Control of the morphology of cellulose acetate nanofibers via ...
2018年3月22日 · The morphologies of cellulose acetate (CA) nanofibers were studied in relation to various factors, i.e., the composition of the solvent; the concentration of the polymer; and the solubility of the solvent and the polymer. Also, we incorporated polyvinylpyrrolidone (PVP) in the CA nanofibers to modulate the morphology to some extent.
Morphology and water flux of produced cellulose acetate …
2021年2月15日 · Cellulose acetate (CA) ultrafiltration membranes were successfully prepared using the non-solvent induced phase separation (NIPS) methodology. This technique is used to produce porous membranes for a large variety of applications.
The structure and properties of cellulose acetate materials: A ...
2013年2月19日 · Scanning electron microscopy, X-ray diffraction and thermal analysis were used to characterize the morphology, inner structure and thermal behavior of electrospun CA membrane, casted CA film as well as original CA powder. In addition, the pore size distribution and surface hydrophilicity of electrospun membrane and casted film were tested.
Cellulose acetate (CA) is one of cellulose derivative materials for membrane production. CA was one of the first polymers used in aqueous membranes, dating back to the invention of the Loeb-Sourirajan asymmetric membrane in the 1950s [6].
Preparation and Characterization of Porous Cellulose Acetate
2023年6月13日 · The XRD results show that the nanofibrous morphology of cellulose acetate hydrogels is caused by the deacetylation reaction of cellulose acetate. The currently reported methods for preparing cellulose acetate hydrogels use chemical reagents as cross-linking agents, and the prepared ones are non-porous structured cellulose acetate hydrogels.
