Experimental study demonstrates that sulfobetaine dipole orientation plays a secondary role in polyzwitterion antifouling, indicating chemical structure governs surface resistance.
-dimethylammonio)propanesulfonate). The specific fouling resistance depended on the detailed chemical structure of the polyzwitterions. Still, while clearly affecting the performance, the precise dipole orientation of the sulfobetaine group in the polyzwitterions seems overall to be only of secondary importance for their antifouling behavior.
