Patent number: 11912900Abstract: Carbon nanotube (CNT) agglomerates can be aligned along the field lines between adjacent electrodes to form conductive bridges. The present invention is directed to a stepwise process of dielectrophoretic deposition of CNTs to form conducting bridges between adjacent electrodes spanning lengths over 50 microns. The CNT bridges are permanently secured using electrodeposition of the conducting polymer polypyrrole. Morphologies of the CNT bridges formed within a frequency range of 1 kHz and 10 MHz are employed and explained as a consequence of interplay between dielectrophoretic and electroosmotic forces. Postdeposition heat treatment increases conductivity of CNT bridges likely due to solvent evaporation and resulting surface tension inducing better contact between CNTs.Type: GrantFiled: April 6, 2021Date of Patent: February 27, 2024Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Lawrence Kulinsky, Tuo Zhou

Patent number: 11840769Abstract: The present invention is directed to devices and methods for assembling particulates through the use of non-contact electrokinetic forces applied to polymeric, organic, non-organic, and metallic micro- and nano-particulates in an aqueous solution. The present invention features an electrode comprising a conductive substrate with a layer of photosensitive polymer disposed on it with a plurality of windows etched into the layer. The plurality of windows expose certain portions of the conductive substrate. Applying electric signals to the conductive substrate (e.g. by a function generator) causes materials to attract to only the exposed portions of the conductive substrate. The materials may comprise a plurality of organic, non-organic, and metallic micro- and nano-particulates disposed in an aqueous solution.Type: GrantFiled: May 7, 2021Date of Patent: December 12, 2023Assignee: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Lawrence Kulinsky, Tuo Zhou
