The aim of the research: to prepare new processing materials in the nano size that have sensitive properties towards temperature and pH and contain silver nanoparticles as well as silica. Results: Silver/silica nanoparticles (core/wall) were prepared using a simple method in one step and using a low concentration of dextran as a reducing and stabilizing agent. As well as using ascorbic acid as an agent. The prepared granules were characterized using X-ray diffraction and electron microscopy. The nanogels that respond to the change of both temperature and pH were prepared by polymerization of isopropyl acrylamide with pullulan.Silver/silica nanoparticles were used during the steps of preparing the pullulane nanogels to obtain a pullulane/silver/silica composite.
