Preparation and application of rosin@apatite hybrid material with new natural surfactants based on in-situ reaction by sol-gel method

Abstract

Due to the combination of organic and inorganic advantages, organic@inorganic hybrid materials have important applications in drug-loading, water-treatment and other fields. Rosin@apatite (AP) hybrid materials with various morphologies were designed and obtained by in-situ reaction using two novel rosin-based phosphoester surfactants as organic phosphorus sources. The hybrid materials combined multi-ring, multi-electron groups of natural rosin diterpene and strong physical adsorption properties of apatite. Block and sheet rosin@AP hybrid materials were prepared by sol-gel method with mild reaction conditions. The materials have excellent adsorption capacity of phenol (9.2 mg/g) and loading capacity (492 mg/g) of adriamycin (DOX) induced by π–π stacking interaction with rosin bases. The content of rosin based organic materials in hybrid materials is as high as 47.5% by thermogravimetric analysis. The formation mechanism of hybrid materials was speculated in detail.
