KAOLINITE-UREA INTERCALATES FOR PVC NANOCOMPOSITES

Popis výsledku v původním jazyce

Using clay as a filler in polymers we obtain so called polymer/layered silicate nanocomposites which exhibit many unique properties. The mechanical as well as chemical properties, thermal stability, gas permeability, and flammability can be substantiallyimproved. Very important is funcionalization of the surface of filler. So, the intercalation of kaolinite by urea was performed. Untreated and treated kaolinite samples were examined by X-ray diffraction (XRD). Samples intercalated with urea and subsequently exfoliated during washing exhibit a variable intensity of the 001 diffractions of kaolinite (K) and the presence of interstratified intermediate kaolinite phase was also approved. For the PVC/kaolinite-urea nanocomposites the suspension type of PVCwith K value 60 was used. PVC/kaolinite compounds were prepared by the melt intercalation method. Pure kaolinite, urea intercalated kaolinite and exfoliated kaolinite after washing of urea from kaolinite-urea intercalate were used as the
