摘要:
Disclosed herein are methods and apparatuses for curing a polymerizable material capable of cure through a redox reaction by electrically contacting the polymerizable material with an anode and a cathode to create a voltage bias that promotes curing of the polymerizable material.
摘要:
A film of a composite material is deposited by electropolymerization onto electrically conductive surface. A mixture comprising a monomer, a substance forming a dopant, a supporting electrolyte and a solvent is subjected to electrolysis in which the conductive surface to be coated is used as either cathode or anode. The cathode or anode is polarized to a potential between the electron transfer between the electrically conductive surface and the monomer. Prior to electrolysis, a solution is made from the mixture containing the substance forming a dopant either as anion, cation, molecule, and/or as undissociated complex.
摘要:
In accordance with the present invention, electropolymerization in a substantially aqueous solution is used to form thick (e.g. greater than 2 microns or 30 weight %) and thermally stable coatings of thermoplastic materials onto electrically conductive filler materials (e.g. rods, plates, fibers). In a first preferred embodiment, the thick thermoplastic matrix comprises a copolymer of 3-carboxyphenyl meleimde and styrene. In a second preferred embodiment, cyclic (and preferably aromatic) N-substituted methacrylamide monomers are electropolymerized onto electrically conductive (e.g., graphite) filler (e.g., fibers, plates, film or cloth) to form a novel polymer composite exhibiting high Tg as well as a controlled degree of cross-linking which can prevent flow at high temperature. This invention is particularly will suited for direct preparation of thermoplastic prepregs containing commercially available bundles of graphite fibers. These prepregs are then molded under heat and pressure so as to form a thermoplastic matrix composite with good fiber distribution, uniformity and high temperature resistance.

摘要:
Polymerization of an ethylenically unsaturated compound is achieved by means of free radical initiators derived from the reaction of an aldehyde/bisulfite adduct with cupric ions resulting from electrolysis involving a copper anode. By including a photoconductive cathode in the system image-wise light exposure effects the formation of polymeric images in the polymerizable composition.

Polymerization of monofunctional monomers and multifunctional monomers and polymers is initiated by application of electrical field. No solutions containing electrolytes are required. Imagewise field application provides raised polymeric images which may be used for printing plates or lithographic masters.
