Engineering thermoresponsive emulsions with branched copolymer surfactants
Cook, Michael T.; Rajbanshi, Abhishek; Achampong, Daniel; Dreiss, Cécile A.; Alves da Silva, Marcelo; Porcar, Lionel; Mahmoudi, Najet; Maestro, Armando; Tummino, Andrea; Gutfreund, Philipp (2022-10-30)This study describes thermo‐rheological properties of branched copolymer surfactants (BCSs) stabilizing oil‐in‐water emulsions to generate materials exhibiting temperature‐dependent gelation with the ability to solubilize ... -
Polymer architecture dictates thermoreversible gelation in engineered emulsions stabilised with branched copolymer surfactants
Rajbanshi, Abhishek; Alves da Silva, Marcelo; Murnane, Darragh; Porcar, Lionel; Dreiss, Cécile A.; Cook, Michael T. (2022-09-26)The generation of materials that switch from a liquid to gel state upon warming can enable new healthcare technologies with improved functionality, such as in situ gel-forming materials for drug delivery to topical or ... -
Thermoresponsive Triblock‐Copolymers of Polyethylene Oxide and Polymethacrylates: Linking Chemistry, Nanoscale Morphology, and Rheological Properties
da Silva, Marcelo Alves; Haddow, Peter; Kirton, Stewart B.; McAuley, William J.; Porcar, Lionel; Dreiss, Cécile A.; Cook, Michael T. (2022-02-23)Abstract: Thermoreversible gels switch from a free‐flowing liquid state to an elastic gel mesophase upon warming, displaying the reverse transition upon cooling. While this phenomenon makes these advanced materials highly ...
