077 Carbon nanotubes filled composite materials |
Authors: | Yu.Sementsov, G. Prikhod’ko, N. Kartel’, M. Tsebrenko, T.Aleksyeyeva, N. Ulyanchych. | |
Summary: | It was shown that insertion of carbon nanotubes (CNT) in different matrixes, such as polymers, hydroxyapatite (HAP), elastomers and liquid Selenium, leads to significant changes of their parameters. The influence of filler appears on strength characteristics of obtained composite materials. Such changes were due to CNT net-working in initial matrix. Also it was shown that not only volume characteristics of filled composites but surface properties are changing and this explains the better biocompatibility of nanocomposites, which is observed in vivo experiments. | |

077 Rheological Properties of Molten Mixtures of Polypropylene Copolyamide/Carbon Nanotubes Mixture Melts |
Authors: | Resanova N.M., Kartel M.T., Sementsov Yu.I., Prikhod’ko G.P., Melnik I.A., Tsebrenko M.V. | |
Summary: | Influence of carbon nanotubes (CNT) admixture on law of a current of polypropylene/sopoliamid melts is investigated. The increase of viscidity and elasticity, diminishing of sizes of longitudinal deformation of three-component compositions melting, is set. These effects are explained by the change of processes of gelation under influence of nanoscaleaddition. It is shown that the sys-tems with nanosized fillerare processed on standardequipment with the use of technological parameters and, which are used for initial mixture. | |

077 POLYPROPYLENE FIBERS FILLED WITH CARBON NANOTUBES: MECHANICAL PROPERTIES AND BIOCOMPATIBILITY |
Authors: | Yu.I. Sementsov, G.P. Prikhod’ko, N.T. Kartel, T.A. Aleksyeyeva, M.V. Tsebrenko | |
Summary: | There have been investigated the process of generating polypropylene fibers filled with carbon nanotubes, their mechanical properties and biocompatibility. It has been found that the increase in the content of carbon nanotubes in the fibers of PP-CNTs increases the viscosity of the melt and reduces the elasticity. Biocompatibility testing of the fiber of PP-BHT showed a nonmonotonic effect of the content of tubes for compatibility of the polymer matrix with living tissues. It has been revealed that the composite with CNT concentration of 1.0 wt. % causes the least disturbance of the living organism and the tissue reaction to the implant has a local aseptic character. | |

077 Carbon Nanotubes Deagglomeration in Aqueous Solutions |
Authors: | E. O. Kovalska, Yu. I. Sementsov | |
Summary: | Deagglomeration of the carbon nanotube bundles were performed in an aqueous solutions of different chemical composition using ultrasound, cavitation, and rotating homogenizing treatment. Found that the degree of dispersion on the cavitation principle strongly depends on the concentration of CNTs in the water. Using organic compounds (C6H12O6) increases the efficiency of the dispersion. Ultrasound effect is manifested in the destruction of agglomerates CNTs and size. Processing in a universal homogenizer of water-soluble polymer and ionic surfactant system/CNTs had allowed obtaining highly stable solution with a particle size from 150 to 400 nm. The particle size depends on the concentration of components in the system. Utilizing the CNT/water-soluble polymer/ionic surfactant mixture coupled with homogenizer machine shows the best results in terms of the solution stability, particles size, and their distribution. | |
