Abstract In this study, poly(styrene-co-methacrylate)Na ionomer containing low molecular weight polyethyleneglycol(PEG) with different molecular weight(2000, 4000, 6000). And the surface of the ionomer film was examined using a scanning electron microscope(SEM). Experimental results were also compared with PSMANa ionomers having different ion contents including PEG(6000, 30 wt%). It was found that particle size decreased with increasing ion contents of pure PSMANa ionomer, and the surface of the ionomer films was smooth. In the case of the 3.2 mol% PSMANa ionomer containing PEG with different molecular weights, the particle size was in the following order: PEG6000> PEG4000> PEG2000. In the case of the sample containing PEG6000 compound, cracks occurred on the surface of 3.2, 5.7 mol% PSMANa ionomer film. It was also observed that the crack size of 5.7 mol% ionomer were larger than 3.2 mol% ionomer.
