摘要：
The properties of composite films based on polyacrylonitrile and detonation nanodiamonds were studied. It was found that the surface properties of the films (roughness and specific free surface energy) do not change when nanodiamonds are added. It was shown by autoradiography technique with tritium-labeled nanodiamonds that the distribution of particles in a film depends on the modification of their surface. Additives of particles and heat treatment affect the mechanical behavior of the films, and the samples become more brittle. Modification of the nanodiamonds with perfluorononanoic acid leads to a decrease in the strength of the films.
