Preparation And Characterization For Titanium Dioxide/Dual-Core Phthalocyanine Composite Solar Energy Selective Absorption Coatings

First preparation of dual-core phthalocyanine and several other metal phthalocyanine, infrared spectrum analysis and ultraviolet spectrum analysistest on these phthalocyanine.All the phthalocyanine were characterized by infrared spectrum analysis and ultraviolet spectrum analysis.Study found that, compared with the general metal phthalocyanine,the dual-core phthalocyanine’s Q absorption moves to visible light area.This change make dual-core phthalocyanine in visible light area has a strong absorption.The experiment, it is also to dual-core phthalocyanine coating was studied, the results showed that in the visible region have coating absorption, but absorption the ultraviolet light is not strong.Preparation of titanium dioxide thin film, and research the basic performance.Proof that the titanium dioxide thin film ultraviolet absorption and reflection are very good.Preparation and characterization of titanium dioxide/dual-core phthalocyanine composite solar energy selective absorption coatings.Study found that titanium dioxide thin film can be a very good play a part in reflection ultraviolet (uv) light, protect the inner phthalocyanine coating role.
