Here, the liquid–liquid phase separation (LLPS) in aqueous solutions containing poly(ethylene glycol) (PEG) methacrylate homopolymers is reported for first time. In this study, thermoresponse of concentrated DEGMA60 (two ethylene glycol, EG, groups) TEGMA71 (three EG groups), OEGMA300x (4.5 average varying molar masses (MM), and OEGMA50028 (nine discussed. Interestingly, temperature LLPS (TLLPS...

Abstract Polyvinylidene fluoride (PVDF) hollow fiber membranes were developed by the thermally induced phase separation (TIPS) process using a triple-orifice spinneret with solvent co-extrusion at outermost channel for applications in membrane distillation (MD). The polymer surface concentration during preparation was controlled exploiting interfacial interactions of diluent and extruded surfac...

We present a theoretical study of adhesion-induced lateral phase separation for a membrane with short stickers, long stickers, and repellers confined between two hard walls. The effects of confinement and repellers on lateral phase separation are investigated. We find that the critical potential depth of the stickers for lateral phase separation increases as the distance between the hard walls ...

Abstract Phase Transforming Cellular Material (PXCM) exhibits transformation by loading and maintains the deformed shape even after unloading compression restores original deforming in opposite direction. Conventional PXCM needs to be stressed reversely restore its shape. Bimetals, i.e., clad sheets of metals with large differences coefficient thermal expansion, can spontaneously bend response ...

Polymers that respond to small changes in environmental stimuli with large, sometimes discontinuous changes in their physical state or properties, are often called "smart" polymers. Poly(N-isopropylacrylamide), PNIPAAm, is one of the most representative smart polymer that exhibits a thermally reversible soluble-insoluble change in the vicinity of its lower critical solution temperature (LCST) a...
