Synthesis and characterization of ibuprofen-rectorite composites by solution intercalation method

Abstract

The ibuprofen-rectorite composites were prepared by the solution intercalation method using ibuprofen and rectorite as raw materials, and were characterized by X-ray diffraction (XRD) analysis, Fourier transform infrared analysis and scanning electron microscopy (SEM). The experimental results show that the ibuprofen is intercalated into the interlayer spaces of rectorite. The values of the (001) peaks of the ibuprofen-rectorite composite are larger than that of Na-rectorite and reach the largest when the reaction time and ibuprofen amount is 2 h and 0.36 g, respectively. The layered structure of Na-rectorite is destroyed to some extent with the intercalation of ibuprofen into the interlayer space in the structure of Na-rectorite. A part of ibuprofen in the ibuprofen Na-rectorite covers on the surface of Na-rectorite besides some ibuprofen enters into the interlayer space.
