Polymer Thermo-Responsive Gate Membranes

Light Responsive Polymer Membranes: A Review

In recent years, stimuli responsive materials have gained significant attention in membrane separation processes due to their ability to change specific properties in response to small external stimuli, such as light, pH, temperature, ionic strength, pressure, magnetic field, antigen, chemical composition, and so on. In this review, we briefly report recent progresses in light-driven materials ...

Composite Materials of Thermo-responsive Polymer Networks and Inorganic Nanoparticles

The focus of this work is on composite materials of inorganic nanoparticles such as TiO2 embedded within microspheres of a responsive polymeric network. Microgels of N-isopropylacrylamide (NIPAM) with interpenetrating (IP) linear chains of poly(acrylic acid) (PAAc) were synthesized to promote the incorporation of TiO2. Dynamic light scattering measurements of the IP-microgels in aqueous environ...

Fabrication of Thermo-responsive Membranes and Application Fabrication of Paper Based Thermo-responsive Membranes and Investigation for Their Use in Adsorption of Emerging Water Contaminants

CO2-Responsive polymer membranes with gas-tunable pore size.

We report a smart polymer membrane whose pore can be switched between the "closed" and "open" state just by passing CO2 and Ar in solution respectively. Compared with other stimuli, such as pH or temperature change, gas is an environmentally friendly and cost-effective stimulus for reversibly tuning the pore size and imparting the size selectivity of the membrane.

Ultrathin, freestanding, stimuli-responsive, porous membranes from polymer hydrogel-brushes.

The fabrication of freestanding, sub-100 nm-thick, pH-responsive hydrogel membranes with controlled nano-morphology, based on modified poly(hydroxyethyl methacrylate) (PHEMA) is presented. Polymer hydrogel-brush films were first synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP) and subsequently detached from silicon substrates by UV-induced photo-cleavage of a spec...
