    摘要: The present invention relates to a method for manufacturing composite polymer electrolyte membranes coated with inorganic thin films for fuel cells using a plasma enhanced chemical vapor deposition (PECVD) method or a reactive sputtering method, so as to reduce the crossover of methanol through polymer electrolyte membranes for fuel cells and enhance the performance of the fuel cells. The manufacturing method of composite polymer electrolyte membranes coated with inorganic thin films for fuel cells according to the present invention is characterized to obtain composite membranes by coating the surface of commercial composite polymer electrolyte membranes for fuel cells with inorganic thin films using a PECVD method or a reactive sputtering method. The inorganic materials to form the inorganic thin films are chosen one or more from the group comprising silicon oxide (SiO2), titanium oxide (TiO2), zirconium oxide (ZrO2), zirconium phosphate (Zr(HPO4)2), zeolite, silicalite, and aluminum oxide (Al2O3). The present invention, by coating the polymer electrolyte membranes for fuel cells with inorganic thin films via a PECVD method or a reactive sputtering method, reduces the methanol crossover sizably without seriously reducing the ionic conductivity of polymer electrolyte membranes, thereby, when applied to fuel cells, realizes a high performance of fuel cells.

    摘要: A monomer composition for polymerizing a branch-type silsesquioxane polymer is disclosed. The monomer composition includes hydroxy-substituted cyclic siloxane in a solvent, and the hydroxy-substituted cyclic siloxane includes stereoisomers of cyclic siloxane of cis, trans, random and twist structures at controlled ratios. Also disclosed are a branch-type silsesquioxane polymer synthesized by polymerizing the monomer composition for polymerizing a branch-type silsesquioxane polymer, and a method for synthesizing the same. In accordance with the disclosure, the isomers can be isolated stably at desired ratios. The isolated isomers may be polymerized into polymers of various types. Since the polymers exhibit low dielectric property, they may be utilized as low dielectric materials.

    摘要: The present invention relates to an actuator which is one of the energy conversion devices, and is characterized by improving the ability to convert electrical energy into mechanical energy by way of using a dielectric elastomer composite comprising a filler with an efficient dispersibility. In case of using a conventional resilient dielectric layer, there was a problem in that the operating voltage is high, while advantageously exhibiting a fast response and a high strain. The present invention can provide dielectric elastomer composite actuators that show excellent electromechanical conversion properties, by adding a dispersing agent such as a pyrene derivative or a polymeric compound having an amine end group when preparing the composite wherein carbon-based conductive fillers such as carbon blacks, single-walled carbon nanotubes (SWCNTs), double-walled carbon nanotubes (DWCNTs), multi-walled carbon nanotubes (MWCNTs) and graphenes, or high dielectric fillers such as copper phthalo-cyanine (CuPc), MOFs (metal organic frameworks) and barium titanate (BaTiO3) are comprised in a thermoplastic resilient dielectric layer to enhance the dispersibility of the fillers.
