Abstract:
There is provided a process for forming a layer of electroactive material having a substantially flat profile. The process includes the steps of providing a workpiece having at least one active area; depositing a liquid composition including the electroactive material onto the workpiece in the active area, to form a wet layer; treating the wet layer on the workpiece at a controlled temperature in the range of -25 to 80°C and under a vacuum in the range of 10 -6 to 1,000 Torr, for a first period of 1-100 minutes, to form a partially dried layer; and heating the partially dried layer to a temperature above 100°C for a second period of 1-50 minutes to form a dried layer.
Abstract:
There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer having a first surface energy; treating the first layer with a priming material to form a priming layer; exposing the priming layer patternwise with radiation resulting in exposed areas and unexposed areas; developing the priming layer to effectively remove the priming layer from the unexposed areas resulting in a first layer having a pattern of developed priming layer, wherein the pattern of developed priming layer has a second surface energy that is higher than the first surface energy; and forming the second layer by liquid depositions on the pattern of developed priming layer on the first layer. The priming material has at least one unit of Formula I In Formula I: R1 through R6 are D, alkyl, aryl, or silyl, where adjacent R groups can join together to form an aromatic ring; X is a single bond, H, D, or a leaving group;Y is H, D, alkyl, aryl, silyl, or vinyl; a-f are an integer from 0-4; m, p and q are an integer of 0 or greater.

Abstract:
A rotational actuator/motor based on rotation of a carbon nanotube is disclosed. The carbon nanotube is provided with a rotor plate attached to an outer wall, which moves relative to an inner wall of the nanotube. After deposit of a nanotube on a silicon chip substrate, the entire structure may be fabricated by lithography using selected techniques adapted from silicon manufacturing technology. The structures to be fabricated may comprise a multiwall carbon nanotube (MWNT), two in plane stators (26, 28) and a gate stator (30) buried beneath the substrate surface. The MWNT is suspended between two anchor pads and comprises a rotator attached to an outer wall and arranged to move in response to electromagnetic inputs. The substrate is etched away to allow the rotor to freely rotate. Rotation may be either in a reciprocal or fully rotatable manner.
