pH-Responsive Electrospun Nanofibers and Their Applications

Electrospun nanofibrous membranes offer superior properties over other polymeric not only due to their high membrane porosity but also surface-to-volume ratio. A plethora of available polymers and post-modification methods allow the incorporation "smart" responsiveness in fiber membranes. The pH-responsive property is achieved using from class polyelectrolytes, which contain pH-dependent functional groups on backbone. Electrospinning macroscopic polyelectrolytes earned considerable interest for biomedical environmental applications possibility trigger chemical physical changes (swelling, wettability, degradation) response pH-changes. Here, we review recent advancements field electrospinning nanofiber materials. Starting with background at molecular level, highlight material-property transformation upon pH-change level and, finally, provide an overview
