Mark Martello has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • CONDUCTIVE POLYMER COMPOSITIONS
    Publication number: 20080017834
    Abstract: Electrically conductive polymer compositions are provided. The compositions are dispersed in an aqueous liquid medium having an oxygen content less than 10% of the saturated level. The compositions can be an electrically conductive polymer doped with a fluorinated acid polymer, an electrically conductive polymer in admixture with a fluorinated acid polymer, or mixtures thereof. The conductive polymer composition has a conductivity that changes by less than 10% in 30 days.
    Type: Application

  • Buffer compositions
    Publication number: 20060289843
    Abstract: Buffer compositions comprising semiconductive oxide particles and at least one of (a) a fluorinated acid polymer and (b) a semiconductive polymer doped with a fluorinated acid polymer are provided. Semiconductive oxide particles include metal oxides and bimetallic oxides. Acid polymers are derived from monomers or comonomers of polyolefins, polyacrylates, polymethacrylates, polyimides, polyamides, polyaramids, polyacrylamides, polystyrenes. The polymer backbone, side chains, pendant groups or combinations thereof may be fluorinated or highly fluorinated. Semiconductive polymers include polymers or copolymers derived from thiophenes, pyrroles, anilines, and polycyclic heteroaromatics. Methods for preparing buffer compositions are also provided.
