Surface patterning was aroused much interest because of its great importance in
the applications to microfluidic devices, etc. In this paper, we report a novel
method to realize surface patterning on an electro-sensitive
polymerpoly(2-acrylamido-2-methylpropanesulfonic acid). Through imposing the
external electrical field utilizing a copper mesh film used in SEM as electrode,
the film exhibits different properties in the areas that contact or not contact
with the metal part of the mesh, which resulting in a pattern being the same as
the mesh. This effect can be well explained by the conformational change of the
polymer chains in the electric field.
