Nano Focus: Magnetic ferrofluid key to new take on spinning polymer fibers

1{D Isothermal Spinning Models for Liquid Crystalline Polymer Fibers

A slender 1{D model for laments of liquid crystalline polymers (LCPs) is applied to simulate isothermal ber spinning of materials with internal orientation. The model and predictions focus on the hydrodynamic{orientation interactions in spinning ows, isolated from other signi cant spinline e ects of temperature, crystallization and phase changes. An important practical feature of the model is t...

Microfluidic Spinning of Biodegradable Polymer and Cell Orientation Control on the Fibers

This paper reports microfluidic chip based wet spinning of biodegradable polymers with simple mechanism, and study of cell orientation dependence with fiber size. Biodegradable polymer PLGA fiber was produced by microfluidic chip based spinning device. By controlling feed rate of core polymer and sheath coagulating solutions, we got various PLGA fiber diameter from 10 to 242 μm. L929 mouse fibr...

Poster Presentations: Soft Matter

Reactive spinning of nanoand microfibers that involves very fast diffusion-limited chemical reaction and ion exchange is very challenging for the major nanofiber formation methods. The two-droplet reactive magnetospinning method introduced here offers a new technique for spinning fibers when the polymer formation or post-polymerization modification is limited by diffusion. This method can be re...
