Abstract

The invention discloses a reparation method of a copper sulfide nanowire, relating to a copper sulfide nanomaterial. The preparation method comprises the following steps: putting CuCl2.2H2O and oleylamine into a three-necked bottle, and under the protection of N2 atmosphere, heating and maintaining constant temperature, so that CuCl2.2H2O is entirely dissolved in oleylamine to obtain a solution A; dissolving (C2H5)2NCSSNa.3H2O into oleylamine to obtain a solution B; adding the solution B into the solution A for reacting, to obtain a copper sulfide solution with hydrophobic property, then performing centrifugal separation, washing with cyclohexane, then dissolving chloroform to obtain a hydrophobic nano copper sulfide product; mixing and stirring the obtained hydrophobic nano copper sulfide product together with polyethylene glycol monoethylether 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE-PEG) and chloroform, putting the obtained product into a rotary evaporator, then performing vacuum drying and rotary drying, dispersing into H2O, to obtain the copper sulfide nanowire.

Description

technical field [0001] The invention relates to a copper sulfide nanometer material, in particular to a method for preparing a copper sulfide nanowire by a solvothermal method. Background technique [0002] With the development of nanotechnology in the 21st century, inorganic nanomaterials have attracted more and more people's attention due to their unique properties and wide application prospects, and have become a research hotspot today. As an extremely important P-type semiconductor material, copper sulfide nanomaterials are widely used in catalysis, solar cells, polymer surface conductive layers, optical filters and sensing (J.S.Chung, and H.J.Sohn, Electrochemical behaviors of CuS as a cathode material for lithium secondary batteries[J].J Power Sources,2002,108,226-231; Fei Li,Wentuan Bi,Tao Kong,and Qinghua Qin,Optical,photocatalytic properties of novel CuS nanoplate-based architectures synthesized by a solvothermal route [J].
