A vast range of synthetic and biopolymers have been electrospun. Electrospinning low molecular weight polymers, polyelectrolytes, and some biomacromolecules have been limited. A common approach to form fibers from such materials is to blend the nonelectrospinnable polymer with an easily electrospinnable polymer (Schiffman and Schauer 2008; Wang et al. 2015; Wendorff et al. 2012; Tang et al. 2012; Saquing et al. 2013). The carrier polymer is typically high molecular weight that forms a well‐entangled network at low concentrations (Schiffman and Schauer 2008; Saquing et al. 2013). For example, biopolymers such as chitosan or alginate are often blended with PEO (Schiffman and Schauer 2008; Saquing et al. 2013). The electrospinnable polymer increases the elasticity of the blend to enable formation of nanofibers (Yu et al. 2006).
