A novel end-group crosslinked anion exchange membrane showed the connecting ionic-clustered morphology that improved electrochemical performances and durability for alkaline fuel cell operation.
We compared experimental and simulated data to investigate the phase separation water channel formation of proton exchange membranes (PEMs) for fuel cell. Sulfonated block copolyimides (SPIs) were adopted as model polymers experiments simulations, Nafion was used a reference. SPIs observed have different microscopic structures such constituent atoms, backbone rigidity, locations sulfonic acid groups, all which significantly affect phenomenological properties at macroscopic level density,...
Several in-situ preparation methods of gel polymer electrolytes (GPEs) to develop long-lasting and safe lithium ion batteries (LIBs) recently have been reported. However, the reported still technical gaps for practical industrial uses in terms processing time, integrity with current production line, scalability. Here, we report an method prepare crosslinked poly(vinylene carbonate-co-cyanoethyl acrylate) (PVCEA) GPEs using 10 MeV electron beam (EB) irradiation a fully-assembled metallic...
In this study, we developed an efficient method to prepare a crosslinked poly(vinyl pyrrolidone)/poly(ethylene glycol) diacrylate) (PVP/PEGDA) copolymer-grafted non-woven polypropylene (PP) sheet for which water can be used as green solvent while providing large amount of grafting functional groups on the PP matrix without diminishing mechanical properties. It was demonstrated that subsequent iodine complexation PP-g-PVP/PEGDA produces strong antibacterial activity desirable wound dressings....
In this study, we demonstrated that the enhanced performance of poly(acrylic acid) binder-based silicon/graphite composite anode (c-PAA-Si/C) can be achieved by a quick, scalable, and solid-state electron beam irradiation-induced crosslinking in presence methylenebisacrylamide (MBA) as water-soluble crosslinker. The result from analysis an irradiated PAA binder film revealed was completely crosslinked irradiation at absorbed dose 30 kGy 10 wt% MBA, thereby leading to much reduced swelling...
In this research, we report an initiator-free and room-temperature 2.5 MeV electron beam (EB)-induced gelation strategy to in-situ create polyvinylpyrrolidone-based gel polymer electrolytes (PVP-GPEs) in a fully-assembled lithium ion battery (LIB). A radiation-sensitive liquid precursor consisting of 1-vinyl-2-pyrrolidone (VP), poly (ethylene glycol) diacrylate (PD), LiClO4 electrolyte (LE) was effectively converted freestanding PVP-GPEs even at absorbed dose 2 kGy (Irradiation time 6 s)....
