Effect of OMMT on Crystallization and Compatibility of PE-HD/PA6 Alloys

doi:10.19491/j.issn.1001-9278.2010.01.008

Abstract

Abstract: The microstructure and crystallization behavior of high density polyethylene/polyamide 6/organic montmorillonite (PE-HD/PA6/OMMT) nanocomposites were characterized using XRD, TEM, SEM, and DSC. Without OMMT, PA6 dispersed in PE-HD as spherical particles with diameters between 30 and 40 μm. When OMMT of 3 phr was introduced, the interfacial tension between PE-HD and PA6 phases was reduced and the size of PA6 domains was decreased to about 10 μm. OMMT also improved the barrier properties of PE-HD/PA6 alloys to organic solvents. With increasing OMMT content, more γ crystals were formed in PA6.

Key words: high density polyethylene, polyamide 6, alloy, organic montmorillonite, crystallization, compatibility, dispersion
