How SiO _2 nanoparticles affect the self-organization of acrylic composites cured with UV radiation

摘要

This paper discusses homogeneous nanocomposite media that contain up to 12 wt of SiO _2 nanoparticles. The method of producing nanocomposites is based on the processes of self-organization accompanying the formation of thin polymer shells around each nanoparticle, which is the main way of obtaining an optical quasi-homogeneous material. When the initial monomeric compound is polymerized with UV irradiation, a solid transparent nanocomposite is obtained. Infrared spectroscopy and the determination of the sorption and hardness of the composites are used to confirm the presence of self-organization processes accompanying the formation of the material. The types of nanoparticle-polymer chemical bonds are investigated and determined.
