  • Patent number: 10023735
    Abstract: This application describes methods of forming an object. The methods described include forming a mixture with i) one or more primary diamines, ii) one or more polymerizable monomers, iii) a formaldehyde-type reagent, and iv) a polymerization initiator; forming a gel by heating the mixture to a temperature of at least 50° C.; and curing the one or more polymerizable monomers by activating the polymerization initiator. The one or more primary diamines may include one or more amine functional oligomers and/or primary aromatic diamine small molecules. The one or more polymerizable monomers may include styrenics, acrylates, methacrylates, vinyl esters, unsaturated polyesters, and derivatives thereof. The gel is a polyhemiaminal (PHA), a polyhexahydrotriazine (PHT), and/or a polyoctatriazacane (POTA) polymer, and curing of the gel forms an interpenetrating network of the PHA/PHT/POTA and the polymer formed from the polymerizable monomers.

  • Publication number: 20100279095
    Abstract: A process for forming a composite film on a substrate comprises providing a suspension comprising an ionised polymer and functionalised carbon nanotubes in a solvent, at least partially immersing the substrate and a counterelectrode in the suspension, and applying a voltage between the substrate and the counterelectrode so as to form the composite film on the substrate. Electrical charges on the polymer and on the nanotubes have the same sign and the voltage is applied such that the charge on the substrate has the opposite sign to the charge on the polymer and the nanotubes.

  • Publication number: 20080232038
    Abstract: The invention discloses a method for forming a conductive polymer with an electrophoretic deposition cell, into porous anode for electrolytic capacitors. The conductive polymer is directly deposited on the oxide layer of the anode body. The electrolytic polymerized conductive polymer material form the cathode in solid electrolyte capacitors. The method allows low ESR capacitors to be produced. The invention provides a high yield and low cost industrial process with efficient materials utilization. The present invention successfully deposits particles from dispersion on continuous, highly insulating dielectric layers using electrophoretic deposition by use of EPD voltage near or above the anode dielectric formation voltage, where the anode body is positively biased relative to the EPD counter electrode, thereby allowing a current to be driven through the dielectric layer.
