Synthesis and properties of gel polymer electrolyte membranes based on novel comb-like methyl methacrylate copolymers

Proton conducting gel electrolytes based on polymethylmethacrylate doped with sulfuric acid solutions in N,N-dimethylformamide

“…3 the gels conductivity ascends with polymer molecular weight increasing, the viscosity increases simultaneously. Similar results were obtained in [28] for gel electrolyte based on (methyl methacrylatemaleic anhydride) copolymer (P(MMA-MAh) with poly(ethylene glycol) monomethyl ether (PEGME) of different molecular weights, as well as for PMMA gels doped with H 3 PO 4 solutions in DMF [23]. At the same time for gel electrolyte based on PMMA and doped with o-hydroxybenzoic acid solution in dimethylacetamide [5] the contrary results were performed.…”

Graft copolymer electrolytes for high temperature Li-battery applications, using poly(methyl methacrylate) grafted poly(ethylene glycol)methyl ether methacrylate and lithium bis(trifluoromethanesulfonimide)

“…A cross-linked PMMA:PEGMA system was investigated by Elmér et al [12], who observed that the conductivity decreased with increased cross-linking, while Ruzette et al [13] synthesized a PMMA:PEGMA block copolymer with varied salt concentrations. Also a gel polymer electrolyte of P (MMA-MAh):PEGME and propylene carbonate have been synthesized [14], which displayed higher conductivity for longer side chains. Moreover, a system with slightly different backbone monomer, poly(lauryl methacrylate), has been investigated as an SPE host by Soo et al [15].…”

Study on preparation and properties of gel polymer electrolytes based on comb-like copolymer matrix of poly(ethylene glycol) monomethylether grafted carboxylated butadiene-acrylonitrile rubber

“…The cross-linked main chains in comb-like structure provide rigid backbone and endow gel system with high thermal stability and mechanical properties, while the free branched chains, usually oligomeric poly (ethylene glycol) chains with good segmental motion and Li + affinity, can give rise to high ionic conductivity [19]. Researchers have studied some kinds of comb-like copolymers for GPE [19][20][21][22][23][24][25][26], such as methylmethacrylate-maleic anhydride copolymer with oligo-oxyenthylene side chains [21], copolymer of acrylonitrile and poly (ethylene glycol) methyl ether methacrylate [22], poly(methyl methacrylate) grafted poly(vinylidene fluoride-hexafluoropropylene) [23]. GPE based on copolymer of butadiene-acrylonitrile rubber (NBR) and poly (ethylene glycol) methyl ether methacrylate were also studied [24], as well as the Li + interaction with ether and nitrile groups [22,27].…”
