Characterization and Preparation of Polyamide 66/OV-POSS Nanocomposite Fibre

摘要

Poly hexamethylene adipamide (PA66) nanocomposite fibers were prepared by using PA66 and polyhedral oligomeric silsesquioxanc (POSS). Rheological behavior, mechanical and thermal properties were characterized. Rheological study showed that a small amount of POSS can improve the flowing property and reduce PA66 viscosity. The onset decomposition temperature was improved with the addition of POSS as indicated by TGA analysis. Nearly all the mechanical properties were found to be increased with the adding of POSS. However, it was seen that higher POSS loading would not improve fiber performance due to serious of agglomeration.
