Electroless Nickel Deposition: An Alternative for Graphene

Electroless plating is an autonomous, self-catalytic process based on the reduction of metallic ions from an aqueous metal salt-based solution using, for example, a hypophosphite: In electroless nickel plating, once the nickel deposition is initiated, each deposited metal layer acts as a catalytic base, enabling further growth for thicker and more coherent coatings compared to its

US Patent Application for ELECTROLESS PLATING OF

Silver-plated glass or any other silver-plated filler with an insulator core suffer low conductive performance, and are poor substitutes for silver or silver-plated copper. Silver-coated graphite is lower in cost than, and can deliver comparable initial conductivity to, bulk silver or silver-plated copper, without the oxidative stability problems associated with copper.

inorganic chemistry

I'm researching how the classic "alchemy" demonstration works in which zinc is plated onto a copper penny in a solution of sodium hydroxide. Most online resources refer to the electroplating of copper with zinc, which is not what I'm interested in. The best article I've been able to find on the electroless plating of zinc onto copper is from the Royal Chemistry Society.

Aging Effect on Adhesion Strength between Electroless

The effect of atmospheric aging on the adhesion strength between electroless copper and polyimide films was investigated. 100 nm thick electroless copper was plated on polyimide film and 10 m of copper electroplating was performed successively. Aging was

Nickel or copper coated graphite powder

Nickel or copper coated graphite powder 1999 I am a student in graduate school. I study modeling of melted Al. I need Ni-coated graphite powder or Cu-coated graphite powder. The size of powder is 10-200 micrometer, but size must be constant. If you have

Electroless nickel–phosphorus plating on graphite powder

2007/12/15Electroless deposition technique was used to coat Ni–P on graphite particles with high deposition rate and bath stability by activating the graphite powder in a furnace at 380 C for 1 h. The effect of plating time, size of the powder and weight of the powder were studied.

Conductive Coating on Plastic and Plating on Plastic

Electroless Plated Parts Electroless Plating with copper, nickel or nickel plating over copper are cost effective methods that address a wide range of engineering requirements for plastic components. Read more Conductive Painted Parts A full range of

Electroless Copper Plating Technology for Graphite

Electroless copper plating was Used for graphite powder to solve the interface problem in metal7 graphite composite material manufacture and improve its comprehensive properties. But it was difficult to acquire graphite powder coated with copper because graphite powder was minuteness, hydrophobic and surface inert material.
