Abstract: The structure images of hydrophobic associated polymer (AP-P4) solution with different concentrations on mica slice is studied using atomic fore microscopy (AFM). The effect of the concentration on the structural image is confirmed definitively. It means that the images are quite different in different concentrations. When AP-P4 solution concentration is at 200 mg/L, its structure mainly appears in form of aggregates; at 500 mg/L, it occurs in form of spatial reticular structures. This method is helpful to understand the molecular images and the gel structures of AP-P4 and to study the solution structure of the polymers.

Key words: atomic force microscopy (AFM), polymer, structure, shape, image
