High pressure method was used for the first time to produce rectorite clay (REC) /phenolic resin (PF) and organic rectorite clay (OREC) /phenolic resin and montmorillonite ( MMT ) /phenolic resin (PF) nanocomposites. The structure of the material phase was studied by X-ray diffraction ( XRD ), transmission electron microscopy (TEM), Fourier transform infrared ( FT- IR) spectroscopy, thermogravimetric analysis ( TGA ), and atomic force microscopy (AFM). The experimental results show that intercalated clay/resin nanocomposites could form under normal temperature and high pressure conditions by the intercalation of polymeric molecules rather than interlayer polymerization.
