preparation and characterization of hybrid organic-inorganic nanoparticle/pvdf blends

The blends of pvdf and hybrid organic-inorganic nanoparticles (70/30 wt%) were prepared. the hybrid nanoparticles, sio2-poly (methyl-methacrylate) (sio2-pmma) and sio2-poly (methyl methacrylate-co-hydroxyl ethyl methacrylate) (sio2–p (mma-co-hema) were synthesized via free radical polymerization. furthermore, sio2–p (mma-co-hema) was functionalized through reacting upy (ureidopyrimidinone) units including the multiple functional groups with hydroxyl groups on chains and sio2 to form the physical network of sio2–p (mma-co-upy). the chemical structure, crystallinity, and mechanical properties of the prepared blends were studied.
