| During the last two decades, the introduction of welldispersed clay layers such as montmorillonite (MMT) into a polymer matrix has been proved to be extremely effective in the improvement of mechanical, thermal, and barrier properties of the polymers. 1 However, the dispersion of clay as individual platelets throughout the polymer is difficult to achieve due to strong van der Waals forces holding platelets together in conjunction with the incompatibility of the hydrophilic clay with the organophilic (hydrophobic) polymer matrix, giving way to clay agglomeration. Thus, the surface of the clays is commonly modified with a cation exchange technique to expand basal spacing and make the layered silicate compatible with polymer matrixes. Currently polymer/clay nanocomposites can be prepared by three ways such as solution mixing, melt blending, and in situ polymerization. 2 In the solution mixing method, the polymer is dissolved in an organic solvent, then the clay is dispersed in the obtained solution, and subsequently, either the solvent is evaporated or the polymer precipitated. However, the large quantities of volatile solvent necessary for this approach make it less attractive as an industrial process. Melt blending is a solvent-free method to enable mixing of the layered silicate with the polymer matrix in the molten state. However, very careful attention has to be paid to finely tune the processing conditions to increase the compatibility of clay layer surfaces with the polymer matrix. 3 In the in situ polymerization technique, the monomer, together with the initiator and/or catalyst, is intercalated within the silicate layers and the polymerization is initiated by … |
