The article reviews some significant research trends in the development of innovative products from electrospun nanofibers. In one area of investigation, high surface area poly (lactic acid) (PLA)/tea polyphenols (TPs) porous composite nanofiber membranes (CNFMs) were prepared successfully by electrospinning and applied to adsorption of silver ions. In another area of research electrospun PVA/SiO2 separator membranes were presented and their electrochemical performance was evaluated for use in Li-ion batteries. Polyvinyl alcohol (PVA) was used to prepare nanofiber based membranes due to advantages such as low cost, water solubility, and biodegradability. In yet another work, a mixture of formic acid (FA), acetic acid (AA), and acetone was used, for the first time, as a ternary solvent system to dissolve poly(E-caprolactone) (PCL). In addition, as a biomaterial reinforcement, various amounts of cellulose microfibrils (CMF) (1.5, 3, and 5wt. %), extracted from rice husk, were added to PCL solution, and subsequently the prepared suspensions were individually electrospun.
