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
