Ultrasonic-assisted deacetylation of cellulose acetate nanofibers: A rapid method to produce cellulose nanofibers

Ultrasonics Sonochemistry, 2017
Herein we report a rapid method for deacetylation of cellulose acetate (CA) nanofibers in order to produce cellulose nanofibers using ultrasonic energy. The CA nanofibers were fabricated via electrospinning thereby treated with NaOH and NaOH/EtOH solutions at various pH levels for 30, 60 and 90min assisted by ultrasonic energy.

Amorphous cellulose nanofiber supercapacitors [PDF]

Scientific Reports, 2021
AbstractDespite the intense interest in cellulose nanofibers (CNFs) for biomedical and engineering applications, no research findings about the electrical energy storage of CNF have been reported yet. Here, we present the first electroadsorption effects of an amorphous cellulose nanofiber (ACF) supercapacitor, which can store a large amount of ...

Fabrication of Ionic Cellulose Nanofiber Composites by Electrospinning Cellulose Microfibril-Gel-Dispersions in Poly(vinyl Alcohol) Solution

Journal of Natural Fibers, 2022
In this study, we propose a fabrication method to obtain composites of poly(vinyl alcohol) (PVA)/ionic cellulose nanofibers, in which a fiber structure is manipulated through a reconstruction of 2,2,6,6-tetramethyl-piperidinyl-1-oxyl radical (TEMPO ...

Fabrication and characterization of co-electrospun cellulose/poly (4-methyl-1-pentene) nanofibers with improved tensile properties

Materials Research Express, 2022
In this study, cellulose acetate and poly (4-methyl-1-pentene) (CA/PMP) nanofibers were co-electrospun with a blending ratio of 1:1 and followed by deacetylation treatment to produce cellulose/PMP nanofibers.
