Abstract
In this paper, switch-type humidity sensors based on PAA (polyacrylic acid) and its copolymers were examined. The humidity sensing properties of these polymers, such as hysteresis, response time, water resistivity and long-te rm stability were investigated. The factors which influence the humidity se nsors' inflection point were investigated experimentally as well. The resul ts show that, the inflection point of the humidity sensors varies with the content of crosslinking agent and the sample composition. In particular, hu midity sensors based on Sample E and B show good property and stability. (C ) 2000 Kluwer Academic Publishers.
