METHODOLOGICAL ASPECTS OF THE PHASE MORPHOLOGY ANALYSIS IN MATERIALS BASED ON SYNTHETIC RESINS MODIFIED BY THERMOPLASTICS (review)
Modifying of synthetic resins with thermoplastics efficiently increases fracture toughness of polymer composite. Structurization in thermoset-thermoplastic blends is accompanied by reaction-induced micro-phase separation with forming of characteristic phase morphology. The current state of electron microscopy researches of phase morphology of thermoset-thermoplastic blends and composite materials on their basis is considered in this work. The following methodological problems of electron microscopy research of phase morphology are considered: information provided by research method, contrasting efficiency of characteristic elements of microstructure, justification of key morphological parameters choice and methods of their measurement.
