Abstract

A method is described for the production of a manufactured article (20) constituted of an elastomeric polymer substrate, in selected zones of which there are deposits of particles of nanometric size of a metal or some other compound which create a region (24) of the polymeric element having desired electrical, biocompatibility and/or dielectric properties, and such that said properties are maintained even after numerous elastic deformations of the manufactured article; the invention also relates to functionalized elastomeric manufactured articles obtained by means of said method.

Claims8

Dependent claims

A biocompatible elastomeric device, said device comprising:

an elastomeric support, said elastomeric support having a surface layer portion and a lower portion, and
one or more functionalized and geometrically defined nanocomposite regions within the surface layer portion of the elastomeric support, said one or more nanocomposite regions comprising neutral nanoclusters of metal, metal oxide, or other metal compound, said neutral nanoclusters having a dimension of between 1 nm to 10 nm and a density within the surface layer portion of greater than about 5×10−3 nanoclusters/nm3,
wherein one or more neutral nanoclusters of the neutral nanoclusters are implanted in the surface layer portion of the elastomeric support, and
wherein the one or more neutral nanoclusters that are implanted are not exposed outside of the surface layer portion.
