| Description of Research | |||
| Recent technological fields such as telecommunications and microelectronics present new challenges to examine the potential of polymers tailored to the specific needs of these industries. Dr. Hammond approaches this challenge with a two-component research program based on polymer design and synthesis, and basic polymer device fabrication. The first component focuses on the synthesis of liquid crystalline block copolymers with unique electro- and mechano-optical properties. Her goal is to exploit the well defined phase morphologies of highly segregated block copolymers to produce liquid crystalline/amorphous block copolymers ideal for optical device applications. Highly organized block copolymer films and fibers are expected to result in materials with highly anisotropic mechanical and electro-optical properties which could form the basis of self-formed active waveguide devices and electrically or mechanically induced smart materials. The second component involves the patterned deposition or synthesis of polymers onto surfaces to form thin film devices. Self-assembled monolayers are patterned onto gold or glass substrates, and used as molecular templates for ionic multilayer assembly of polyions. Using this technique, nanometer thick polymer layers are patterned onto a surface to form micron-sized features; these patterned thin films show potential in the fields of integrated optics, sensors, and other microfabrication applications. |
