摘要
Over the last few years, Montmorillonite (MMT) was widely used as a special inorganic material for preparing Polymer/MMT nanocompsites. MMT is a clay imineral consisting of stacked silicate sheets whose thickness is about 10A. Through intercalation a large number of polymer-clay nanocomposites have been prepared such as Nylon-clay hybrid [1], PS-clay hybrid [2], Poly (methyl methacrylate) (PMMA)-clay hybrid [3], etc.In this article, the synthesis and properties of Poly (acrylic acid/acrylamide)/MMT hybrid (PAAAM/MMT) were studied. X-ray diffraction and Transmission electron microscopy were used to characterize the hybrid material. DSC has been used to study its property. Results showed that the intercalating reagents have entered the space of MMT's layers and enlarged them. At the same time, the MMT dispersed homogeneously in acrylic acid and acrylamide monomers that allow MMT to disperse in PAAAM matrix in the monolayer form.
