“…Переваги використання диференціального методу. На сьогодні існує ряд проведених досліджень та патентів, що стосуються підвищення ефективності електроємнісного методу сканування з використанням плоского перетворювача та його застосування у різних сферах діяльності людини [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Однак в дослідженнях, що стосуються підвищення ефективності застосування методу в рамках цивільного розмінування [17,18], не приділялась увага перспективі використання диференціальної схеми вимірювання та перетворювача відповідної конструкції, та вплив такого підходу на результати сканування.…”

“…This also applies to the PCMs, which are inherent in the above 2 Advances in Polymer Technology distinctive features. So, intellectual (smart) PbMs are able to respond to changes in operating conditions or "warn" about the occurrence of emergency situations [3][4][5]. Currently, IPCMs are manufactured on the basis of various types of sensors and nanomodifiers, alloys with magnetic properties, fiber-optic and piezoelectric sensors, and a number of other materials.…”

“…At the same time, researchers are developing designs similar to the "biological models" of intellectual structures existing in nature. Moreover, the concept of IS is often associated with nanotechnology, where these ISs are used [3][4][5]. The above aspects of IPCMs are the subject of a brief review of this article.…”

The various aspects of physicochemical modification of the components of structural materials of functional application based on classical composites and nanocomposites are analyzed. Potential applications of such materials are briefly described. Ultrasonic cavitation treatment is considered as a basic method of physical modification when obtaining the indicated classes of composites. The influence of ultrasonic treatment modes on the technological and operational properties of reactoplastic polymers, as well as on the hardening of reinforced composites based on them, is investigated. Technical means of ultrasonic cavitation processing of liquid binders and polymer composites based on them are briefly described. An effective spectrum of interrelated structural and technological parameters of ultrasonic treatment has been characterized, which is established by calculation and experimentally-statistically. The design issues of the technological processes of obtaining polymer composites of functional application are analyzed. The efficiency of creating carbon fiber composite materials, as well as the prospects for creating of these materials based on reinforcing fabric with nanomodified fillers, is described. The methods of obtaining functional nanomodified carbon-composites with improved physicomechanical and operational properties, in particular with increased strength and electrical conductivity, are characterized. The effectiveness of the ultrasonic treatment and production of nanomodified thermoplastic composite materials by extrusion method is considered. Some issues of forming products from intelligent polymer composites are analyzed. The results of the survey can be used in the design of advanced technologies for the creation of functional polymer composites of functional application.

“…We should also mention another class of innovative PCMs, namely, intellectual (smart) PCMs [18][19][20], including NM PCMs [21]. PCM intellectualization is achieved by modifying polymer composites with components that contribute to the transformation of such materials into materials that self-diagnose and adapt to external temperature-force effects.…”

Various aspects of the methods of physical and physicochemical modification of components of filled thermoplastic composite materials are analyzed, aimed at improving the surface properties of the fillers and the technological properties of the polymer matrix during their interaction. It is noted that the improvement of the interfacial interaction of the components of polymer reactoplastic composites, including adhesive strength, is a key factor for improving the reliability of the cured filled composite. As a promising area of research, a modification of the surface of the reinforcing fibrous filler and the technological characteristics of the liquid polymer binder, aimed at increasing their contact properties in the composite, was chosen. The effectiveness of the physical method of modifying the components of composites in the form of low-frequency ultrasonic processing is described. The peculiarities of cluster formation and physicochemical modification of epoxy polymers filled with dispersed fillers are analyzed. Attention is focused on the effectiveness of ultrasonic processing in the cavitation mode for deagglomeration and uniform distribution of nanoparticles in a liquid medium during the creation of nanocomposites. Experimentally confirmed is the improvement of the technological properties of liquid epoxy polymers, modified by ultrasound, used for the impregnation of oriented fibrous fillers, as well as the improvement of the physicomechanical properties of the sonicated epoxy matrices. Some issues of biological modifications of components of polymers for functional application are briefly reviewed.
