Method for simultaneously improving strength and plasticity of silicon nanoparticles and modified silicon nanoparticles

The invention belongs to the field of inorganic semiconductor materials, and particularly relates to a method for simultaneously improving the strength and plasticity of silicon nanoparticles and modified silicon nanoparticles. The method for simultaneously improving the strength and plasticity of the silicon nanoparticles comprises the step of calcining the silicon nanoparticles at high temperature. According to the method for simultaneously improving the strength and plasticity of the silicon nanoparticles, direct high-temperature calcination can be carried out in an air atmosphere under normal pressure, the process is simple and easy to control, and large-scale production is facilitated. And the thickness of the amorphous oxide film of the modified silicon nanoparticles is controllable, the strength and plasticity of the amorphous oxide film can be further regulated and controlled as required, and tests and calculation show that the plasticity is maximally improved by about 5 times, the strength is improve
