The structure of polymer nanocomposites containing CuS clusters is studied by atom force (AFM), scanning (SEM), and transmission (TEM) electron microscopy, and by narrow-angle X-ray scattering (SAXS). The results point to the existence of spherical nanoparticles of 3–50 nm in diameter and larger agglomerates of sizes 1–5 μm in the studied nanocomposites (NCs). The morphology of NCs depends on the conditions of synthesis.

It is shown that a continuous polymer coating with a bilayer thickness of about 3.5 μm is formed on the pericardum surface. It is also found that the wettability of modified pericardum surface appreciably increases.

Polycaproamide composites are synthesized by the anionic activated bulk polymerization of ɛ-caprolactam in the presence of 0.1–5.0 wt % of multiwalled carbon nanotubes and using low-molecularmass monofunctional ( N -acetyl-ɛ-caprolactam) and macromolecular polyfunctional (aromatic polyimides) activating agents. The effect of nanotubes on the polymerization of ɛ-caprolactam is studied, and this effect is shown to become more pronounced as the concentration of nanotubes is increased. The effect of nanotubes on the microstructure, phase composition, water sorption, thermophysical, mechanical, and friction characteristics of poly(caproamide) is analyzed.

19Graft Copolymers of Polycaproamide with Polyimide Based on Fluorene Dianiline and 3,3′,4,4′-Tetracarboxydiphenyloxide: Microstructure and Properties

T. V. Volkova,O. N. Pashkova,M. N. Il’ina,E. M. Belavtseva,Ya. S. Vygodskii

It is established that graft copolymers of polycaproamide with 3–5 wt % of polyimide exhibit a rubber-like elasticity region above the polycaproamide melting temperature. Polycaproamide modification with polyimide increases the polymer thermal resistance, glass-transition temperature, and impact strength. Scanning electron microscopy revealed that the supramolecular organization of polycaproamide is similar to that of its copolymers with polyimide but differs in the spherulite size.
