The objective of this work was to study the feasibility of preparing cellulose acetate (CA) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. CA solutions in dichloromethane (DCM), formic acid, acetic acid and trifluoroacetic acid (TFA) were electrospun into nonwoven fiber membranes, respectively. The scanning electron microscope (SE...

Abstract Electrospinning is a contemporary and effective technique for producing fine fibers with diameters as small nanometers by using an electric field. These have numerous industrial applications, including filtration, sensors, composite materials, membranes. This study provides overview of the electrospinning process discusses few applications polyvinyl alcohol based electrospun nanofibers...

Barrier membranes that are used for guided tissue regeneration (GTR) therapy usually lack bioactivity and the capability to promote new bone tissue formation. However, the incorporation of an osteogenic agent into polymeric membranes seems to be the most assertive strategy to enhance their regenerative potential. Here, the manufacturing of composite electrospun membranes made of poly (ε-caprola...

Covalent organic frameworks (COFs) show advantageous characteristics, such as an ordered pore structure and a large surface area for gas storage separation, energy storage, catalysis, molecular separation. However, COFs usually exist difficult-to-process powders, preparing continuous, robust, flexible, foldable, rollable COF membranes is still challenge. Herein, with fiber morphology the first ...

Electrospun nanofiber membranes surface functionalized with 3D nanolayers through ATRP provide adsorption capacities over 50-times higher than current commercial membrane adsorption systems and over 12-times higher than packed bed resins; additionally, the adsorption kinetics remain 10-times faster than packed bed resins and have over 15-times higher permeance.
