Effect of C60 fullerene additives on the structure and mechanical properties of thin organic glass films

Nanocomposites of Polyoxymethylene

“…Th e energy wear rate I V of composite material became two times lower than that of pure POM and maintained constant during the measurement. Th e highly noticeable enhancement of the antiwear properties of POM due to the introduction of 1 wt% of FS was explained by a model of the healing of microcracks on fullerenes [83]. A comparison of the tribological characteristics of the POM modifi ed by 1 wt% of FS and two other known materials for water lubricated friction units-polytetrafl uoroethylene and FUT carbon plastic whose matrix is based on phenolformaldehyde resins-showed that POMbased nanocomposite was not inferior to FUT in antifriction properties and even exceeded it somewhat under heavy contact pressures.…”

Polymeric nanocomposites containing non-covalently bonded fullerene C60: properties and applications

“…Mechanical properties of the films, cast from the mixture of PMMA and C 60 (1-10 wt%) in toluene were studied. 61 The curves of uniaxial deformation of the films (s ud -3 ud ) are given in Fig. 2.…”

“…The formation of the covalent bonds between fullerene and macroradicals was proved by the method of thermodesorption mass-spectroscopy. 61 Polyethylene (PE) is the most widespread thermoplast. In spite of the simplicity of the chemical structure, this semicrystalline polymer reveals complex morphology with different hierarchical levels.…”

CLUSTERIZATION OF FULLERENE C70 MOLECULES IN SOLUTIONS AND ITS INFLUENCE TO OPTICAL AND NONLINEAR OPTICAL PROPERTIES OF SOLUTIONS

“…It has been shown that C 60 and C 70 fullerenes in various solvents reveal unusual physical properties like: (i) modulation of absorption and emission spectra arising from slight changes in a solvent composition and a concentration of fullerene in solution; [10][11][12] (ii) nonlinear change of optical susceptibility ð3Þ ð!Þ from concentration; 13 (iii) the nonmonotonic change in the optical density of the solutions as a function of fullerene concentration, 14 etc. The origin of the nonlinear optical properties of fullerenes in solutions is mainly related with the tendency of fullerene molecules and their derivatives to form aggregates (clusters) in solvents.…”
