The invention discloses a preparation method of a high-quality
chemical plating layer for the surface of a
polymer substrate. The preparation method comprises the following steps that (1),
polyvinyl alcohol,
silane, ethyl
alcohol and deionized water are put into a dispersing
machine and stirred for 60 min in a constant-temperature water bath at 60 DEG C, an
ammonium dihydrogen
phosphate aqueous solution is added, stirring continues being conducted for 60 min, a 30% catalyst
ionic solution is added, and stirring continues being conducted for 1-60 min; (2), the solution is stirred at the rotation speed of 5,000-10,000 r / min, and a 1% emulsifying agent is gradually added while stirring is conducted; (3), an organic-inorganic
hybrid solution is selectively printed on the surface of the polymersubstrate, the
polymer substrate is dried for 5-10 min under the condition with the temperature of 80-150 DEG C, and a substrate is obtained; (4), the substrate is immersed into a
chemical plating solution for plating,
chemical plating is conducted for 1-60 min at the temperature of 60-100 DEG C, and then
drying is conducted for 1-30 min at the temperature of 40-100 DEG C. The preparation methodhas the beneficial effects that selective chemical plating can be conducted on different
polymer substrates, and the high-quality chemical plating layer with the high
adhesive force and precision canbe obtained.
