Abstract
Composite materials that include fluoropolymers. Methods of reducing friction, which may include contacting a first article and a second article that include or are formed of one or more fluoropolymers. The composite materials may include a fluorinated polymer and a first filler. The first filler may be present at an amount of about 3% to about 50%, by weight, based on the total weight of the first fluorinated polymer and the first filler.
Claims12
A method comprising:
- providing a first article (i) formed at least in part of a first composite material, or (ii) having a surface on which the first composite material is disposed, the first composite material comprising—
- a first fluorinated polymer;
- and
- a first filler dispersed in the fluorinated polymer;
- wherein the first filler is present at an amount of about 3% to about 50%, by weight, based on the total weight of the first fluorinated polymer and the first filler, and
- wherein the first filler comprises a first polymeric filler;
- providing a second article (i) formed at least in part of a second composite material, or (ii) having a surface on which the second composite material is disposed, the second composite material comprising—
- a second fluorinated polymer;
- and
- a second filler dispersed in the second fluorinated polymer;
- wherein the second filler is present at an amount of about 3% to about 50%, by weight, based on the total weight of the second fluorinated polymer and the second filler, and
- wherein the second filler comprises a second polymeric filler;
- contacting the first composite material and the second composite material;
- and
- applying a force to the first article, the second article, or the first article and the second article while the first composite material and the second composite material are in contact with each other, wherein the force is effective to move the first article relative to the second article.
