Abstract
The influence of various structural types of smart dispersion-filled polymer composite materials (DFPCMs) on such shape-memory effect (SME) parameters as the shape fixation and recovery coefficients (Rf and Rr) and SME kinetics characterized by the rate of the initial shape recovery (υr) was studied for the first time, with the polyurethane + modified silicon carbide (SiC) particles as example. The main dependences describing the relationship of the shape fixation and recovery coefficients (Rf and Rr) and of the shape recovery rate (υr) with the generalized parameter Θ, DFPCM structural type, and surface morphology of SiC particles were found. The contribution of the specific surface area of dispersed SiC particles (SBET from 3 to 45 m2 g–1) to the smart properties of the disperse systems was demonstrated for the first time.
期刊介绍：
Russian Journal of Applied Chemistry (Zhurnal prikladnoi khimii) was founded in 1928. It covers all application problems of modern chemistry, including the structure of inorganic and organic compounds, kinetics and mechanisms of chemical reactions, problems of chemical processes and apparatus, borderline problems of chemistry, and applied research.
