" Polymer-multiwall carbon nanotube " nanocoatings on macroporous silicon matrix

Carbon nanotubes are among the most anisotropic materials known and have extremely high values of Young's modulus. The possibilities to enhance the properties of nanostructured surfaces were demonstrated on “polymer-multiwall carbon nanotube” composites and composite nanocoatings on macroporous silicon structures. Influence of sp hybridization bonds on polymer crystallization and strengthening was investigated in composite films of polypropylene and polyamide with carbon multiwall nanotubes. It was established that the effective way to improve the strength properties of “polymer-multiwall carbon nanotube” composites is the composite crystallization and sp C-C tetrahedrons organization between nanotubes supported by γω(CН) and γω(CH2) vibrations in the intrinsic electric field. The effects of blooming, photoluminescence increase and surface bond passivation by nanocoatings of “polymermultiwall carbon nanotube” on macroporous silicon structures were evaluated.
