Abstract

The invention relates to a preparation method of a highly dispersible copper phthalocyanine photoelectric material, belonging to the technical field of new energy sources. At first, that cop phthalocyanine and the dopamine solution are oscillatory reacted, the oscillating filter residue and lecithin are reacted and oxidized with potassium permanganate solution, so that a reaction filter cake is obtained, a surface of the graphene is then pre-modified with ethanol, at last, the modified graphene and the reaction filter cake are reacted in the dimethyl acetamide to finally prepare the highly dispersive copper phthalocyanine photoelectric material. The highly dispersive copper phthalocyanine photoelectric material prepared by the invention has good dispersibility, good photoelectric performance and wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a highly dispersible copper phthalocyanine photoelectric material, which belongs to the technical field of new energy sources. Background technique [0002] Phthalocyanine is a macrocyclic compound with a cavity in the ring. Various metal elements can be accommodated in the cavity to form metal phthalocyanine compounds. The macrocyclic structure of copper phthalocyanine contains four mutually symmetrical nitrogen atoms, which are connected to the copper atom in the middle of the ring, and combine with the nitrogen atom on the ring structure in the form of a coordination bond to form a metal complex. The performance of the metal complex is relatively stable. [0003] It is a P-type semiconductor with a narrow band gap, strong absorption in the visible and ultraviolet regions, and good photoelectric properties. In addition, it has excellent light, heat and stability due to its unique conjugated structur...
