Abstract

Composition effect on the phase morphology in polyethylene (PE) with polyamide (PA) blends was investigated by pattern analysis of scanning electron micrographs. The average diameter denoted as d~g~ is defined to discuss the morphology of the blends and further, different fractal dimensions, D~M~ and D~N~, were introduced to characterize the phase morphology. Scale function S~N~(r) and S~M~(r) are defined to study the selfsimilarity of the phase morphology. The plots of S~N~(r)/S__~N~(r)m (the maximum of S~N~(r)) versus r/rm (the maximum of r) and S~M~(r)/S~M~__(r)m (the maximum of S~M~(r)) versus r/rm showed the selfsimilar formation of the phase pattern. Furthermore, we calculated the fractal dimension D of different PE/PA blends. The results showed that the fractal dimension was an effective parameter to describe the spacial distribution of dispersed particles. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
