Nanotechnology - Control over polymers at the nanometer level

The overall research interest of my group is the use of polymers as building blocks in nanotechnology. State-of-the-art lithographic techniques like focused ion beam, e-beam or extreme UV lithography are able to generate patterns in the sub-100 nm region. However, these techniques have their limitations in terms of materials that can be patterned and the high costs of investment in equipment. Alternative techniques based on self-assembly and self-organization of organic and inorganic particles into well-defined regular nanostructures are therefore highly desirable. Polymers could be ideal building blocks for such approaches because of their natural 5-100 nm lengthscale, ease of synthesis, and rich chemistry. Currently, it is impossible to design and fabricate arbitrary polymers with well-defined shape and functionality. If we are to bridge the gap between the biological world and nanofabrication, major advances in the control over polymeric materials at the nanometer level are necessary. As a result of recent progress in controlling lengthscales of polymer materials at the nanometer level, we are starting to explore the effects of nanoconfinement on phase-separation, glass transition temperature, conductivity, and optical properties, in a variety of polymer systems.

 

The tools we are developing:

Nanocontact printing
Micro and nanoembossing
Controlled phase separation of block copolymers

 

Fields of potential applications:

Polymer electronics
Nanoscale eletronic and biological devices
Optoelectronic devices
Growth of polymer brushes
