Extensive research has been conducted on the utilization of clay/PNIPAM composite nanoparticles in diverse fields, including biomedical and membrane applications. In membranes, fouling is one of the most important issues that could be solved with different ways. Smart polymers are one of the most effective ways to this problem. In this work the Clay/PNIPAM composite nanoparticles have been synthesized via radical polymerization for membrane application. The particles have been analyzed with FTIR, TGA and DLS. All results indicate a successful synthesize of Clay/PNIPAAM composite nanoparticles.
