Polymer composites containing carbon nanomaterials have attracted considerable attention of researchers due to their unique physicochemical properties and a wide range of applications. In particular, composite materials based on epoxy resin and polyethylene doped with carbon nanoparticles demonstrate improved mechanical, electrical, and optical characteristics, making them promising for use in the aviation, electronics, automotive, and biomedical industries. One of the key aspects of the investigation of such composites is the study of their structural features and interactions between the polymer matrix and the filler. An important tool for this is a set of spectroscopic-analysis methods, in particular, vibrational spectroscopy, which allows obtaining information about the molecular structure and interfacial interactions in materials. The study of Raman scattering (RS) of light and infrared (IR) absorption spectra allows us to assess changes in intramolecular dynamics and the nature of bonds in the polymer matrix, taking into account the influence of carbon nanofillers. This article examines the features of the vibrational spectra of epoxy and polyethylene composites with carbon nanomaterials, analyses their effect on the polymer-matrix structure, and discusses possible mechanisms of interaction between the composite components.
KEY WORDS: polymer nanocomposites, carbon nanotubes, graphene nanoplatelets, FTIR spectroscopy, Raman spectroscopy
