Thermogravimetry, Fourier transform infrarred spectroscopy and scanning ele
ctron microscopy were performed on polyfuran films to assess thermal stabil
ity. The influence of temperature on the structure and morphology of doped
polyfuran conducting films was discussed. Thermal degradation began around
95 degrees C, although aromaticity, structure and ordered nodular morpholog
y in the growth face and the honeycomb appearance in the cross-section were
partially conserved until about 210 degrees C.
