Abstract:
A method is provided for pretreating metallic fillers adapted to be added into an organic polymer resin matrix adapted to cure into a material, wherein pretreating the fillers enhances the mechanical and electrical properties of the cured material. The method includes selecting an organofunctional silane based on compatibility of a functional organic with a selected polymer; determining an amount of silane required for treatment of the fillers by calculating the amount of silane required to provide monomolecular coverage of the particle surfaces of the filler based on a specific surface area measurement of the particle surfaces; uniformly dispersing the required amount of silane over the filler; allowing adequate time for the silane to react with particle surfaces of the filler; and mixing the treated filler into the polymer resin.
