pH-amplified exponential growth multilayers : a facile method to develop hierarchical micro- and nanostructured surfaces

We report a direct method to amplify the exponential growth of multilayers significantly by the alternating deposition of polyethylenimine (PEI) at high pH and poly(acrylic acid) (PAA) at low pH. The alternating pH switches the degree of ionization of the polyelectrolytes in the multilayers, which e...
