Abstract

Metalized plastic substrates, and methods thereof are provided herein. The method includes providing a plastic having a plurality of accelerators dispersed in the plastic. The accelerators have a formula ABO3, wherein A is one or more elements selected from Groups 9, 10, and 11 of the Periodic Table of Elements, B is one or more elements selected from Groups 4B and 5B of the Periodic Table of Elements, and O is oxygen. The method includes the step of irradiating a surface of plastic substrate to expose at least a first accelerator. The method further includes plating the irradiated surface of the plastic substrate to form at least a first metal layer on the at least first accelerator, and then plating the first metal layer to form at least a second metal layer.

First claim

What is claimed is:

1. A plastic article comprising: a plastic substrate having a plastic, at least one accelerator, and at least a first and a second metal layers plated on the at least one accelerator, the accelerator having a formula ABO 3 , wherein A is one or more elements selected from Groups 9, and 10 of the Periodic Table of Elements, B includes one or more elements selected from Groups 4B and 5B of the Periodic Table of Elements, and O is oxygen.

2. The plastic article of claim 1 , wherein the metal layers are selected from the group consisting of: Ni—Cu—Ni, or Ni—Cu—Ni—Au, or Cu—Ni, or Cu—Ni—Au.

3. The plastic article of claim 2 , wherein the nickel layers each have a thickness ranging from about 0.1 microns to about 50 microns; the copper layers each have a thickness ranging from about 0.1 microns to about 100 microns; and the aurum layers each have a thickness ranging from about 0.01 microns to about 10 microns.

4. The plastic article of claim 1 , wherein the accelerator has an average diameter ranging from about 20 nanometers to about 100 microns.

5. The plastic article of claim 1 , wherein the amount of the accelerator ranges from about 1 wt % to about 40 wt % of the plastic substrate.

6. The plastic article of claim 1 , wherein the plastic substrate further comprises at least one additive selected from the group consisting of: an antioxidant, a light stabilizer, a lubricant, and inorganic fillers.

7. The plastic article of claim 1 , wherein A further includes one or more elements selected from Groups 1 and 2 of the Periodic Table of Elements and the lanthanide series of the Periodic Table of Elements.

8. A plastic article comprising: a plastic substrate having a plastic, at least one accelerator, and at least a first and a second metal layers plated on the at least one accelerator, the accelerator having a formula ABO 3 , wherein A includes one or more elements selected from Groups 9, 10, and 11 of the Periodic Table of Elements, B includes one or more elements selected from Groups 4B and 5B of the Periodic Table of Elements, and O is oxygen; and
wherein when A is Cu, the accelerator is selected from the group consisting of:
Na 0.04 Ca 0.98 Cu 3 Ti 4 O 12 , La 0.01 Ca 0.99 Cu 3 Ti 4 O 12 , CuTiO 3 , CuNiTi 2 O 6 , CuNbO 3 , CuTaO 3 and CuZrO 3 .
