This paper describes the effect of hypermer PS3 surfactant on the response of PEA \ CB sensors to 20000 ppm of propanol. The surfactant was varied from 10-50 mg and its effect on the response and properties of the sensor material were examined. It was found that increasing the amount of surfactant in the sensors significantly improved batch-to-batch reproducibility in addition to the sensitivity of each device. This is due to a more homogenous dispersion of the carbon black (CB) fillerdoi:10.1109/sas.2006.1634259 fatcat:n7ahq23mgbcnngxmslgooxqg4i
