Description
Summary:Cellulose acetate (CA) has been a material of choice for spectrum of utilities across different domains ranging from high absorbing diapers to membrane filters. Electrospinning has conferred a whole new perspective to polymeric materials including CA in the context of multifarious applications across myriad of niches. In the present review, we try to bring out the recent trend (focused over last five years' progress) of research on electrospun CA fibers of nanoscale regime in the context of developmental strategies of their blends and nanocomposites for advanced applications. In the realm of biotechnology, electrospun CA fibers have found applications in biomolecule immobilization, tissue engineering, bio-sensing, nutraceutical delivery, bioseparation, crop protection, bioremediation and in the development of anti-counterfeiting and pH sensitive material, photocatalytic self-cleaning textile, temperature-adaptable fabric, and antimicrobial mats, amongst others. The present review discusses these diverse applications of electrospun CA nanofibers. ► Recent progress of electrospun cellulose acetate (eCA) nanofibers is focused. ► Novel synthesis protocols and development of eCA nanocomposites are highlighted. ► Avant-garde applications for biomedical and industrial domains are featured. ► eCA in drug delivery, tissue engineering, crop protection and bioremediation ► Development of eCA based biosensors, self-cleaning and antimicrobial textiles
