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.
