Ordered Bicontinuous Nanoporous and Nanorelief Ceramic Films from Self Assembling Polymer Precursors

摘要

Three-dimensional ceramic nanostructured films were produced from silicon- containing triblock copolymer films exhibiting the double gyroid and inverse double gyroid morphologies (space group Ia3d). A one-step room-temperature oxidation process that used ozonolysis and ultraviolet irradiation effected both the selective removal of the hydrocarbon block and the conversion of the siliconcontaining block to a silicon oxycarbide ceramic stable to 400 deg.
