| Abstract |
Keywords: Hyperbranched polymer, wet spinning, fiber
Hyperbranched polymers are three-dimensional macromolecules that having irregular branches on a polymer backbone. They have intramolecular cavities, low viscosity, and high solubility. [1]
Wet-spinning of polymeric material is a traditional method to make fiber. Fiber spinning of hyperbranched polymers seems to have received little attention, unlike linear polymer or polymer composites, because hyperbranched polymers exhibit low strength and low viscosity compared to linear polymers. However, the hyperbranched polymers have higher intrinsic solubility and lower melt or solution viscosity that favor easy spinning [2] and enhance manufacturing throughput.
We wet spun fibers using hyperbranched polymers and to date have found them to have a porous structure. The relationship between porosity of the polymer fiber and coagulation conditions (control of the speed of solvent exchange, relaxation time, and concentration of polymer solution) will be presented.
This research was supported by the Institute for Basic Science (IBS-R019-D1).
