[0073] The preparation method of the ink composition according to the present invention is not particularly limited, as long as the doped tin oxide can be uniformly mixed with the binder and optional solvents and additives. For example, the ink composition according to the present invention can be obtained by uniformly mixing the doped tin oxide with the binder and optional solvents and additives in a mixer (such as a planetary ball mill). The methods and conditions for uniformly mixing the components in a mixer are well known in the art and will not be repeated here.
[0074] The ink composition according to the present invention can be applied on the surface of an insulating (i.e., non-conductive) substrate, and electroless plating is performed on the surface of the insulating substrate, so that the surface of the insulating substrate can be selectively Metalization.
[0075] According to a sixth aspect of the present invention, the present invention provides a method for s...
Embodiment 1
[0099] (1) SnO 2 placed in the ball mill tank of the ball mill, and then added Nb 2 o 5 and ethanol for 2 hours of trituration. Wherein, relative to 100 parts by weight of solid matter, the consumption of ethanol is 250 parts by weight; 2 and Nb 2 o 5 The total amount is the benchmark, Nb 2 o 5 The dosage is 10% by weight. The mixture obtained by ball milling was dried in an air atmosphere at 60° C. for 3 hours to obtain a powder mixture with a volume average particle diameter of 1.5 μm. The powder mixture was calcined at 1050°C in an air atmosphere for 5 hours, and the calcined product was ground to a volume average particle size of 1.2 μm to obtain doped tin oxide, its color coordinates in CIELAB color space and light reflection The rates are listed in Table 1.
[0100] (2) Add the doped tin oxide and antioxidant 1010 obtained in step (1) into polyhexamethylene terephthalamide PA6T, after mixing uniformly, the resulting mixture is sent into an extruder, and Extrusi...
Embodiment 2
[0127] (1) The same method as in Example 1 was used to prepare doped tin oxide.
[0128] (2) The polymer plate was prepared by the same method as in Example 1, except that, relative to 100 parts by weight of polyhexamethylene terephthalamide PA6T, the content of doped tin oxide was 3 parts by weight. The color coordinates of the polymer sheets in the CIELAB color space are listed in Table 1.
[0129] (3) Using the same method as in step (3) of Example 1, irradiate the surface of the polymer plate obtained in step (2) with laser light.
[0130] (4) Using the same method as in step (4) of Example 1, the polymer plate obtained in step (3) was placed in a plating solution for electroless plating to form a metal plating layer of an antenna pattern.
[0131] Through visual inspection, it was found that the formed metal layer was continuous and complete, and there was no missing plating. The plating speed and adhesion of the metal layer are listed in Table 1.
