“…The acetate ester of cellulose, cellulose acetate (CA), has been considered the most common biopolymer in the literature, obtained from the reaction of cellulose with acetic anhydride and sulfuric acid. 22 Its use as a template for electrospun ber production has attracted tremendous attention due to the unique niche in a plethora of environment-friendly applications of CA, such as development of antimicrobial membranes, 23 drug delivery systems 22,24 and separators for lithium-ion batteries. 25 The production of ultrathin electrospun bers of CA has been reported in the literature as an important tool for different applications.…”

“…After a steady period, the samples reached the initial degradation temperature ( T 0 ) and started to decompose. During this period, the mass was lost dramatically owing to the depolymerization of polymer materials, dehydration, and decomposition of the cellulose glycosides structure 21 . T 0 of ACC membrane was a little lower than that of neat cellulose membrane due to sulfate groups linked on CNW.…”

“…CNW had been prepared from a crowd of natural sources including wood, 14,15 cotton, 5,16–18 microcrystalline cellulose, 19–22 bacterial cellulose, 23 agriculture residues, 24–29 and sea animals 30,31 . Owning to the high strength and the high specific surface area, CNW was often used as reinforcement in nanocomposites 3 .…”

All‐cellulose composite (ACC) membranes were prepared with cellulose and cellulose nano whisker (CNW) extracted from corn stalk by using NaOH/thiourea as solvent. CNW was isolated via acid hydrolysis method and the yield, size distribution and morphology of CNW were investigated. ACC Membranes were characterized via SEM, XRD, TGA as well as water flux and were further plasticized with glycerol aqueous solution. The mechanical property and transparency of ACC membranes before and after plasticization were compared. CNW prepared with 63% sulfuric acid for 60 min of hydrolysis time had the biggest ratio of length to diameter and moderate yield. ACC membrane with 5% CNW content had the highest tensile strength and the structure of ACC membranes was observed clearly in SEM images. TGA testing indicated that the initial degradation temperature tended to lower after CNW was introduced into membrane. ACC membrane had good optical transmittance and good flexibility after plasticization.

“…Cellulose acetate (CA), as an environmentally friendly material with extensive sources and biodegradability, is widely used in biological separation, desalination, and treatment of different water due to its good biocompatibility, nontoxic, good processability, easy to form membrane, excellent hydrophilicity, and large flux 14–16 . The blend film of PVC and CA can be prepared by solution casting and phase transformation method 17–20 .…”

Based on the hydrophilicity and biodegradability of cellulose acetate (CA), polyvinyl chloride (PVC)/CA blend membrane was prepared by solution comixing and phase transformation method. Then the CA in the blend membrane was partially hydrolyzed under acidic conditions to improve the hydrophilicity of the blend membrane, so as to improve the filtration performance of the PVC/CA blend membrane. The properties of the membranes were systematically characterized by Fourier transform infrared spectroscopy, differential scanning calorimeter, and scanning electron microscopy (SEM). The porosity, water contact angle, pure water flux (PWF), protein retention rate, and mechanical properties of the membrane were measured, and the effect of hydrolysis on the filtration performance of the blend membrane was analyzed.
