摘要: Cationic nanoclays were treated by ion exchange with various ionic liquids (ILs) containing cations and anions of different structure and/or molecular weight in order to investigate the effects IL cation chain length on extent clay dispersion, intercalation, thermal stability. The modified clays imidazolium-, pyridinium-, phosphonium-based characterized Fourier transform infrared spectroscopy, thermogravimetric analysis, X-ray diffraction. Although stability pure ILs was mostly controlled type anion present, high temperature clays, at loadings achieved this work, not significantly dependent type, structure, or size cation. latter parameters, however, significant importance controlling degree dispersion during melt compounding polypropylene (PP). Basal spacing increased proportionally intercalated showed little change PP composites. commercial organoclays shown be less thermally stable than they exhibited larger basal better characteristics polyolefin matrix; same matrix as phosphonium clays.
