Layered polymer-kaolinite nanocomposites
Source abstract
Abstract
Kaolinite (K) was reacted with liquid dimethyl sulfoxide (DMSO) producing K(DMSO)0.4. Highly ordered polymer/kaolinite materials were obtained by displacement of DMSO molecules in the K(DMSO)0.4 intercalate by polyethylene oxide (PEO) or bacterial polyhydroxybutyrate (PHB), both in the melt state at 130°C and 180°C, respectively. The hybrid nanocomposites obtained were characterized by powder X-ray diffractometry (PXRD), Fourier Transform Infrared spectrometry (FTIR) and thermal analysis (simultaneous TG/DSC). The obtained results are consistent with the total replacement of DMSO molecules by the macromolecular linear chains that lie flat building a monolayer of the polymer in the interlayer space of kaolinite. The stoichiometry of the compounds estimated from the TG/DSC measurements are: K(DMSO)0.40±0.02, K(PHB)0.82±0.02, K(PEO)3.40±0.02.
