Abstract

The invention relates to a phthalocyanine / TiO2 ordered film and a preparation method thereof, belonging to the field of nonlinear optical films. The invention overcomes the defects of complex equipment, high cost, difficult operation and difficult control of film thickness in the existing method for preparing nonlinear optical films. The phthalocyanine / TiO2 ordered film of the invention is formedby connecting a substrate, a connection layer and a lamination layer from bottom to top, wherein the connection layer is formed by alternately stacking PDDA layers and PSS layers in pairs, and the lamination layer is formed by alternately stacking TiO2 / PDDA layers and phthalocyanine layers. The preparation method comprises the following steps: pretreating the substrate; alternately soaking the substrate in a PDDA solution and a PSS solution; and then, alternately soaking the substrate in a TiO2 compound solution and a phthalocyanine solution to obtain the phthalocyanine / TiO2 ordered film. Theinvention has the advantages of simple and convenient operation of the method, simple equipment, controllable film thickness, better stability, high preparation speed and strong operability and can be used for industrialized production. The invention is applied to the fields of nano-structure films, photoelectric devices, surface engineering, sensors and the like.

Description

technical field [0001] The invention relates to a nonlinear optical film and a preparation method thereof, in particular to a phthalocyanine / TiO 2 Ordered thin films and methods for their preparation. Background technique [0002] The form of a material has a very important impact on its physical and chemical properties. For the same material in different forms, the properties may also be quite different. Thin film materials generally refer to a thin layer of material attached to the surface of the substrate by a certain method. Thin film technology is an important way to realize the practical application of chemical materials, and it is also an effective means to prepare micro-devices. Now thin film technology has penetrated into various fields, such as aerospace, medical, energy and communication. In the future development, thin film materials will develop in the direction of comprehensive, compound, intelligent, energy-saving and environment-friendly. [0003] There a...
