AbstractWe present a methodology based on Dip-Pen Nanolithography 1 to fabricate nanoscale surface patterns composed of polyelectrolytes. Two widely used polymers Poly(diallyldimethylammonium chloride) (PDDA) and Poly(sodium 4-styrenesulfonate) PSS were chosen as the DPN “inks”. Patterns were created and evaluated on silicon oxide surfaces using an Atomic Force Microscope (AFM). To compare the polymer packing and the height of the nanopatterns, additional fabrication was performed using microcontact printing. We were able to generate structures with better polymer packing using DPN and control the height of the polymer structures more reproducibly compared to microcontact printing.

Polymer nanostructures were directly written onto substrates in ultra-high vacuum. The polymer ink was coated onto atomic force microscope (AFM) probes that could be heated to control the ink viscosity. Then, the ink-coated probes were placed into an ultra-high vacuum (UHV) AFM and used to write polymer nanostructures on surfaces, including surfaces cleaned in UHV. Controlling the writing speed of the tip enabled the control over the number of monolayers of the polymer ink deposited on the surface from a single to tens of monolayers, with higher writing speeds generating thinner polymer nanostructures. Deposition onto silicon oxide-terminated substrates led to polymer chains standing upright on the surface, whereas deposition onto vacuum reconstructed silicon yielded polymer chains aligned along the surface.

AMF anodization lithography was performed on organic thin films with conducting polymers which is poly(3,4-ethylenedioxythiophene). The conductivity of PEDOT thin films was changed by different dopants and organic solvents. Two different dopants are poly(4-styrenesulfonate) and di(2-ethylhexyl)-sulfosuccinate. Also, DMF and IPA were used to prepare the PEDOT thin films doped with PSS and DEHS on silicon surface. The conductivities of these PEDOT variants were compared by obtaining their I–V curves between tip and thin films using AFM. Silicon oxide nanopatterns with higher aspect ratios can be obtained from the films with higher conductivity.
