Abstract:
PURPOSE: Disclosed is a polymer gel electrolyte in which cellulosic polymers with high hygroscopic of an electrolyte is blended in polymer matrix, so as to suppress the leakage of the electrolyte and to increase portability of lithium ions. CONSTITUTION: A polymer gel electrolyte comprises a polymer solution mixed with hygroscopic polymer selected from a vinylidene fluoride// hexafluoro propylene and cellulose based group and electrolyte, in which lithium salt is dissolved in an aprotic solvent as 0.5-1.5M. The lithium salt is selected from a group of lithium salt accommodating lithium hexafluorophosphate (LiPF6), lithium perchlorate(LiClO4), lithium trifluoromethanesulfonate (LiCF3SO3), lithium tetrafluoroborate (LiBF4) or their mixtures.

PURPOSE: A self-photo initiating silicon acrylate resin composition is provided to have excellent surface physical properties and hardening rate by remarkably improving hardening reactivity of a self-photo initiating resin. CONSTITUTION: A UV-curable resin composition comprises: 1-10 weight% of self-photo initiating silicone acrylate resin; 20-70 weight% of one or more oligomers selected from polyester acrylate, urethane acrylate, epoxy acrylate, silicon acrylate, and a mixture thereof; 20-70 weight% of acrylic monomer, and 5-30 weight% of polyfunctional mercaptane. A manufacturing method of the self-photo initiating silicon acrylate resin comprises: a step of mixing a polyfunctional silicon acrylate Michael acceptor and a beta-dicarbonyl Michael donor with an organic solvent in a molar ratio of 0.05-3:1; and a step of conducting a Michael donor addition reaction under the presence of strong acid.
