Abstract

The morphological changes and phase transitions in Cloisite organoclay at different temperatures were investigated. The structures of organoclays were divided into three types on the basis of experimental results carried out using differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy at temperature range of 30-260°C. It was found that the thinner organic layer contains two monolayers with surfactant molecules bound to the adjacent clay surfaces at 40°C. Results show that feasible interpretation of SAXS data from orgranoclays and nanocomposites must account for the complex character of layer thickness distribution in the systems.
