Branched Copolymer Surfactants as Versatile Templates for Responsive Emulsifiers with Bespoke Temperature‐Triggered Emulsion‐Breaking or Gelation
Rajbanshi, Abhishek; Alves da Silva, Marcelo; Haslett, Niamh; Cranwell, Philippa; Cunningham, Neil; Mahmoudi, Najet; Murnane, Darragh; Pavlova, Ewa; Slouf, Miroslav; Dreiss, Cecile; Cook, Michael (2023-10-27)It has been found that the thermoresponsive behavior of emulsions stabilized by block copolymer surfactants (BCSs) can induce either gelation or emulsion break‐up with mild temperature changes. A hydrophilic, steric‐stabilizing ... -
Branched copolymer surfactants impart thermoreversible gelation to LAPONITE® gels †
Rajbanshi, Abhishek; Da Silva, Marcelo Alves; Mahmoudi, Najet; Janeczek, Agnieszka; Shaw, Allison; Dawson, Jonathan; Cook, Michael Thomas (2023-11-28)This investigation seeks to integrate LAPONITE® clay gels with thermoresponsive branched copolymer surfactants (BCSs) to develop advanced functional materials with temperature-induced sol–gel behaviour. It is known that a ... -
Combining branched copolymers with additives generates stable thermoresponsive emulsions with in situ gelation upon exposure to body temperature
Rajbanshi, Abhishek; Mahmoudi, Najet; Murnane, Darragh; Pavlova, Ewa; Slouf, Miroslav; Dreiss, Cécile A.; Cook, Michael T. (2023-04-04)Branched copolymer surfactants (BCS) containing thermoresponsive polymer components, hydrophilic components, and hydrophobic termini allow the formation of emulsions which switch from liquid at room temperature to a gel ... -
Engineered Emulsions Stabilised by Thermoresponsive Branched Copolymers for Pharmaceutical Applications
Rajbanshi, Abhishek (2023-12-07)This research work explored thermoresponsive emulsions and investigated their potential in delivering drugs through in situ gelling pharmaceutical formulations. Employing thermoresponsive branched copolymer surfactants ... -
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 ... -
Stimuli‐Responsive Polymers for Engineered Emulsions
Rajbanshi, Abhishek; Hilton, Eleanor; Dreiss, Cécile A.; Murnane, Darragh; Cook, Michael T. (2024-05)Emulsions are complex. Dispersing two immiscible phases, thus expanding an interface, requires effort to achieve and the resultant dispersion is thermodynamically unstable, driving the system toward coalescence. Furthermore, ...
