Organic–Inorganic Incompletely Condensed Polyhedral Oligomeric Silsesquioxane-Based Nanohybrid: Synthesis, Characterization and Dye Removal Properties

ABSTRACT

A nanocomposite was developed from organic–inorganic hybrid of incompletely condensed polyhedral oligomeric silsesquioxane nanoparticles and poly (acrylamide-co-hydroxyethyl methacrylate) with properties of hydrophobicity of incompletely condensed polyhedral oligomeric silsesquioxane and dye adsorption capacity of the copolymer. The as-prepared nanocomposites were characterized by X-ray diffraction, scanning electron microscopy, and Fourier transform infrared spectroscopy. The synthesized hybrid nanocomposite acquires extraordinary water remediation property after the removal of toxic dye from aqueous solution. Conditions for the adsorption of dye by the hybrid nanocomposite have been also optimized. In addition, the adsorption mechanism was studied.
