[0022] A method for preparing a submicron-scale or micron-scale monodisperse single crystal conductive gold ball, which can include the following steps:
[0023] Step A, adding chloroauric acid, polydiallyldimethylammonium chloride and silver nitrate with a molecular weight of 100000~200000 to the ethylene glycol solution, so that the concentration of chloroauric acid in the mixed liquid is 0.0005~0.002mol / L, the concentration of polydiallyl dimethyl ammonium chloride is 0.01-2 mol / L, and the reaction is carried out at 180-200 ° C for 1-2 hours, so as to obtain small-sized monodisperse single crystal conductive gold sphere colloid A solution (for example: the small-sized single-crystal conductive gold sphere colloidal solution can be a 100-nanometer single-crystal conductive gold sphere colloidal solution). Step B is performed with the small-sized monodisperse single crystal conductive gold sphere colloidal solution as the seed solution.

[0035] Example 1
[0036] like Figure 5 As shown, a submicron-scale monodisperse single crystal conductive gold ball, the preparation method of which includes the following steps:
[0037] Step a1, add chloroauric acid, silver nitrate and polydiallyl dimethyl ammonium chloride (Mw=100000~200000, 20wt%) with a molecular weight of 100000~200000 into 100 ml of ethylene glycol solution, after mixing The concentration of chloroauric acid in the liquid is 0.001 mol / L, the concentration of silver nitrate is 0.01 mmol / L, the concentration of polydiallyldimethylammonium chloride is 0.025 mol / L, and then the oil bath at 200 °C Heating and reacting in a pot for 2 hours, and cooling to room temperature naturally, thereby preparing a 100-nanometer monodisperse single crystal conductive gold sphere colloidal solution.
[0038] Step b1, using the 100-nanometer monodisperse single crystal conductive gold sphere colloidal solution obtained in step a1 as the seed solution, adding chloroauric...
