This proposal is a complementary SANS study to the "Dynamics of thermoresponsive nanocomposites below and above the volume phase transition temperature" proposal also submitted in this round. This study aims to investigate the temperature dependent structure of CNT, GO and rGO containing PNIPA based nanocomposite systems nearby the volume phase transition (VPT). This phenomenon is the key for any future application of these responsive "smart" systems. Despite the increasing number of publications on such nanocomposite systems their temperature response behaviour is still poorly understood. With our experiment we expect to gain deeper knowledge on the VPT of the nanocomposites, which would lead us to a better perception of their responsive behaviour. The experiment is related to the ILL PhD project "Carbon nanoparticle - responsive gel composites for controlled delivery".
