    摘要: A conductive polymer colloidal composition that selectively forms a coating on a non-conductive surface. The conductive polymer colloidal composition is composed of a polymer and a sulfonate dopant. The conductive polymer colloidal composition may also contain conductive colloidal particles such as conductive carbon or metal salt particles, oxidants, stabilizers, and preservatives. The conductive polymer colloidal composition may be employed to selectively coat the non-conductive parts of printed wiring boards such that a uniform metal layer can be deposited on the conductive polymer coat. In addition to a uniform metal layer being formed over the conductive polymer, adhesion between the metal layer and the printed wiring board is improved.

    摘要: A method of providing an electrically conductive polymer coating on a copper clad circuit board prior to electroplating is disclosed. The method teaches the application of certain organic solvents to a conductive polymer composition already applied to the board but before drying the conductive polymer composition to remove liquids therefrom to form a conductive polymer film.

    摘要: The invention relates to a conductive dispersions used for diverse purposes such a base for electroplating nonconductors. The dispersion are characterized by use of a stabilizing quantity of a stabilizer having repeating alylkene oxide groups and a hydrophilic-lipophilic balance in excess of 12. It has been found that the stabilizers utilized in the subject compositions does result in a significant loss of conductivity in coatings formed from the dispersion.
