Preparation and Humidity Control Performances of a Novel Composite Humidity Control Paper

Article Preview

Abstract:

A novel composite humidity control material was prepared, in which konjac glucomannan grafted on sodium polyacrylate with halloysite loading, adopting aluminum chloride/sodium bicarbonate system to foam, and twice foaming to form porous structure in the composites by heating at 150 °C. The resultant composites were utilized as substrates and applied in a composite humidity control paper making. Humidity performances including hygroscopicity, moisture capacity, moisture absorption and desorption rate were tested. It was found that the composite paper presents good humidity control performances even in amplified experiments.
