Abstract
In this paper, the results of scientific research work are carried out to study the role of the interfacial layer in filled polymer materials using infrared and electron-paramagnetic resonance spectroscopy using the fundamentals of solid-state physics. At the same time, the authors of this work used all the rich experience of both experimenters and theoreticians working in this field of science and their own developments regarding methods for controlling the structure of these materials. It is noteworthy that the material interpreted in this work concerns composites subjected to special technological preparation, including the stage of ultrasonic dispersion of filler particles in a binder medium.
Highlights
Various branches of modern technology would benefit from a wide range of non-traditional materials, in most cases rare, expensive, and time-consuming in terms of the nature of the technological preparation
Almost all soot containing composites of polyvinylidene difluoride (PVDF), despite their compositions of organic origin, exhibit strongly broadened, inhomogeneous, and very stable electronparamagnetic resonance (EPR) signals, which are comparable in width and, in some cases, even exceed similar parameters of some classical "magnets
An attempt is made to elucidate the role of interfacial layers (IFL) in composites based on polyvinylidene fluoride (PVDF) filled with soot near the percolation threshold (vi = 0.04
Summary
Various branches of modern technology would benefit from a wide range of non-traditional materials, in most cases rare, expensive, and time-consuming in terms of the nature of the technological preparation. Unconventional materials with controlled properties include soot-filled composites, the one-sided technological preparation of which, to some extent, inhibits and limits the finding of their application in new areas. The fruitfulness of this kind of approach to studying the properties of filled polymer materials (FPM) has shown its results. The combination of optical studies of these FPMs opens up new prospects. It should be noted that the use of various configurations of samples from the studied composite and polymer materials will reduce the need for precious metals, reduce the cost of working parts made on their basis for computers, optical and magnetic technology, and expand their scope
