Wetting behavior of polyelectrolyte complex coacervates on solid surfaces
Christopher Balzer, Pengfei Zhang, Zhen‐Gang Wang
Abstract
a first order wetting transition with second order transitions possible above a surface critical point. Applying an electrostatic potential to a solid surface always improves the surface wettability when the polycation/polyanion-substrate interaction is symmetric. For asymmetric surface affinity, the wettability has a nonmonotonic dependence with the applied potential. We use simple scaling and thermodynamic arguments to explain our results.
