Engineering thermoresponsive Branched copolymer surfactants: Polymer structure at oil/water interface
Thermoresponsive emulsions are promising materials that offer bespoke rheological behaviour triggered by mild temperature changes and have applications in advanced therapeutics, tissue engineering and soft robotics. We have designed superior thermothickening materials based on "engineered emulsions" stabilised by branched copolymer surfactants (BCS). These BCS are branched copolymers comprising thermoresponsive polymers terminated by hydrophobic chain ends, which are grafted with hydrophilic blocks. BCS hydrogels structure and properties depend on how the components interact at the nano-scale level, which are dictated by its structural organization. There is a lack of understanding on how the different BCS domains interact at the interface, which complicates the BCS engineering. We propose to use Neutron Reflectivity to achieve an understanding of the structure of these new constructs at the liquid-liquid interface, both above and below the LCST. These experiments will give us critical insight into how the different BCS domains interact with the oil/water phase, allowing us to correlate bulk and nanoscale properties to better fine-tune the final thermothickening emulsions.
