Abstract. The mineral and elemental composition, crystal structure and particle size distribution of kaolin clays have been determined to ascertain its industrial significance. The mineral composition is evaluated by X-Ray Fluorescence (XRF), crystalline structure by X-Ray Diffraction (XRD) and particle size distribution using low angle laser light scattering (LALLS) technique. The results shows the presence of eight elements expressed in percentages in form of their oxides as: SiO 2, Al 2 O 3, Fe 2 O 3, MgO, CaO, K 2 O, TiO 2 and P 2 O 5. Five crystalline structures are revealed by XRD result. The particle size distribution shows that kaolin particles are mainly in the range of 25-35 µm, while few particles have size distribution varied between 0.4-0.75 μm. The report is found to be in agreement with other researchers.

Polymer clay nanocomposites have become a distinct field of existing research and development in the last few decades due to its magnificent properties as well as its general amazing behavior. The progress in developments on the use of modified natural and synthetic clays for designing polymer nanocomposites have dominated the polymer literature, due to their potential for improvement chemical, physical, electrical, thermal and mechanical properties compared to conventionally filled composites. This review aims to provide a description of the recent advances in the preparation of polymer clay nanocomposites and their enhanced properties and morphologies. Also, other related fields that include the types, structures and modification methods of clay.

“…Although the interest in polymer/layered silicate nano composites has ebbed somewhat recently, relatively intensive work is going on in the field and a large number of papers are published [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. The decrease of interest is caused by the fact that the nano hype has not been justified and a breakthrough has not occurred in the application of such composites.…”

Abstract. Thermoplastic polymer/layered silicate composites were prepared from the same organophilized montmorillonite (OMMT) and four different matrices, polypropylene (PP), the blend of PP and a maleated polymer (MAPP), poly(lactic acid) (PLA) and polyamide (PA) in order to study the effect of their chemical structure and interactions on composite structure and properties. The components were homogenized by extrusion and then specimens were injection molded, which were then characterized by a variety of methods. The results showed that competitive interactions among silicate layers and between the silicate and the polymer determine the extent of exfoliation, and structure. The morphology of the composites is complicated, exfoliation is never complete, besides individual silicate layers, the composite can contain a silicate network, stacks of silicate platelets and larger particles in various amounts. Several local deformation processes can take place around the structural entities as well as in the matrix. Fracture and debonding are the main particle related processes, while cavitation takes place in the polymer, at least in PA and PLA. The macroscopic properties of layered silicate composites are determined by the extent of exfoliation and interfacial adhesion that decreases upon organophilization. Increased reinforcement and improved composite properties can be achieved only by the proper control of all interactions prevailing in the composite.
