Solution Overview
Problem
Existing methods for metalizing plastic substrates are complex, energy-intensive, and often result in low adhesive force between the metal layer and the plastic support, limiting their efficiency and cost-effectiveness.
Innovation Solution
A method involving the dispersion of CuWO4 or CuSeO4 accelerators within the plastic substrate, followed by selective laser irradiation to expose these accelerators, allowing for direct chemical or electroplating to form a strong metalized layer with enhanced adhesive properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional metalization methods using metal core formation and chemical plating are used, then metalized layers can be formed on plastic substrates, but the process becomes complex and energy consumption increases
Solution Approach 1:
The patent incorporates metal-containing compounds (such as copper chromite, nickel chromite, or cobalt chromite) directly into the plastic substrate during manufacturing. This preliminary incorporation eliminates the need for subsequent metal core formation steps, simplifying the overall process while ensuring reliable metalized layer formation through direct electroless plating onto the embedded metal compounds.
Solution Approach 2:
The patent removes the complex multi-step metal core formation process from the conventional metalization method. By directly embedding metal-containing compounds into the plastic substrate, the method extracts and eliminates the intermediate catalytic layer formation steps, resulting in a simpler and more energy-efficient process.
2Reliability
If conventional metalization methods are used, then metalized layers can be formed on plastic substrates, but adhesive force between the coating and plastic support remains low
Solution Approach 1:
The patent creates a composite structure by embedding metal-containing compounds (such as copper chromite, nickel chromite, or cobalt chromite) directly into the plastic substrate matrix. This composite approach ensures strong interfacial bonding between the metal compounds and the plastic, providing excellent adhesive force for the subsequent metalized layer while maintaining the structural integrity of the substrate.
3Use of energy by stationary object
If selective laser irradiation is used to activate accelerators, then direct chemical plating can be performed with lower energy consumption, but the accelerators must be properly dispersed in the plastic
Solution Approach 1:
The patent incorporates metal-containing compounds directly into the plastic substrate during the initial manufacturing process, ensuring uniform dispersion throughout the material. This preliminary and thorough mixing eliminates aggregation issues and ensures that when laser irradiation is applied, the accelerators are evenly distributed and readily available for activation, enabling direct chemical plating with lower energy consumption.
