Tailored fibro-porous structure of electrospun polyurethane membranes, their size-dependent properties and trans-membrane glucose diffusion

Electrospun membranes have traditionally been used as nano-filtration systems and lightweight fabrics. More recently, they have become very popular in biomaterials and tissue engineering research because of their high surface to volume ratios and the electrospinnability of a variety of materials. Here, we showed that controllable pore sizes and thickness, high pore volumes and excellent pore interconnectivity of electrospun membranes can aid better mass transport compared to traditional solvent cast membranes. This publication is the culmination of the research funded through Royal Society’s RG100129 and JP1011064 and NIH/NIBIB – R01EB001640 grants.
