Sepiolite is a natural fibrous clay mineral with a typical molecular formula of Si12O30Mg8(OH)4(H2O)4·8H2O and has high surface area with porosity. In many studies, sepiolite has been used to increase the mechanical, physical, and thermal properties of 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. Acrylic acid monomer was polymerized with other comonomers 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 a specified temperature and relative humidity using a thermo-hygrostat. |
