Abstract

Layered titanate H_1.07Ti_1.73O₄ was exfoliated into nano-sheet by reacting with n-propylamine solution. The H_1.07Ti_1.73O₄ thin film with preferred or ientation can be obtained by dipping a metal substrate in the nano-sheet sol solution and dry. The titanate thin film can topotactically transformed to a titanium oxide thin film with preferred orientation by heat-treatment, and to a BaTiO₃ thin film with preferred orientation by hydrothermal treatment in a Ba(OH)₂ solution.
