Here we report the controlled generation of micelle-templated organosilicate nanostructures resulting from self-assembly of a block copolymer/organosilicate mixture followed by organosilicate vitrification and copolymer thermolysis. Variation of solution condition and the copolymer/organosilicate mixture composition generates widely different film morphologies ranging from toroids to linear features to contiguous nanoporous monolayers. The use of reactive organosilicates for block copolymer templation generates functional inorganic nanostructures with thermal and mechanical stability.
在此，我们报告了通过嵌段共聚物/有机硅酸盐混合物的自组装，随后进行有机硅酸盐玻璃化和共聚物热解来可控地生成胶束模板化有机硅酸盐纳米结构。溶液条件和共聚物/有机硅酸盐混合物组成的变化产生了从环形到线性特征再到连续纳米多孔单层的广泛不同的薄膜形态。使用反应性有机硅酸盐进行嵌段共聚物模板化可生成具有热稳定性和机械稳定性的功能性无机纳米结构。
