Abstract
A improved process for preparing a conductive polymer dispersion is provided as is an improved method for making capacitors using the conductive polymer. The process includes providing a monomer solution and shearing the monomer solution with a rotor-stator mixing system comprising a perforated stator screen having perforations thereby forming droplets of said monomer. The droplets of monomer are then polymerized during shearing to form the conductive polymer dispersion.
Claims9
A process for preparing a conductive polymer dispersion comprising:
- providing a monomer;
- mechanically mixing said monomer to form droplets comprising said monomer;
- and
- polymerizing said monomer in said droplet with an oxidizer thereby forming particles of intrinsically conductive polymer with a particle size of no more than 200 nm.
