The paper presents complex investigation results of preparation condition influence and nanocomposite polymer materials modification on their relaxation state, structure formation processes, viscoelastic, thermostable, antibacterial etc. properties. Composite films that consist of Poly(vinyl chloride) matrix filled with copper nanoparticles and obtained by exploding wire method have been investigated. Thermally stimulated depolarization method, resonance vibrating-reed method, infrared, raman, photoluminescence spectroscopy, antibacterial activity examination, derivative thermogravimetry, differential thermal analysis and other methods of thermal analysis have been used. With the help of spectroscopic and other methods, the reaction of nanofilled Poly(vinyl chloride) systems on external fields’ influence of different origin such as stable electric field, temperature field and ultraviolet has been studied. Specific stretching of Poly(vinyl chloride) structure elements under these modification factors has been found. Nanofillers function in the formation of composite complex properties has been set. It has been proved that stable thermoelectrets of Poly(vinyl chloride)/Cu systems have better electret properties than traditional Poly(vinyl chloride) materials. Besides, the obtained metal nanocomposites are quite thermally stable as regards their dynamic viscoelastic properties. It has been established that copper nanoparticles in Poly(vinyl chloride) systems fulfill the role of photostabilizer and antirad slowing down the aging process and polymer destruction in ultraviolet. The obtained metal nanocomposites possess stable indexes of high-energy radiation field absorbing capacity that allows to use them as outer radiation protection materials. High antibacterial activity of Poly(vinyl chloride)/nanoCu films to Staphylococcus aureus has been substantiated.
