摘要

Summary form only given. Polymers can be used as conductors ofelectricity and as “smart” materials, which change one ormore properties when activated by an electrical signal. Applicationsinclude control of electrostatic charge, batteries, fuel cells, drugdelivery devices, optical switching, optical displays, capacitors,microactuators, field-effect transistors and light emitting diodes. Theelectroactive properties of plasma polymerized aniline films have beenstudied recently by others. In our work, we have fabricated plasmapolymerized aniline resistors. To measure the resistivity of the film,gold electrodes were sputtered onto ceramic substrates. For comparisonpurposes, one electrode structure remained “blank” withoutfurther processing. Plasma polymerized aniline film with thickness 0.2μm was deposited over the remaining electrode structures. Theseresistors were annealed in a nitrogen environment at 125 C for 4 hours.While the plasma polymerized aniline film on one resistor remainedundoped the film on another was doped by immersion in a 1 molar HClsolution for 7 hours. Doping was followed by vacuum drying. Resistorvalues for the blank electrode structure, tor the resistor with undopedfilm and for the resistor with doped film were measured from the slopeof volt-ampere characteristics recorded with a Keithley 617Electrometer. The undoped film had a conductivity less than 4×10-2 s/cm while the film doped with the liquid HCl treatmenthad a conductivity of 4×10-10 to s/cm, a result that isconsistent with earlier work by Gong et al. (1998)
