Abstract:
PURPOSE: A block or random type organic-inorganic hybrid copolymer is provided to provide a solid phase polymer electrolyte membrane with excellent mechanical properties and ion conductivity. CONSTITUTION: A block or random type organic-inorganic hybrid copolymer is indicated in chemical formula 1 or 2. A manufacturing method thereof comprises: a step of manufacturing poly(ethylene glycol) methyl ether methacrylate by using reversible addition-fragmentation chain transfer polymerization; a step of mixing the poly(ethylene glycol) methyl ether methacrylate, polyhedral oligomeric silsesquioxane, and azobisisobutyronitrile; and a step of manufacturing the block or random type organic-inorganic hybrid copolymer by using reversible addition-fragmentation chain transfer polymerization.
Abstract:
PURPOSE: An anti-fouling organic/inorganic composite compound is provided to obtain an antifouling membrane having excellent anti-fouling performance, to extend life and reduce maintenance costs of a membrane such as cleaning costs. CONSTITUTION: An anti-fouling organic/inorganic composite compound comprises an anti-fouling organic/inorganic composite compound, a core formed of polyhedral oligomeric silsesquioxane, and an arm connected to at least one Si of the polyhedral oligomeric silsesquioxane. A manufacturing method of an anti-fouling membrane comprises: a step of preparing a solution which comprises the organic/inorganic composite compound and a solvent; a step of forming a surface layer by spreading the solution on the surface of a membrane which requires anti-fouling surface treatment.

Abstract:
본발명은리튬염이함유된리튬이온전도성고분자를전해질로사용하는리튬이온이차전지용고체상고분자전해질막의제조에관한것이다. 스타형고분자의안쪽은고분자사슬의밀도가높고바깥으로갈수록고분자사슬의밀도가작아지게되는데, 이는 PEO계고분자사슬의결정성을낮추고고분자사슬의유동성을향상시키는데도움을주어높은이온전도도를기대할수 있다.
