nanofibers have attracted significant interest in many industrial fields because their high surface area and porosity. In addition, the continued use of petrochemical based polymers has caused the depletion of oil resources and accelerated the greenhouse effect by the emission of carbon dioxide. Therefore, biomass-based polymer has become a very important environmentally friendly alternative. In this study, nanofibers were fabricated by an electrospinning process using biomass based PEF(polyethylene furoate) prepared by the polymerization of 2,5-furandicaboxylic acid and ethylene glycol. Furthermore, the electrospun nanofiber was strongly affected by various parameters, such as the solvent, polymer concentration and electric field. In conclusion, nanofibers with an average fiber diameters of 200 - 700 nm could be prepared at polymer concentration of 15 wt% using HFIP, and their fiber diameter increased with increasing electric field." @default.
