Fabrication and characterization of electrospun cellulose acetate nanofibers derived from rice husk for potential wound healing application

Abstract

As one of the world's most abundant biomass, lignocellulosic materials such as rice husk (RH) has been recognized for its various potential usages. Electrospun nano brous mats have been fabri-cated from various natural and synthetic polymers and offers a wide range of promising criteria suitable for wound dressing applications. Natural polymers have grabbed considerable attention due to their desirable properties. Therefore, the application of cellulose-derived materials from agricultural waste becomes crucial as a green alternative to produce electrospun wound dressing with excellent wettability, porosity and tunability to promote wound healing at relatively low costs. Interestingly, a speci c study on the utilization of cellulose extracted from RH to produce electrospun nano brous mat remains unreported.Therefore, this work aimed to investigate the feasibility of using RH as a source of raw materials to create nano brous mats for use as pro-spective wound dressing materials. In this paper, cellulose extracted from RH will be converted into its derivate, cellulose acetate (CA) and electrospun. The nano ber will be characterized by Scanning Electron Microscope (SEM), Attenuated Total Re ectance-Fourier transform spectros-copy (ATR-FTIR), water contact angle to evaluate the main properties of the electrospun nanobrous mat.
