Abstract

The use of electrostatic forces to shape materials processed from solution provides exciting opportunities to enhance material properties by creating new structures and morphologies during processing. In this context we report the formation of nanoscale webs composed of interconnected electrospun polymer fibrils. These nanowebs have been formed from synthetic spider silk, collagen, and denatured collagen when they are electrospun from various concentrations of formic acid. These nanowebs have been characterized by field emission scanning electron microscopy (FESEM) in order to characterize their morphology and measure their surface areas.
