Composite Materials Based on Graphite and Polyhydroxy Ether of Bisphenol A

Abstract

Composites based on polyhydroxy ether and graphite of industrial grades MPG and GL were produced and investigated. Methods were developed for introducing graphite into the polymer matrix. It was shown that preliminary oxidative surface treatment of the graphite leads to the selective adsorption of monomers on its surface, which lowers the rate of the reaction in situ during the production of the composites. It was shown that the method for introducing the graphite and the amount of the latter have a considerable influence on the properties of the composite obtained.

Synthesis of New Thermostable Polyhydroxyester on the Basis of 2- Hydroxypropyl-1,3-Bis-Carboxymethylesterosulfoimide of Saccharin-6-Carboxylic Acid

“…Unlike low molecular weight epoxypolymers, the high molecular weight ones are thermoplastic linear polymers with high content of the hydroxyl groups. The production of such polymers was mastered on an industrial scale in some countries [6][7][8].…”

Investigation of the Process of Finishing of Carbon Fibers of Various Brands with Oligomers and Polymers of Various Chemical Structures

“…One of the most common approaches to improving the compatibility of carbon fiber with a polymer matrix is based on the treatment of the surface of hydrocarbons by activators [3][4][5] and the subsequent application of various finishing agents, which are typically organic oligo-and polymers. In such composites, the dressing performs two tasks: it protects the fiber from undesirable effects during subsequent processing and plays the role of an adhesive that increases the forces of intermolecular interaction at the boundary of the polymer with the fibrous matrix during the formation of carbon-fiber composite materials.…”

Some Features of Copoly(Arylene Ether Ether Ketone) Synthesis by Nucleophilic Substitution Reaction

“…At the moment, due to the unique performance characteristics, the issues of synthesis and the properties of poly(arylene ether ether ketone)s (PAEEK) and copoly(arylene ether ether ketone)s (SPAEEK) are being studied [1][2][3][4][5][6].…”
