Abstract

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).

基于内摩擦光谱的环氧低聚物硬化体 "结构-性能 "关系的现象学描述

摘要对环氧低聚物的各种液体固化剂（TETA、PEPA 和 MTHPA）通过自由阻尼扭转振荡方法获得的内摩擦谱和温度频率相关性实验数据进行了理论分析。考虑并采用了主要的现象学模型表示法，以分析局部耗散过程的各种物理机械和物理化学特征，这些过程可能具有不同的内摩擦机制（滞后型、相位型和弛豫型）。

期刊介绍： Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
