Fabrication of cellulose-based polymer electrolyte membrane with green solvent DMSO via N-TIPS technique

fabrication of cellulose –silk composite in liquid phase with green solvent

in this research, cellulose-silk composites production in liquid phase was studied. in this respect,bmimcl ionic liquid was synthesized in the laboratory and was used for dissolution purpose. afterdissolution of the biopolymers and mixing them in the liquid phase, obtained suspension was spread ina petri dish. then, the composite gel was washed with running methanol to remove the il, cellulosea...

Central composite experimental design applied to fabrication of LLDPE microporous membrane via thermally induced phase separation (TIPS) method

Fabrication of Nanocomposite Membrane via Combined Electrospinning and Casting Technique for Direct Methanol Fuel Cell

Emergence of nanotechnology has resulted in the introduction of the electrospinning process in fabricating and characterising the polymer electrolyte membrane from the sulfonated poly (ether ether ketone) (SPEEK) nanocomposite membrane comprised of electrospun Cloisite15A® (e-spun CL...

Fabrication of stable photovoltachromic cells using a solvent-free hybrid polymer electrolyte.

In this work, photovoltachromic cells (PVCCs) are fabricated using a solvent-free polyethylene glycol (PEG)-titanium hybrid polymer electrolyte. With appropriate addition of 1,2-dimethyl-3-propylimidazolium iodide in the electrolyte, the range of tunable colored-state transmittance of the PVCC is enlarged due to an improved fill factor. A transmittance modulation larger than 40% can be maintain...

Modification of Cellulose with Succinic Anhydride in TBAA/DMSO Mixed Solvent under Catalyst-Free Conditions

Homogeneous modification of cellulose with succinic anhydride was performed using tetrabutylammonium acetate (TBAA)/dimethyl sulfoxide (DMSO) mixed solvent. The molar ratio of succinic anhydride (SA) to free hydroxyl groups in the anhydroglucose units (AGU), TBAA dosage, reaction temperature, and reaction time were investigated. The highest degree of substitution (DS) value of 1.191 was obtaine...
