Abstract
Through assessment of the steady-state electrical resistance changes of poly(3,3"-didecyl-2,2":5',2"-terthiophene) doped with various counter ions upon exposure to multiple concentrations of 27 volatile organic chemicals, it has been shown that a linear relationship exists between log(1/C-v) and T-b (C,, being the analyte concentration required to generate a fixed sensor response, and Tb being analyte boiling point) for analytes which share a common functional group. The study supports a physico-chemical model of conducting organic polymer gas sensor responses based on non-specific partition of the analyte between vapour and polymer phases.
