Study of the internal dynamics of soft gel - carbon nanoparticle composite systems
Environmentally sensitive hydrogels are good candidates for future targeted drug delivery or adsorption systems. Despite extensive studies in recent years their application is still highly restricted, mainly owing to their slow response rate and poor physical characteristics. One possibility to overcome these problems is to incorporate nanoparticles, i.e. prepare composite materials that combine the responsive behaviour of the gels with the mechanical stability and heat conductivity of carbon nanoparticles. Here we propose a detailed neutron-spin echo study of composite poly(N-isopropyl-acrylamide) /pNIPA/ + carbon nanotube /CNT/ systems. By this technique the internal dynamics of the composite systems will be explored as a function of the surface chemistry of the CNT incorporated. The results are expected to improve our knowledge about these delicate systems, and contribute to the development of smart responsive materials suitable for controlled (drug) delivery applications. The study is part of the ILL PhD project "Carbon nanoparticle - responsive gel composites for controlled delivery".
