Hydrogel Fibers Produced via Microfluidics

Hydrogel-Assisted Microfluidic Wet Spinning of Poly(Lactic Acid) Fibers from a Green and Pro-Crystallization Spinning Dope

“…As an emerging wet spinning technology, microfluidic wet spinning (MWS) confines coaxial laminar flow within a micrometer-scale channel, where the fiber formation can be induced by various methods, including solvent exchange, ionic crosslinking, and photopolymerization [29,30]. In addition to the flexibility in choosing controlled fiber solidification methods, the precise tuning of flow conditions enabled by nowadays commercial microfluidic pumping systems offers delicate manipulation of liquid flow conditions, which allows the control over fiber structural and mechanical properties by microfluidic wet spinning [31,32].…”
