Abstract
The invention provides novel polymer nanofiber or microfiber mats or membranes and methods for their preparation via an aqueous, one-step polyelectrolyte complexation and electrospinning of complex coacervates.
Claims12
A method for making a nanofiber or microfiber by electrospinning, comprising:
- providing an aqueous solution comprising a polyanion or macroanion and an aqueous solution comprising a polycation or macrocation;
- mixing the aqueous solution comprising a polyanion or macroanion, the aqueous solution comprising a polycation or macrocation, and an aqueous salt solution to form a coacervate suspension;
- coalescing the coacervate suspension into a homogeneous coacervate phase;
- and
- electrospinning the coacervate phase to form a nanofiber or microfiber, wherein the nanofiber or microfiber has a diameter in the range from about 0.199 micrometers to about 32 micrometers.
