Polyamide 6/Polyurethane/Graphite Composites Prepared by Anionic Polymerization Process.Ⅰ. Mechanical Properties
Polyamide 6/polyurethane/graphite composites have been prepared by anionic polymerization process.The effect of graphite concentration on mechanical properties of the composites was investigated.The test results show that with increment of graphite content,tensile strength of the composites increases firstly,and then decreases,while notch impact strength decreases.The change of mechanical properties of the composites is attributed to the dispersion of graphite,the interfacial properties between the matrix and graphite and the nucleation effect of graphite.In addition,the relationships between loss factor(Tan δ),storage module(E) and temperature were investigated using Dynamic Mechanical Analysis(DMTA),and the morphological characteristic of the composites were studied using Scanning Electronic Microscope (SEM).
