Preparation of ion-track membranes of poly(p-phenylene terephthalamide)
There have been numerous studies on ion-track membranes of poly(ethylene terephthalate) (PET) and polycarbonate (PC), which are easily prepared by ion beam irradiation and subsequent alkaline etching. More importantly, the ion-track membranes of chemically and thermally stable polyimide (PI) and polyamide (PA), with controlled pore shape and size, may be required for the design of materials tha...
متن کاملAcid-Functionalized Mesostructured Aluminosilica for Hydrophilic Proton Conduction Membranes
New proton exchange membrane (PEM) materials with high proton conductivities at elevated temperatures (ca. > 150 °C) offer the promise of improving PEM fuel cell operation. Higher operating temperatures would provide several benefits including: (i) improved resistance to carbon monoxide poisoning of the platinum (Pt) electrocatalyst at the anode, (ii) reduced need for feed-stream heat and humid...
متن کاملEngineering hydrophilic conducting composites with enhanced ion mobility.
Ion mobility has a direct influence on the performance of conducting polymers in a number of applications as it dictates the operational speed of the devices. We report here the enhanced ion mobility of poly(3,4-ethylene dioxythiophene) after incorporation of gelatin. The gelatin-rich domains were seen to provide an ion pathway through the composites.
متن کاملVoltage increase of aqueous lithium-ion batteries by Li-ion conducting Li1.5Al0.5Ge1.5(PO4)3 glass-ceramic
In this research, a lithium ion conducting lithium aluminum germanium phosphate (LAGP) glass-ceramic with a formula of Li1.5Al0.5Ge1.5(PO4)3 was synthesized by melt-quenching method and subsequent crystallization at 850 °C for 8 h. The prepared glass-ceramic was characterized using X-ray diffraction analysis (XRD) and field emission scanning electron microscopy (FESEM). The XRD patterns exhib...
متن کاملA novel poly(2,6-dimethyl-1,4-phenylene oxide) with trifunctional ammonium moieties for alkaline anion exchange membranes.
2,4,6-Tri(dimethylaminomethyl)-phenol was synthesized as a trifunctional moiety and incorporated onto poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) to obtain a novel quaternary ammonium functionalized PPO (PPO-TQA). Membranes of the polymer were fabricated and exhibited high conductivity, a low swelling ratio and water uptake.
