通过对多孔氧化铝膜与二氧化钛/聚合物纳米复合薄膜进行完整且纳米级精确的形态复制，合成了新型纳米管二氧化钛/聚合物复合材料。所得二氧化钛/聚合物纳米复合管材具有物理柔性，可被视为一种新型软物质。乳胶胶体微球被封装到所得纳米管中，形成独特的独立式“微豆荚”胶体组件。通过低温氧等离子体处理从纳米复合管中去除聚合物成分，产生具有多孔壁的二氧化钛纳米管。所得的中孔随后被用作纳米反应器，用于化学形成金纳米颗粒，从而得到新型的纳米结构、颗粒壁纳米管杂化物。本文演示的纳米结构通常适用于各种陶瓷-聚合物复合纳米管和纳米粒子-纳米管杂化物的合成。
Novel nanotubular titania/polymer composite materials are synthesized via complete and nanometer-precise morphological replication of a porous alumina membrane with titania/polymer nanocomposite thin films. The obtained titania/polymer nanocomposite tubing is physically flexible, and can be seen as a new type of soft matter. Latex colloidal microspheres are encapsulated into the resultant nanotubing to form a unique free-standing ‘micro-beanpod’ colloidal assembly. Removal of the polymer components from the nanocomposite tubings by low-temperature oxygen plasma treatment yields titania nanotubes with porous walls. The resulting mesopores are subsequently employed as a nanoreactor for the chemical formation of gold nanoparticles to give a novel, nanostructured, particle-in-wall nanotubular hybrid. The nano-architectures demonstrated herein are generally applicable to the syntheses of various ceramic–polymer composite nanotubes and nanoparticle–nanotube hybrids.
