Embodiment 1
[0041] Embodiment 1 Conductive silicon ball and preparation method thereof
[0042] The concrete steps of preparation method are as follows:
[0043] 1. Surface modification of silicon spheres: 4gSiO 2 Evenly disperse the silicon spheres into 20ml of silane coupling agent, and keep stirring for 12 hours, so that the surface of the silicon spheres is connected with active groups and is easy to connect with the metal;
[0044] 2. Preparation of metal sol solution: Add 0.1 mol / L potassium borohydride aqueous solution dropwise in 250 L of chloroauric acid solution with a concentration of 2.5 mol / L until the solution turns pink to obtain gold sol solution;
[0045] 3. Add the surface-modified silicon spheres in step 1 to the metal sol solution in step 2, and continue stirring for 12 hours to obtain metal-functionalized silicon spheres, which are refrigerated at 5°C for later use;
