Method and apparatus related to nanoparticle systems

摘要

This publication discloses a method and apparatus for functionalizing nanoparticle systems. The method comprises treating a nanoparticle-containing layer so as to produce a pattern of structurally transformed zones, the treatment comprising applying an electric field through the nanoparticle layer. According to the invention an AC-field capacitively coupled to the nanoparticle-containing layer is used as said electric field. The treatment preferably results in at least partly sintered structures, which can be used as conductors, for example. The document discloses several realizations for utilization of the disclosed functionalization in mass-fabrication lines.

1. A method for functionalization of nanoparticle systems, comprising treating a nanoparticle-containing layer so as to produce a pattern of structurally transformed zones, the treatment comprising applying an electric AC-field through the nanoparticle-containing layer to capacitively couple with the nanoparticle-containing layer in a non-contact process to effect selective functionalization of said nanoparticle-containing layer by structurally transforming nanoparticles according to said pattern, said method using an electric field strong enough to sinter or fully coalesce said nanoparticles.
