We report a facile, versatile, and novel approach for the design of ultralow fouling membranes via mussel-inspired molecular functionalization and zwitterionization. Using mussel-inspired polydopamine (PDA) coatings on polysulfone microporous membranes, active molecules with tertiary amine functionality (N,N-dimethylethylenediamine (DMDA)) were grafted via Michael addition through primary amine groups...
Low-pressure plasma treatments of PTFE films using sulfur dioxide (SO 2 ) as process gas were carried out in order to insert functional groups containing sulfur and oxygen into the inert polymer surface. By modifying the plasma parameters: gas flow rate, power and treatment time, the best plasma conditions for a surface modification could be found. An increase of the wettability, in terms...
