Poster Session May 27 and 28, 5:00-7:00pm Sheraton Boston Commonwealth Ballroom P1 Directed Assembly of Polymer Blends on Nano-Scale Patterned Self Assembled Monolayers Jason Chiota, John Shearer, Ming Wei, Carol Barry, and Joey Mead University of Massachusetts Lowell, NSF Center for High-rate Nanomanufacturing Patterned polymer structures in the area of nanotechnology offer a variety of applications which include the semiconductor industry as well as the biosensor. The majority of research in this particular area has been focused on pure block copolymers with only a few select studies dealt with polymer blends. These polymer blends studies have solely focused on uniform geometry patterns. Recently, block copolymers with the addition of a homopolymer have demonstrated the ability to phase separate into non-uniform geometries. This work investigated the assembly of polymer blends to achieve phase separation on non-uniform geometries. The two polymers chosen for this study will naturally phase separate and will utilize chemically modified surfaces to direct phase separation of the polymer blends. This work demonstrated the ability to form continuous phase separation of polymer blends on complex non-uniform geometry patterned surfaces reliably down to 100 nm. P2 High Rate Assembly and Transfer of Nanoelements Arun Kumar, Jia Shen, Ming Wei, S. Somu*, Ahmed Busnaina*, C. Barry and Joey Mead University of Massachusetts Lowell, Northeastern University*, NSF Center for High-rate Nanomanufacturing Nanoelements such as carbon nanotubes, conducting polymers and carbon black are of great interest in the researcher’s community due to their high mechanical, thermal and electrical properties. They are often combined with polymers to enhance their properties; however it is required for some of the specific applications that the particles to be in patterned form over the polymeric surface. In this work we investigate approaches to pattern the carbon nanotubes and conducting polyaniline and transfer this pattern to a polymer substrate using thermoforming, a commercially relevant process. We have used electrophoretic deposition of carbon nanotubes (Single wall (SWCNT) as well as multi wall (MWCNT)) and conducting polyaniline onto the circuits followed by transfer to a polyurethane film by thermoforming. Two circuits designs were used had a copper (Cu) wire with a width of 55 μm and the same 55 μm spacing whereas the other circuit has a gold (Au) wire with a line width of 3μm and the spacing of 9 μm. Nanoelements were deposited onto the Cu and Au wires using the electrophoresis method with direct current (DC) voltage. A novel mold design for the thermoforming process was developed, which has a removable insert to keep the patterned nanoelements circuit inside the mold. The thermoforming process parameters (temperature (heating time), forming time and vacuum) were optimized to obtain transfer of the patterned nanoelements to the polyurethane surface.
