    • PURPOSE: A proton-conducting polymer nanocomposite film has excellent proton conductivity even at high temperatures and has excellent mechanical strength superior than conventional PEMFC fluorine-based polymer film. CONSTITUTION: A proton-conducting polymer nanocomposite film is that a sulfonate group-introduced silsesquioxane is mixed to a proton-conducting polymer substrate. A manufacturing method of the proton-conducting polymer nanocomposite film comprises a step of dissolving a fluorine-based proton-conducting polymer substrate into a solvent; a step of dissolving a sulfonate-introduced silsesquioxane into a solvent; a step of mixing the fluorine-based polymer substrate solution and the silsesquioxane solution; a step of ultrasonic waves-treating the mixed solution and dispersing silsesquioxane in the fluorine-based polymer; and a step of carrying out a casting in a vacuum oven and removing residues.

    • A reactive porogen based on organic noncyclic-polyol, and ultra-low dielectric materials prepared by using the same porogen are provided not to remain carbon residue after semiconductor-manufacturing process, and produce ultra-low dielectric materials having enhanced mechanical properties based on the same porosity and small size of pores, so that the ultra-low dielectric materials are useful as interlayer insulating film of next generation semiconductor for copper wiring. The reactive porogen is prepared by replacing the terminal hydroxy group of organic noncyclic-polyol by alkylalkoxysilane, wherein the organic noncyclic-polyol is completely pyrolyzed at 350-500 deg.C not to remain carbon residue; and the organic noncyclic-polyol is erythritol represented by the formula(1): (HOH2C)3C-CH2-OR or petaerythritol organic compound represented by the formula(2): HOCH2[CH(OH)]nCH2OH, wherein R is H, CH2C(CH2OH)3 or CH2C(CH2OH)2CH2OCH2C(CH2OH3), and n is an integer from 2 to 4. The ultra-low dielectric material composition comprises 10-90 volume% of organic or inorganic silicate precursor as an organic silicate matrix and 10-90 volume% of the porogen as a porogenic template, wherein the matrix is polymethylsilsesquioxane monopolymer or copolymer. The ultra-low dielectric materials are prepared by preparing a thin layer with the ultra-low dielectric material composition, and sol-gel reacting and heat-treating the thin layer.
