Effects of Nano-Attapulgite on the Structure and Properties of Thermal-Plastic Polyurethane Composites

摘要

Attapulgite (AT) nanofiber reinforced polyurethane (PU) composites have been prepared by direct blending. The result of FT-IR demonstrated AT has an effect on the carbonyl of hard domain and intensive the hydrogen bonding between molecular chains. Compared to the pristine PU, the AT/PU nanocomposites not only exhibited higher thermal stability properties, but also the dramatically improved tensile mechanical properties.
