Abstract
A polymer-micelle complex suitable for use as an aid to preparing fibers, particularly nanofibers, by electrospinning. The polymer-micelle complex may be designed to impart viscosity, surface tension and conductivity properties optimal for electrospinning. By incorporating the complex as a secondary ingredient, one may electrospin sparingly soluble or low molecular weight polymers. Moreover, the polymer-micelle complex can be used as a generic carrier for preparing fibers incorporating other desired materials, such as rigid or globular (hard-to-spin) polymers, enzymes, cells, viral particles and nanoparticles.
