Carbon nanotubes–SU8 composite for flexible conductive inkjet printable applications.
The groups of Prof. László Forró (Laboratory of Nanostructures and Novel Electronic Materials) and Prof. Jürgen Brugger (Microsystems Laboratory 1) have developed a conducting composite based on multi-walled carbon nanotubes and bisphenol A novolak epoxy resin (SU8) for inkjet printing purposes. They could deposit regular conducting stripes and arrays of 150 μm spots on glass and on flexible polyethylene terephthalate (PET) films. The UV and temperature processed structures showed very good adhesion and reasonably good resistivity with a low concentration of carbon nanotubes. Their composite material for inkjet deposition is completely compatible with current MEMS fabrication processes.
