The ability of water-soluble ammonium-based zwitterions (ZIs) to form aqueous biphasic systems (ABS) in the presence of aqueous solutions of salts is disclosed here. These systems are thermoreversible at temperatures close to room temperature and further allow the design of their thermal behavior, from an upper critical solution temperature (UCST) to a lower critical solution temperature (LCST)...

A series of peptide-based triblock copolymers cons i s t ing of poly(γ -benzy l -L -g lu tamate) -b -po ly (dimethylsiloxane)-b-poly(γ-benzyl-L-glutamate) [PBLG-bPDMS-b-PBLG] were synthesized using ring-opening polymerization (ROP). The chemical structure and degree of polymerizations were evaluated by H NMR. These triblock copolymers form thermoreversible gels in toluene with critical gel conc...

Homopolymers of N-acryloyl glycinamide were prepared by reversible addition-fragmentation chain transfer polymerization in water. The formed macromolecules exhibit strong polymer-polymer interactions in aqueous milieu and therefore form thermoreversible physical hydrogels in pure water, physiological buffer or cell medium.

Thermoreversible food materials are suitable for hot-extrusion 3D printing (HE-3DFP) to customize designs and enable on-demand production. A challenge of HE-3DFP is control the material phase transition such that it melts allow flow extrusion rapidly solidifies afterwards obtain stable printed structures. We here report on use thermal imaging simultaneously monitor cooling deformation common th...

A novel hyperbranched polymer gelator has been synthesized, which can self-assemble into the thermoreversible physical gel in DMF, DMAC, pyridine, DMSO or NMP with the driving force of hydrogen bonds among amide and amine groups of the highly branched macromolecules.

Judicious control over the mean degree of polymerization each block in a amphiphilic diblock copolymer ensures that corresponding worm gel exhibits thermoreversible (de)gelation behavior, as judged by TEM, SAXS and rheology studies.
