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.
