PROCESSING OF PET NANOCOMPOSITES WITH DIFFERENT PERCENTAGE OF SURFACTANTS USING TWIN SCREW EXTRUSION TECHNOLOGY

摘要

Poly(ethylene terephthalate) (PET) nanocomposites and two organoclays with different content of the same surfactant were blended in a twin screw extruder. The effect of the amount of surfactant on the microstructure and isothermal crystallization kinetics of the filled and unfilled systems was studied. The isothermal data from differential scanning calorimetry was analyzed using the Avrami equation. The spherulitic structure was observed using scanning electron microscope. It was found that the amount of the surfactant significantly affected the crystallization and microstructure of PET/organoclay nanocomposite.
