摘要： Disclosed herein are an aqueous dispersion including cationic polyvinyl alcohol modified polymer particles, an aqueous electrocoating material containing the dispersion and a process to produce an at least partially coated substrate using the aqueous electrocoating material. The aqueous dispersion can be prepared by reacting an intermediate including at least one polyvinyl alcohol polymer chain with a compound including at least one epoxide group and a least two blocked primary amino groups. Aqueous coating compositions including the aqueous dispersion result in improved leveling properties during film formation as well as an improved edge protection of the substrate without negatively influencing the surface roughness and adhesion as well as the deposition properties.

摘要： A method for high rate assembly of nanoelements into two-dimensional void patterns on a non-conductive substrate surface utilizes an applied electric field to stabilize against forces resulting from pulling the substrate through the surface of a nanoelement suspension. The electric field contours emanating from a conductive layer in the substrate, covered by an insulating layer, are modified by a patterned photoresist layer, resulting in an increased driving force for nanoelements to migrate from a liquid suspension to voids on a patterned substrate having a non-conductive surface. The method can be used for the production of microscale and nanoscale circuits, sensors, and other electronic devices.

摘要： Electrochemical methods for probing solid polymer electrolyte surface coatings on electrically conducting, active, three-dimensional electrode materials for use in lithium-ion batteries, to quantitatively determine the conformity, uniformity, and the presence of pinholes, and/or other defects in coatings, without requiring the detachment of the coating from the electrode or otherwise inducing damage to the coating, are described. Coated electrodes are submersed in an electrolyte solution containing a redox-active probe species which does not induce electrochemical damage to either the working electrode or the solid polymer electrolyte surface coating. For coated Cu2Sb working electrodes, molecules including a water-soluble redox active viologen moiety have been found to be effective. The current as a function of the applied potential for an uncoated working electrode is used as a baseline for testing solid polymer surface coatings on working electrodes, and the difference in the observed current between the electrodes for a given potential is a quantitative indicator of the ability of the probe species to access the surface of the working electrode through the solid polymer electrolyte coating.

摘要： A method of electrochemical deposition uses microdroplets of electrolytic solution over a targeted small circuit element. Only the targeted circuit element is electrically biased so that deposition occurs on the surface of that element, underneath the microdroplet, and nowhere else unless it is under other microdroplet(s). The invented method achieves extremely accurate and selective electrochemical deposition with a tiny amount of electrolytic solution, compared to conventional submersive and/or immersive methods, and eliminates the need for masking or etching, reducing the costs of manufacture and amount of waste electrolytic solution produced.
