Abstract

A composition of matter includes a particle, a resin bonding functionality bonded to a first portion of the particle, and a lubricating functionality bonded to a second portion of the particle.

First claim

The invention claimed is:

1. A process of forming a multiple-function filler material for a polymeric application, the process comprising:
bonding a first set of functional groups to a first portion of a particle;
bonding a second set of functional groups to a second portion of the particle to form a multiple-function filler material; and
removing the particle from an encapsulant after bonding the first set of functional groups to the first portion of the particle to expose the second portion of the particle for bonding the second set of functional groups to the second portion of the particle.

2. The process of claim 1 , wherein the first set of functional groups includes resin bonding functional groups, and wherein the second set of functional groups includes lubricating functional groups.

3. The process of claim 2 , wherein the particle includes a silica particle.

4. The process of claim 3 , wherein the resin bonding functional groups are bonded to the silica particle using a vinyl chloride solution.

5. The process of claim 3 , wherein the lubricating functional groups are bonded to the silica particle using a silane material that includes multiple fluorine groups.

6. The process of claim 5 , wherein the silane material includes trichloro(3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl)silane.

7. The process of claim 1 , wherein the first set of functional groups includes lubricating functional groups, and wherein the second set of functional groups includes resin bonding functional groups.
