preparation example Construction

[0056] According to a third aspect of the present invention, the present invention also provides a method for preparing a polymer product, the method comprising the following steps:

[0057] S1, A metal element source, strontium source, and M metal element source are mixed, and the obtained solid mixture is roasted in a roasting furnace at 800-1100°C for 2-20 hours to obtain a metal compound,

[0058] S2. Mix the polymer matrix component with the metal compound, and shape the obtained mixture.

[0059] According to the method described in the third aspect of the present invention, A is one or more than two selected from the group consisting of La, Pr, Nd, Pm, Sm, Eu, Gd and Dy, and M is Co and / or Mn .

[0060] According to the method described in the third aspect of the present invention, in terms of elements, the molar ratio of A metal element: Sr: M metal element is 1-x-β: x: 1, 0.05≤x≤0.7, 0≤β≤0.03 , 0≤δ≤0.03. Preferably, 0.1≤x≤0.7. More preferably, 0.2≤x≤0.7. Further ...

Embodiment 1

[0107] (1) La 2 o 3 : SrCO 3 : CoO was placed in the ball mill tank of the ball mill according to the molar ratio of 0.2:0.6:1, and then ethanol was added for 2 hours of grinding. Wherein, the amount of ethanol used is 150 parts by weight relative to 100 parts by weight of solid matter. The mixture obtained by ball milling was dried in an air atmosphere at 120° C. for 5 hours, and then sieved to obtain a powder mixture with a volume average particle diameter of 0.6 μm. The powder mixture was placed in a muffle furnace, and the temperature in the muffle furnace was raised from 30°C to 950°C at a heating rate of 10°C / min, and fired in an air atmosphere for 5 hours. The roasted product is dry-ground to a volume average particle diameter of 1.5 μm, thereby obtaining the metal compound according to the present invention. After determination, the chemical composition of the metal compound is La 1-x-β Sr x CoO 3-δ , where x is 0.6, β is 0, and δ is 0.

Embodiment 2

[0113] The same method as in Example 1 is used to prepare metal compounds and polymer products and perform electroless plating. The difference is that in step (1), the roasted product is placed in an electric furnace, and argon gas is introduced into the electric furnace, and the The temperature was raised to 800 °C, at which temperature a post-treatment was carried out for 2 hours. After the post-treatment was completed, the temperature of the electric furnace was lowered to the ambient temperature (30° C.), and then the argon flow was stopped. Grinding the product obtained after the post-treatment into a volume average particle diameter of 1.5 μm, thereby obtaining the metal compound according to the present invention, after determination, the chemical composition of the metal compound is La 1-x-β Sr x CoO 3-δ , where x is 0.6, β is 0, and δ is 0.01.

[0114] After the electroless plating is completed, it is found by visual inspection that the formed metal layer is contin...
