Microporous Cyclodextrin Film with Funnel?type Channel Polymerized on Electrospun Cellulose Acetate Membrane as Separators for Strong Trapping Polysulfides and Boosting Charging in Lithium–Sulfur Batteries

Studies of Electrospun Cellulose Acetate Nanofibrous Membranes

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...

Pebax-Modified Cellulose Acetate Membrane for CO2/N2 Separation

Carbon dioxide (CO2) release from the exhaust gas streams of power plants that burn fossil fuels contributes the most emission of this gas, which includes more than half of the greenhouse effects. Thus, the separation of CO2 from exhaust gases is one of the main environmental concerns. Membrane technology, due to many advantages, has attracted many research attentions among the various gas sepa...

Application of Genetic Programming as a Powerful Tool for Modeling of Cellulose Acetate Membrane Preparation

Functional membrane separators for next-generation high-energy rechargeable batteries

Themembrane separator is a key component in a liquid-electrolyte battery for electrically separating the cathode and the anode, meanwhile ensuring ionic transport between them. Besides these basic requirements, endowing the separator with specific beneficial functions is now being paid great attention because it provides an important alternative approach for the development of batteries, partic...

Fabrication of cellulose acetate/polybenzoxazine cross-linked electrospun nanofibrous membrane for water treatment.

Herein, polybenzoxazine based cross-linked cellulose acetate nanofibrous membrane exhibiting enhanced thermal/mechanical properties and improved adsorption efficiency was successfully produced via electrospinning and thermal curing. Initially, suitable solution composition was determined by varying the amount of the benzoxazine (BA-a) resin, cellulose acetate (CA) and citric acid (CTR) to obtai...
