POLYANILINE THIN-FILMS FOR GAS-SENSING (1995)
Journal Article
Agbor, N., Petty, M., & Monkman, A. (1995). POLYANILINE THIN-FILMS FOR GAS-SENSING. Sensors and Actuators B: Chemical, 28(3), 173-179

Thin films of polyaniline have been deposited by spinning, evaporation and by the Langmuir-Blodgett technique. The films are shown to possess slightly different in-plane electrical conductivities, reflecting differences in their chemical structure an... Read More about POLYANILINE THIN-FILMS FOR GAS-SENSING.

THERMOELECTRIC-POWER MEASUREMENTS IN HIGHLY CONDUCTIVE STRETCH-ORIENTED POLYANILINE FILMS (1995)
Journal Article
Holland, E., & Monkman, A. (1995). THERMOELECTRIC-POWER MEASUREMENTS IN HIGHLY CONDUCTIVE STRETCH-ORIENTED POLYANILINE FILMS. Synthetic Metals, 74(1), 75-79

We have measured the thermopower of stretch-oriented, free-standing films of polyaniline (PANi) which after protonation have electrical conductivities of the order 300 S cm(-1) at room temperature. Our data show a striking contrast between trends in... Read More about THERMOELECTRIC-POWER MEASUREMENTS IN HIGHLY CONDUCTIVE STRETCH-ORIENTED POLYANILINE FILMS.

GAS-SENSING USING A CHARGE-FLOW TRANSISTOR (1995)
Journal Article

We report on the successful fabrication of an array of charge-flow transistors incorporating polyaniline films. The electrical d.c. characteristics have been found to be similar to those of conventional metal-oxide-semiconductor field-effect transist...

ANISOTROPY OF THE CONDUCTIVITY IN POLYANILINE FILMS - EFFECT OF CHAIN ORIENTATION AND HYDRATION (1995)
Journal Article
Travers, J., Leguyadec, P., Adams, P., Laughlin, P., & Monkman, A. (1995). ANISOTROPY OF THE CONDUCTIVITY IN POLYANILINE FILMS - EFFECT OF CHAIN ORIENTATION AND HYDRATION. Journal de chimie physique, 92(4), 1009-1012

Proton relaxation times T-1 and DC conductivity have been measured on unstretched and stretched polyaniline films, in the dried and the hydrated states. It is shown that polaron motion is highly anisotropic at the chain scale and that stretching incr...

POLYANILINE, AIR-STABLE ORGANIC METAL - FACT, NO LONGER FICTION (1995)
Journal Article
Monkman, A., Adams, P., Laughlin, P., & Holland, E. (1995). POLYANILINE, AIR-STABLE ORGANIC METAL - FACT, NO LONGER FICTION. Synthetic Metals, 69(1-3), 183-186

Via improved chemistry we have increased the maximum attainable conductivity in oriented polyaniline. D.C. conductivity's approaching 10(4) Scm(-1) have been measured. Temperature dependent transport measurements reveal that our new polyaniline behav... Read More about POLYANILINE, AIR-STABLE ORGANIC METAL - FACT, NO LONGER FICTION.

MU-SR STUDIES OF SPIN EXCITATIONS IN POLYANILINE (1995)
Journal Article

Muon techniques have been used to study the spill excitations in polyaniline. The relaxation rate provides information about the spin dynamics. 1D spin diffusion is observed at low temperature in non-metallic materials with a crossover to 2 or 3D beh...
