Thermoresponsive gels are widely used for tissue engineering and drug delivery applications. They consist of a thermoresponsive polymer that self-assembles in a 3D network when increasing the temperature above a critical temperature. We have recently designed and synthesised a series of novel triblock amphiphilic thermoresponsive polymers that hold great promise as biocompatible gels for biomedical applications. Here, we propose to use rheo-SANS to simultaneously investigate the self-assembly and the macroscopic rheological behaviour of such polymers across a range of different temperatures and concentrations. To the best of our knowledge, this is the first rheo-SANS study on methacrylate-based ABC triblock copolymers. Its findings will feed into several projects of the PI's and the co-I's groups, providing essential insights for the design of a new class of thermoresponsive gels.
