Abstract:
A fabricated substrate has at least one plurality of posts. The plurality is fabricated such that the two posts are located at a predetermined distance from one another. The substrate is exposed to a fluid matrix containing functionalized carbon nanotubes. The functionalized carbon nanotubes preferentially adhere to the plurality of posts rather than the remainder of the substrate. A connection between posts of the at least one plurality of posts is induced by adhering one end of the functionalized nanotube to one post and a second end of the functionalized carbon nanotube to a second post.

Abstract:
Methods involve a combination of polyelectrolyte multilayer (PEM) coating or silane self assembly on a substrate; microcontact printing; and conductive graphite particles, especially size controlled highly conductive exfoliated graphite nanoplatelets. The conductive graphite particles are coated with a charged polymer such as sulfonated polystyrene. The graphite particles are patterned using microcontact printing and intact pattern transfer on a substrate that has an oppositely-charged surface. The method allows for conductive organic patterning on both flat and curved surfaces and can be used in microelectronic device fabrication.

Abstract:
A method for making a touch panel is provided. A number of first transparent conductive layers are formed on an insulative substrate. Each of the first transparent conductive layers is resistance anisotropy. A number of first electrodes and a first conductive trace are formed corresponding to each first transparent conductive layer. An adhesive layer is formed on the insulative substrate to cover the first transparent conductive layers. A carbon nanotube layer is formed on the adhesive layer. The carbon nanotube layer is patterned to obtain a number of second transparent conductive layers spaced from each other and with each corresponding to one first transparent conductive layer. A number of second electrode and a second conductive trace are formed corresponding to each second transparent conductive layer.
