Multilayered mesoporous titanate nanocomposite film: Fabrication by layer-by-layer self-assembly and its electrochemical properties with H+ intercalation

A novel multi-layer film consisting of mesoporous titanate nanocomposite (MT) and poly(amine) was fabricated by the layer-by-layer (LBL) self-assembly strategy. UV–vis spectroscopy and atomic force spectroscopy show that a regular growth and spread of the MT/poly(amine) layers on the substrates. Cyclic voltammetry indicates that the titanate nanochannel layers in the mesoporous nanocomposite film are electroactive and demonstrate strong H+ intercalation property.
