TPU/NANOCLAY COMPOSITES PRODUCED VIA REACTIVE EXTRUSION

摘要

In this study, reactive extrusion was used to polymerize a typical thermoplastic polyurethane in situ with an organically modified layered silicate. Depending on the incorporation method, varying degrees of nanoclay dispersion were achieved. However, even with good nanoclay exfoliation, significant improvements in tensile and barrier properties were not achieved. Compared to analogous composites produced via melt compounding, composites produced via reactive extrusion exhibited superior properties.
