제목 PETG/CLAY NANOCOMPOSITES WITH SUPERCRITICAL CO2 ASSISTED TWIN SCREW EXTRUSION
초록 A twin-screw extrusion process for PETG/clay nanocomposites using supercritical CO2 was studied. The properties of PETG/clay nanocomposites are investigated by rheometer, thermal analyzer, permeability tester. The effects of clay contents and CO2 feed rate on the rheological and barrier properties of PETG/clay nanocomposites are presented. The results show that the rheological and thermal properties of the nanocomposites increase with the addition of clay. From the permeability test of nanocomposites, the barrier properties also increase. Moreover, the analysis of the nanocomposites also reveals that the use of supercritical CO2 leads to an increase of the barrier properties. From the results above, we strongly suggest that the use of supercritical CO2 assisted twin-screw extrusion is an effective way to improve the superior properties of PETG/clay nanocomposites.
