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.
