  • Method for surface imprinted films with carbon nanotubes
    Patent number: 7435310
    Abstract: A method of making films surface imprinted with nanometer-sized particles to produce micro- and/or nano-structured electron and hole collecting interfaces, include providing at least one transparent substrate, providing at least one photoabsorbing conjugated polymer, providing a sufficient amount of nanometer-sized particles to produce a charge separation interface, providing at least one transparent polymerizable layer, embedding the nanometer-sized particles in the conjugated polymer, applying the polymerizable layer and the conjugated polymer/nanometer-sized particle mixture on separate substrates where the nanometer-sized particles form a stamp surface, imprinting the stamp surface into the surface of the polymerizable film layer to produce micro- and/or nano-structured electron and hole collecting interfaces, polymerizing the polymerizable film layer to form a conformal gap, and filling the gap with at least one photoabsorbing material to promote the generation of photoexcited electrons and transport to
    Type: Grant

  • Surface imprinted films with carbon nanotubes
    Patent number: 7119028
    Abstract: A film surface imprinted with nanometer-sized particles to produce micro- and/or nano-structured electron and hole collecting interfaces, including: at least one substrate; at least one photoabsorbing conjugated polymer (including polybutylthiophene (pbT)) applied on a substrate, nanometer-sized particles including multiwalled carbon nanotubes (MWNT) to produce a charge separation interface; at least one transparent polymerizable layer, wherein the MWNT are embedded in the conjugated polymer to produce mixture and applied on a substrate to form a MWNT bearing surface film layer to form a stamp surface which is imprinted into the surface of the polymerizable film layer to produce micro- and/or nano-structured electron and hole collecting interfaces; polymerizing the polymerizable film layer to form a conformal gap between the MWNT stamp surface and the surface of the polymerizable film layer, and filling the gap with a photoabsorbing material to promote the generation of photoexcited electrons and transport to
