Title

Exploring complex internal dynamics in thermoresponsive nanocomposite gels

Abstract

"Smart", responsive hydrogels are promising candidates for actuators, sensors and biomedical applications such as pressure sensing or artificial cartilage. However, their application is often restricted by physical limitations. Composite systems offer a means to overcome these problems. This proposal aims to study the internal dynamics of carbon nanoparticle (CNP) filled responsive hydrogel systems based on poly-N-isopropyl-acrylamide (PNIPA) above the volume phase transition (VPT) temperature. Our proposed experiment will further deepen our knowledge of the diffusive properties of the nanocomposite systems above the VPT, and provide a better perception of the effect of the different CNPs on the dynamics of these gels on the microscale.
