Study the Morphological and Mechanical Properties of Ultra-high Molecular weight polyethylene UHMWPE: Polytetrafluroethylene PTFE binary blends

Abstract

In this research, it has been investigated the effect of addition High performance polymer Polytetrafluroethylene (PTFE) on the Ultra-high molecular weight polyethylene (UHMWPE) mechanical and physical properties. It has been prepared three types of blends (95:5, 90:10 and 85:15) of UHMWPE: PTFE by compression method. Stress-Strain curves of polymer blends have been showed that higher ultimate strength and Young modulus were at 95:5 and decreased gradually as wt. % PTFE increased. FTIR inspection has been also accomplished. Finally SEM results showed incompatibility between the polymers with presence of boundaries between the binary polymers phases.
