Electrostatically Driven DPN Patterning
This family of applications describes methods for creating nanoscale patterns via the DPN process by employing surfaces and patterning compounds with opposite electrostatic charges. This method is especially useful for patterning compounds with charged polymeric backbones, including conducting polymers. Conducting polymers are at cutting edge research in photovoltaics and OLEDS.
