SOLVENT EVAPORATION IN A BINARY SOLVENT SYSTEM FOR CONTROLLABLE FABRICATION OF POROUS FIBERS BY ELECTROSPINNING

ABSTRACT
Solvent evaporation is used for fabrication of nanoporous fibers by electrospinning, where multiple solvents are used. Pore size and distribution can be con-trolled by the fractions of the spun solution. An experiment was carefully designed, where polysulfone and poly(lactic acid) were dissolved in a binary sol-vent of dichloromethane and dimethylacetamide, to reveal the controllable process for fabrication of nanoporous fibers.
