Redox-responsive polymeric membranes via supermolecular host-guest interactions
2015 (English)In: Journal of Membrane Science, ISSN 0376-7388, Vol. 480, 139-152 p.Article in journal (Refereed) Published
Redox-responsive materials have attracted much attention, and redox-responsive membrane is strongly desired since enormous numbers of redox reactions carry out in living systems. Herein, a novel polymeric membrane with redox-resposive hydraulic permeability is fabricated by introducing a reversible redox-responsive system based on the host guest complex between ferrocene (Fc) and beta-cyclodextrin (1 CD) into polyethersulfone (PES) membrane. As the result of reversible radox-responsive formation or deformation of the complex, the water flux for the membrane with 18.3 wt% redox-responsive materials was 270 mL/m(2) mmHg h in original state, while increased to 1022 mL/m(2) mmHg h in oxidation state and decreased to 538 mL/m(2) mmHg h in reduction state. In addition, the results of water contact angle, surface zeta potential and the gas flow/liquid displacement confirmed that the origin of the reclox-responsive hydraulic permeability were the change of the pore size and porosity for the modified membranes. The redox-responsive membranes have great potential to be utilized in the Fields of chemical detection, drug delivery, biological treatments and so On.
