Abstract
The morphology of surfactant–polymer complexes formed in two dimensions has been studied. We found that the morphology of hexadecyltrimethylammonium bromide – modified partially hydrated polyacrylamide (CTAB–MHPAM) complexes transferred to mica from the interface between air and MHPAM aqueous solution shows pearl necklace structures, and it is orientationally aligned. On the addition of salt, this structure is altered to the dendritic fractal structure with a smaller fractal dimension about 1.1 ± 0.01. These structures have potential applications in the fabrication of materials in the nanoscale. The mechanism of the formation of different patterns has been discussed.Key words: morphology, Surfactant–polymer complexes, Dendritic fractal structure.
