摘要: Abstract Gels were prepared by 1,3-butanediol diacrylate (BDD) or tetraethylene glycol (TEG) polymerisation (UV irradiation with about 1 wt.% of benzoin methyl ether as initiator) in the presence gamma butyrolactone (BL) BL/LiN(CF 3 SO 2 ) (LiTFSI) solutions which incorporated polymer network. For diacrylate/BL gels, determination molar polarisabilities and Raman spectroscopic study allow to show that there is no specific interaction between solvent polymer. The evolution ionic conductivity gel composition related volumetric fraction liquid phase gel. maximum absorption capacity network towards determined assuming a “cubic-like” structure. In order compare, second part this paper, conductivities “free” phases, simplified model presented for electrolytes. article, focused on BDD/BL/LiTFSI
