Phenomenological Description of the “Structure–Property” Relation for Epoxy Oligomer Hardeners on the Basis of Internal Friction Spectra
A theoretical analysis has been performed for experimental data on internal friction spectra and temperature–frequency dependences obtained by the method of free damped torsional oscillations for diverse liquid hardeners (TETA, PEPA, and MTHPA) of epoxy oligomers. The main phenomenological model representations have been considered and employed to analyze various physicomechanical and physicochemical characteristics of local dissipative processes, which may have different mechanisms of internal friction (hysteresis-, phase-, and relaxation-type).
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
