| Popis: | Molecular mobility of the polymer composition in the interfacial layer at the boundary of shungite and elastomers (ethylene/propylene copolymer and natural rubber) was investigated by electron paramagnetic resonance spin probe technique. In both cases, the molecular mobility of interfacial layer is approximately one order smaller than the mobility of the bulk polymer. The layer is characterized by high polarity, which is, apparently, due to the penetration of polar molecules and groups in this layer from shungite surface. An attempt was made to estimate the thickness of the interfacial layer (2–4 nm). |
