Abstract

Solid polymer electrolytes with high ionic conductivity have been prepared from a microphase separated fluorinated copolymer bearing cyclocarbonate side groups.

Polymers Based on Cyclic Carbonates as Trait d'Union Between Polymer Chemistry and Sustainable CO2 Utilization

“…[78] Recently,L iu et al improvedt he synthesis of 2g that, in the past, was affectedb yh omopolymerization and by the presence of colored impurities affecting the stability of 2g. [81] Synthesis and applicationso fm onomer 2i,a so btained either from GD or from GC, are discussed in al ater section, in combination with the preparation of ab iscarbonate (bis-5CC)a nalogue. Fluorinated compound 2h was prepared from 2-(trifluoromethyl)acrylic acid and glycerol and copolymerizedw ith vinylidene fluoride as ap recursor for the preparation of coatings [80] and of solid copolymer electrolytes.…”

“…AmØduri and co-workerss tudied P(VDF-co-2h), which was previously discussed in the section on adhesive coatings, [80] for application in SPEs. [81] Whereas PVDF is widely used in lithium batteries, the authors anticipated that the presence of the highly polar carbonate units of 2h would improvet he mobility of lithium ions. Deeper analysis of the structureo fP (VDF-co-2h)r evealed the inclusion of 28 % 2h in the polymer structure.…”

Synthesis and cationic ring‐opening polymerization of oxetane monomer containing five‐membered cyclic carbonate moiety via highly chemoselective addition of CO2

“…This procedure is used for the synthesis of polymers bearing five‐membered cyclic carbonate moieties . As with the linear aliphatic polycarbonates, the polymers bearing cyclic carbonate can be utilized as functional materials such as crosslinkable polymers, enzyme immobilized films, self‐assembled amphiphilic polymer, molecular imprinting, polymer/smectite nanocomposites, and solid (gel) polymer electrolytes …”

“…68 As with the linear aliphatic polycarbonates, the polymers bearing cyclic carbonate can be utilized as functional materials such as crosslinkable polymers, 70,71 enzyme immobilized films, 72 self-assembled amphiphilic polymer, 73 molecular imprinting, 74 polymer/smectite nanocomposites, 75 and solid (gel) polymer electrolytes. [76][77][78][79][80][81] Herein, we report the synthesis of a novel five-membered cyclic carbonate carrying oxetane monomer via a highly chemoselective ring-expansion addition of epoxy-substituted oxatane monomer with CO 2 by using a catalytic amount of DBU•HI under ordinary pressure and mild conditions as a key step. Then, the obtained monomer with/without commercially available bisoxetane monomer was converted to linear or crosslinked polyoxetane bearing five-membered cyclic carbonate in high yield by cationic ring-opening polymerization using catalytic amount of BF 3 -Et 2 O.…”
