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. We used mixtures of the solvents dimethylformamide (DMF) and acetone...
In this paper, the cellulose/polyacrylonitrile(PAN) composite nanofibers were prepared via electrospinning technique firstly. Then, cellulose/PAN/Cu nanofibers were fabricated with antibacterial function by loading Cu(II) ions. The morphology, mechanical properties and hydrophilicity of nanofibers was characterized. Antibacterial performance of cellulose/PAN/Cu nanofiber with against Staphylococcus aureus...
We report on an efficient method for extracting cellulose nanofibers with cellulose II crystal structure that presents a relatively high yield (approximately 82%) after mechanical treatment. Delignification technique plays an important role in the conversion of crystals from cellulose I to cellulose II during the mercerization process and in the subsequent fibrillation of cellulose II nanofibers....
In this work, bacterial cellulose/electrospun membrane three-dimensional (BC/ENM 3D) hybrid structures were fabricated using in-situ self-assembly and characterized by SEM and FTIR. SEM showed as the bacterium extrudes cellulose nanofibrils; they gradually self-assemble to form a unified network on membrane surface and also penetrate into its structure, hence securely binding electrospun nanofiber...
To construct a biomimetic scaffold with a nanoscale structure similar to that of natural tissue, the objective of this work was to prepare three-dimensional (3D) porous hybrid scaffolds based on gelatin and bacterial cellulose nanofibers for tissue regeneration. The nanofibrous structure, water absorption, and compressive mechanical properties of the scaffolds were studied. The hybrid scaffolds not...
