Abstract
Rectangular cellulose microfibers were synthesized by regenerating cellulose from an ionic liquid, 1-ethyl-3-methylimidazolium acetate, in a hydrodynamic flow-focusing microfluidic device. This technique is a fast and single-step approach for producing natural polymer microfibers. The dimensions of the cellulose microfibers were readily controlled by a simple variation of the core-sheath flow rate and the viscosity of fluids.

마이크로플루이딕 디바이스 내에서 셀룰로오스가 녹아있는 이온성 액체(1-에틸-3-메틸-이미다졸리움 아세테이트)로부터 셀룰로오스의 추출을 통한 직사각형의 단면적을 가지는 셀룰로오스 마이크로 파이버를 제조하였다. 본 연구에서 제안하는 방법은 빠른 시간 내에 간단하게 천연고분자 마이크로 파이버를 제작하기에 적합한 제조방법으로 적용가능하며, 이온성 액체와 주변 글리세린 용액의 유속비와 용액의 점도에 따라 다양한 크기의 셀룰로오스 마이크로 파이버를 제조하였다.
