Preparation and Characterizations of Triethoxysilane-endcapped PEO-PPO-PEO Triblock Copolymers for All-Solid State Supercapacitor . |
| 초록 |
A series of triethoxysilane-endcapped PEO-PPO-PEO triblock copolymers (PL-TESs) was synthesized and utilized as the precursor of polymer electrolyte membranes for all-solid state supercapacitor applications. Various PL-TESs with different molecular weights and PEO compositions were prepared by reacting terminal hydroxyl groups of the corresponding Pluronic® copolymers with (3-isocyanatopropyl)triethoxysilane. Then crosslinked, but transparent and flexible membranes with various contents of ionic liquid could be prepared by a solution casting technique accompanying an in-situ sol-gel reaction between terminal ethoxy silane groups. The prepared membranes were characterized for their structural, mechanical stability, thermal stability, and ionic conductivity. All-solid state supercapacitor cells were assembled and their electrochemical performances were evaluated. |
