Sepiolite is one of many naturally occurring nano needle-shaped clay materials, composed of hydrated magnesium silicate, and it has been used to increase the mechanical, physical, and thermal properties of a polymer. In this study sepiolite was used as a filler component in superabsorbent polymer composites to regulate the moisture absorption capability of a hydrophilic polymer. Water soluble monomers were polymerized in the presence of sepiolite dispersion, and the products were isolated to make sepiolite/polymer composites. Moisture absorption performance of the composites were evaluated at constant temperature and relative humidity using a thermo-hygrostat. |
