Special Issue Information

Dear Colleagues,

In the last three decades, there has been a steady increase in interest in studying the processes of obtaining, processing, and applying polyconjugated systems, as well as in the search for approaches to obtaining new functional composite materials with the participation of conductive polymers. Conductive polymers and composite materials on the basis thereof are used for the manufacture of sensors, actuators, electrically conductive paints, luminescent systems, antistatic and anticorrosion coatings, membranes, and various functional biomaterials. Special attention should be paid to the fields associated with the preparation of nanoparticles of conductive polymers and their use for the formation of nanocomposites known for a complex of special properties. Another important area of application for the conductive polymers is in the area of coatings for various surfaces, both aimed at improving adhesion characteristics and imparting other special properties. Any manuscript that addresses aspects of the preparation, study of the properties and use of conductive polymers is suitable for a special issue. The manuscripts that establish the relationship between the properties of composite materials containing conductive polymers and the conditions for their preparation, as well as articles on the synthesis of conductive polymers that contribute to expanding the scope of their application are particularly welcome. Any manuscripts that address the issues of obtaining, the properties and the application of composite materials based on polyaniline, polypyrrole, polythiophenes, polyphenylenes, polyacetylene and related polymers are also relevant. This special issue is intended to become a platform for the rapid publication of high-quality original and review articles on any composite materials on the basis of conductive polymers.

Abstract
A method has been developed for producing an epoxy composition based on a low-viscosity epoxy-resorcinol resin, a phosphazene-containing curing agent, isophoronediamine, and thermally expanded graphite as a filler.

A method has been developed for producing an epoxy composition based on a low-viscosity epoxy-resorcinol resin, a phosphazene-containing curing agent, isophoronediamine, and thermally expanded graphite as a filler. The degree of cure and the absence of side reactions during the curing process were confirmed using IR spectroscopy. The influence of the content of phosphazene-containing curing agent and filler on the physico-mechanical properties of the composition, its fire resistance, and antistatic properties were studied. Using the UL-94 HB horizontal burning test, it was found that the addition of 10 and 20 wt. % phosphazene-containing curing agent (relative to isophoronediamine) reduces the burning speed by 10 times compared to a sample without phosphazene. The addition of a filler to a composition containing phosphazene reduces the burning speed by 25 times compared to a composition without phosphazene and imparts antistatic properties to the epoxy composition, as evidenced by the specific volume electrical resistance of the order of 101 Ohm·m. Phosphazene-containing curing agent had no statistically significant effect on specific volume electrical resistivity (p > 0.05). Tests of physico-mechanical and adhesive properties (tensile strength, compressive strength, water absorption, water solubility, abrasion resistance, and adhesive strength) of filled epoxy compositions with 10 and 20 wt. % phosphazene-containing curing agent demonstrated that these properties met the requirements for floor coverings in construction and parts of electrical devices.

Nitrogen-containing polyphenylene type polymers containing pyridine rings were synthesized. The polymer-forming reaction is based on the interaction of diacetylarylene and triethylorthoformate with the formation of a pyrylium salt and subsequent treatment of the intermediate product with ammonia. The optimal ratios of the reagents for the formation of the pyridine fragment were determined. The mechanism of the main reaction is discussed. The formation of the pyridine ring and phentriyl (1,3,5-triphenylsubstituted benzene) fragments was confirmed using 1H NMR data of the example of model reactions. After heating at a temperature of 450 °C, when a more complete polycondensation process occurs, the polymers reach high values of thermal characteristics—10% weight loss in an inert atmosphere corresponds to 600 °C. The structure of the synthesized polymers was confirmed using elemental analysis, IR, XPS, and EPR spectroscopy. The conjugation length in cross-linked polyphenylene pyridines can be controlled by varying the arylene bridge groups between the phentriyl fragments, which opens up opportunities for the development of new composite materials for electrical applications.

Thermoelectric (TE) materials are capable of realizing the direct conversion between heat and electricity, holding a giant prospect in the sustainable development of modern society. Conductive polymers (CPs) are suitable for the preparation of TE materials given their low-cost, lightweight, flexible, and easy processing properties. With the accelerating pace of flexible composite development, there is intensive interest in their emerging applications in various aspects such as wearable electronics and thermoelectric sensors. In order to further improve the thermoelectric properties, a series of new methods have been proposed to prepare conductive polymer-based thermoelectric composites and improve their thermoelectric properties. In this review, we discuss the compositing methods, properties, and applications of conductive polymer-based TE composites. The challenges and future development directions in the design and application of conductive polymer matrix composites are also pointed out. Full article
