Abstract

The invention discloses a preparation method of titanium dioxide and Prussian blue orderly assembled mesogenic nanomaterials. A novel flower-like mesogenic nanomaterial composed of nanowire arrays is prepared by a hydrothermal method; potassium ferrocyanide and titanium sulfate As raw material, PVP as stabilizer, dilute hydrochloric acid as solvent, react under specific temperature conditions to prepare monodisperse, high-purity flower-like titanium dioxide and Prussian blue composite material (TiO 2 ‑PB), the preparation process is simple, the design principle is reliable, the production cost is low, the cycle is short, the application environment is friendly, the prepared composite material has good monodispersity, high purity, uniform shape, and has broad application prospects in many aspects . The solid film constructed by the composite material can be conveniently applied to the surface of conventional paper to produce inkless photoprintable rewritable paper with the same feel and appearance. The production of the composite material and the solid film is simple, and the optical printing method is simple, environmentally friendly, safe and efficient.

Description

technical field [0001] The invention belongs to the field of material technology, and in particular relates to a one-step synthesized titanium dioxide and Prussian blue ordered assembled mesogenic nanomaterial and a preparation method thereof. Background technique [0002] Metal-organic frameworks (MOFs) and inorganic nanocrystals (INCs) are both powerful materials that can help alleviate the energy crisis and solve environmental problems. Some examples of successfully assembling complementary functions of MOFs and INCSs provide good references for the design of new materials, for example, TiO grown in the pores of MIL-101 2 NCs yield a new catalyst that utilizes TiO 2 Synergy between MOFs and MOFs to promote photocatalytic reduction of CO 2 , while generating O 2 . [0003] However, the self-assembly of MOF-INCs with defined crystallographic orientations has not yet been accomplished. MOFs and INCs have different lattice parameters and synthesis methods. Because the ...
