Method for Manufacturing Highly Conductive Carbon Fiber Using a Cobalt-Based Reducing Agent

Method for Manufacturing Highly Conductive Carbon Fiber with Reduced Phosphorus Content Using a Cobalt-Based Reducing Agent

This technology relates to a method for manufacturing highly conductive carbon fiber. More specifically, it involves enhancing conductivity through electroless nickel plating, while utilizing a cobalt-based reducing agent to minimize phosphorus content in the nickel layer, resulting in carbon fiber with superior conductivity. The highly conductive carbon fiber produced by this invention exhibits excellent heat resistance, chemical stability, electrical conductivity, electromagnetic shielding, and flexibility, making it suitable for use as an internal filler for high-conductivity plastics.

Existing solutions in this field have faced structural and functional limitations that required improvement.

This technology provides a method for manufacturing highly conductive carbon fiber using a cobalt-based reducing agent, which can be applied across relevant industries to enhance performance and efficiency.
