Abstract
A method relating to making a metal coated filler includes mixing a solution of an organic diol with a plurality of porous filler particles to obtain a support mixture; contacting a metal salt solution with the support mixture forming a reaction mixture; and heating the reaction mixture to a temperature within a temperature range from about 50 degrees Celsius to about 200 degrees Celsius. The metal cations in the metal salt solution are reduced to metal particles by the organic diol and are disposed on the porous filler particles and on filler particle pore surfaces. The metal coated filler may then be optionally isolated. Electrically and/or thermally conductive articles including the metal coated fillers and methods for their manufacture are also disclosed.
