In‐situ atr‐ir spectroscopy reveals complex absorption‐diffusion dynamics in model polymer‐membrane‐catalyst assemblies (pcma)

HIGHLIGHTS

SUMMARY

    For instance, Y. Park et_a reported a reversible self-actuated membrane based on thermo-responsive p-NIPAM gels. The concept of stimuli responsive catalysts implies a discontinuous behavior, where the catalytic activity can be switched ‘ON` and ‘OFF` above or below a certain threshold value of the triggering variable (e. g. temperature, pH, light, etc.).[19] By adjusting the molecular diffusion to the active_site, the reaction rate can be regulated, consequently preventing the formation of by-products. This model PCMA mimics a core-shell catalyst, where the stimulus responsive polymer brushes are decoupled from . . .
