Humidity sensing and measurement employing halogenated organic polymer membranes
Abstract
Thin films of hygroscopic, halogenated organic polymer having pendant groups of a relatively strong acidic type (e.g., sulfonic groups) and pendant groups of a relatively weak acidic type (e.g., carboxylic groups) are employed for humidity sensing by electronic, acoustics, and optical techniques.
