Surface Grafting of Polypyrrole onto Silicon Wafers



Daeson Sohn, Hyoseung Moon, Michael J. Fasolka, Naomi Eidelman, Sang-Mo Koo, Curt A. Richter, Eun S. Park, Joseph Kopanski, Eric J. Amis


A micromolding technique in capillaries was adapted to make uniform patterns of polypyrrole (Ppy), and the conductivities of the patterns were measured by direct contact IV curves and conductance AFM methods. Noncovalently bound Ppy patterns have high conductivity (low resistivity) before doping and brittle characteristics. However, the covalently grafted Ppy pattern shows relatively low conductivity and sticky viscoelastic properties.
