Embodiment 1

[0017] 0.2496g CuSO 4 ·5H 2 O was dissolved in 100ml of distilled water, then 0.01g of PMAA was added, stirred at room temperature for 30min until completely dissolved, and then the solution was placed in a vacuum oven at 80°C for 2h. The solution was removed, and 0.076 g of CH was added to it 4 N 2 S, after stirring for 10 min, the solution was placed in a vacuum oven at 80° C. for 24 h, and cooled to room temperature. After the reaction product was separated by centrifugation, it was repeatedly washed with deionized water and absolute ethanol, and finally dried under vacuum at 60°C for 12 hours to obtain a black product.

[0018] figure 1 XRD patterns of CuS microwires synthesized by template method. from figure 1 It can be seen that all the XRD peak positions in the figure are consistent with the standard diffraction pattern (JCPDS No.0620464), and there are no other miscellaneous peaks, indicating that the reaction product is pure CuS hexagonal crystal without Cu 2 ...

Abstract

The invention relates to the manufacturing of a nano or micro-material, in particular to a preparation method of a copper sulfide ultra-long micro-wire. The method sequentially comprises the following steps of: a, using CuSO4.5H2O as a raw material, dissolving CuSO4.5H2O in de-ionized water, then adding a polymer template, stirring at a room temperature until the polymer template is dissolved completely; b, placing the solution into a vacuum drying oven, and carrying out heat preservation at 60-80 DEG C; c, taking out the solution, adding CH4N2S for reaction; and d, placing the solution into the vacuum drying oven after stirring, carrying out heat preservation at 60-120 DEG C, cooling to room temperature; and centrifugally separating the product, then respectively washing with de-ionized water and absolute ethanol, and finally drying under vacuum conditions and at 60 DEG C to obtain the end product. According to the preparation method of a copper sulfide ultra-long micro-wire, a chemical liquid-phase synthesis method is employed, the polymer template is introduced, the process step is simplified, the cost is low, and the yield is high, therefore, the particle size and morphology of CuS can be controlled, the environmental pollution is low, and the green synthesis can be implemented.

Description

technical field [0001] The invention relates to a nano or micro structure material manufacturing, in particular to a preparation method of copper sulfide ultra-long micro wires. Background technique [0002] Copper sulfide is an important transition metal sulfide, which has good catalytic activity, visible light absorption, photoluminescence, third-order nonlinear polarizability and third-order nonlinear response speed, and is widely used in solar cells, photoelectric conversion, etc. Switches, gas sensors and other fields. Nano- or micron-scale CuS materials are widely used in photonic crystals, catalysis, and controlled-release drug encapsulation capsules due to their special structures such as low density and large specific surface, so they have good application prospects. [0003] In recent years, the controllable morphology synthesis of CuS has also attracted widespread attention, and its preparation methods mainly include microemulsion method, vesicle method, electroc...
