Solvent-switchable and multi-responsive and gold-PDMAEMA nanocomposites

Au nanoparticle–polymer nanocomposites are versatile and diverse functional materials, with applications in optical,electronic, drug delivery system and sensing devices. By using poly dimethyl aminoethyl methacrylate (PDMAEMA) asa reducing agent, a facile and efficient method for producing Au-PDMAEMA nanocomposites is introduced here. PDMAEMA substrate acts either as reducing, stabilizing and shape controlling agent. The detailed structural analysisincluding UV-Vis, GPC, FE-SEM and HR-TEM were preformed for characterization. The obtained nanocomposites were examined for their responsivity to temperature, pH and CO2 and also their solubility changes in aqueous and organicphases. It showed reasonable and reproducible changes in solubility and responsiveness. This facilely prepared multiple stimuli-responsive nanocomposite could be used in bionanosensors, catalytic activities, therapeutic and diagnostic agents, electrical and optical devices
