Abstract: An electrodeposition coating method includes a degreasing/cleaning step, a chemical conversion step, and an electrodeposition coating layer formation step. The degreasing/cleaning step includes a degreasing step of ultrasonically vibrating a degreasing solution in which a target object is immersed, using an ultrasonic vibrator. The electrodeposition coating layer formation step includes: a first electrodeposition step; a first rinsing step; a rinse water removal/reduction step of removing or reducing rinse water on a rinse water stagnating surface of the target object; a thermal flow step of allowing the first electrodeposition coating film to thermally flow so that the first electrodeposition coating film formed on a portion of the target object near a first counter electrode has a higher electrical resistance than the first electrodeposition coating film formed on a portion of the target object far from the first counter electrode; and a second electrodeposition step.

Abstract: The present disclosure discloses a continuous electrophoretic deposition modified carbon fiber reinforced multi-matrix composite and a preparation method thereof, composing of a carbon fiber with a volume fraction of 30-55%, an inorganic powder with a volume fraction of 3-25% and a matrix with a volume fraction of 20-67%, wherein the inorganic powder is wrapped on the surface of the carbon fiber filament or embedded in the carbon fiber bundle, and the concentration gradually decreases from the fiber filament to the surface of the fiber bundle. The preparation method of the composite is as follows: (1) pretreating the carbon fibers; (2) preparing a slurry of the inorganic powder; (3) widening the pretreated carbon fiber to form a carbon fiber strip, and then carrying out electrophoretic deposition on the inorganic powders; (4) preparing a preform from the deposited carbon fibers; and (5) compounding a matrix in the preform.

Abstract: Described herein are methods for the surface deposition of polyionic species on a substrate surface. This deposition process can be triggered facilely by oxidizing organometallic species present on the surface of the substrate. This approach is quite general, affording quantitative deposition of polyionic species with a wide range of chemical identities (e.g., synthetic polymers, peptides and DNA) and molecular weights. This approach is in addition suitable for surface deposition of several types of functional materials, including proteins (antibodies), nanomaterials, colloids, lipid vesicles, among others.

Abstract: An electrochemical probe comprises a wire bundle including two or more wire electrodes made of conducting material arranged alongside each other, and insulating material surrounding the electrodes. An impedance reducing layer of metal or metal oxide nano-structures is deposited on tips of the wire electrodes at a first end of the bundle. A functionalization layer is deposited on the impedance reducing layer at the first end of the bundle. Such a probe is particularly useful for electrochemical sensing applications such as neuronal scanning.
