Abstract
Films of differently modified PVA (polyvinyl alcohol), TA (phthalocyan inosilicon) and Nafion in different ionic forms (H+, Li+, and Na+) hav e been prepared by using casting methods. Impedance changes of the fil ms with relative humidity are examined. The results demonstrate that t he content and hydrophilicity of the hydrophilic group in PVA, ionizat ion of TA, and the cation in Nafion have significant effects on sensin g properties of the films.
