Water dispersible avermectin-layered double hydroxide nanocomposites modified with sodium dodecyl sulfate
Abstract Sodium dodecyl sulfate was utilized to modify the avermectin-layered double hydroxide nanohybrids for the preparation of water dispersible nanocomposites, resulting in the successful conversion of hydrophobic surfactant monolayer structure on the solid surface to hydrophilic bilayer. Concentrations of SDS and NaCl had important effects on the bilayer formation, and the highest suspensibility of the obtained nanocomposites reached 97.6%. All the samples were characterized using Fourier transform-infrared spectroscopy, X-ray diffraction, transmission electron microscopy, element analysis, zeta potential and contact angle measurements. It was found that the prepared materials could well control the release of avermectin, and the prepared nanocomposite would be a promising candidate for water dispersible controlled release formulation.
Research Highlights ► Water dispersible avermectin-layered double hydroxide nanocomposites are prepared. ► The presence of NaCl enhances the SDS adsorption on solid surface. ► The hydrophobic surfactant monolayer can be converted to the hydrophilic bilayer. ► The prepared nanocomposite can well control the release of avermectin.
