Clay was organically modified with one kind of ionic liquild. Organical clay obtained was used to prepare poly(propylene) (PP)/clay nanocomposites by solution blending. Flourier transform infrared (FTIR), wide-angle X-ray diffraction (XRD) and thermogravimetric analysis (TGA) revealed that the ionic liquild was loaded in the galleries of organically modified clay. TGA result show the thermal stability of organically modified clay was superior to clay. XRD patterns indicated that the d-spacing of clay layers increased to 2.96 nm from 1.22 nm of clay. XRD patterns of PP/clay nanocomposites show that clay layers were dispersed in PP matrix by nanometer size.

The present review aims to summarize the research efforts undertaken in the last few years in the development and testing of hydrogel-clay nanocomposites proposed as carriers for controlled release of diverse drugs. Their advantages, disadvantages and different compositions of polymers/biopolymers with diverse types of clays, as well as their interactions are discussed. Illustrative examples of studies regarding hydrogel-clay nanocomposites are detailed in order to underline the progressive researches on hydrogel-clay-drug pharmaceutical formulations able to respond to a series of demands for the most diverse applications. Brief descriptions of the different techniques used for the characterization of the obtained complex hybrid materials such as: swelling, TGA, DSC, FTIR, XRD, mechanical, SEM, TEM and biology tests, are also included. Enlightened by the presented data, we can suppose that hydrogel-clay nanocomposites will still be a challenging subject of global assiduous researches. We can dare to dream to an efficient drug delivery platform for the treatment of multiple affection concomitantly, these being undoubtedly like ”a tree of life” bearing different kinds of fruits and leaves proper for human healing.

Different polyesteramides hyperbranched polymers (HPEA1-6)/montomorillonite clay (MMT) nanocomposites were prepared with three different loading contents of clay (4, 10, and 15 wt%). The obtained nanocomposites were characterized via XRD, thermal analyses, and TEM. Generally, intercalation behavior was observed. The hyperbranched polyesteramides (HPEA1-6) were originally prepared by the bulky reaction between maleic anhydride (MAn), succinic anhydride (ScAn), and phthalic anhydride (PhAn) with either diethanolamine (DEA) or diisopropanolamine (DiPA). The resulting hyperbranched polyesteramides (HPEA1-6) were characterized by GPC, IR,1H-NMR, TGA, and DSC.
