Nanorods assembly of polystyrene under theta condition

Different polystyrene (PS) nanostructured materials have been constructed through the template technique in its theta solution with different concentrations. Polystyrene nanorods can be obtained at theta temperature in cyclohexane with a concentrated solution of C = 140.0 g/L. Below this concentration, mixed PS nanotubes and rods or pure nanotubes are obtained. The measurements from scanning electron microscope (SEM) and transmission electron microscope (TEM) confirmed all the rod or tubular structure.
