Abstract

This paper describes the synthesis, structure and properties of a new layered nanocomposite which may have applications in cementitious systems. This material is one example of a new class of materials which consist of inorganic crystals containing intercalated organic polymer. The nanocomposite is synthesized by precipitating \({\text{C}}{{\text{a}}_2}{\text{Al}}{\left( {OH} \right)_6}\left[ X \right] \cdot {\text{n}}{{\text{H}}_2}{\text{O}}\left( {X = O{H^ - },CO_3^{ - 2}} \right)\) in the presence of poly(vinyl alcohol) (PVA). X-ray diffraction analysis indicates that the nanocomposite consists of calcium aluminate layers separated by interlayers containing anions, water and PVA. The intercalation of PVA can only be accomplished during crystal growth and is accompanied by an expansion in layer spacing from ∼8 Å to ∼18 Å. The nanocomposite exhibited enhanced thermal stability and when compacted into a cylinder was found to have more than twice the compressive strength than the pure calcium aluminate.
