“…This type of behavior can be rationalized, for example, by the greater molecular defect structure of atactic PMMA (e.g., the presence of head-to-head links between the monomers) used in our experiments compared to PS. Moreover, this is in agreement with the improvement of mechanical properties of a-PMMA-fullerene composites compared to PS-fullerene composites [12] (3) PTFE with the same friction parameters and geometry. Counterbody: steel face milling cutter.…”

The friction-induced volatile products formation for symmetric and asymmetric polymer friction pairs as revealed by mass spectrometry is discussed. Examples include the symmetric poly(methylmethacrylate)-poly(methylmethacrylate) (PMMA-PMMA) and asymmetric PMMA-PS (polystyrene) friction pairs. In particular, we show that volatile products of polymers formed upon friction may differ from those formed upon thermal decomposition of the polymers or subjected to other modes of fracture (e.g., cleavage of brittle PMMA and PS).

“…Fullerenes and other carbon nanostructures such as nanotubes and graphene sheets can be used as reinforcements of the polymer composites [2][3][4]. According to experimental researches, the incorporation of the fullerene into polymer matrices can significantly enhance their mechanical properties [5][6][7][8][9][10].…”

In this paper, a multiscale method is developed to predict Young's modulus of Fullerene-Reinforced Polymer Nanocomposites (FRPNs). Poly methyl methacrylate (PMMA) is chosen as the polymer matrix while C60 fullerene is considered as the reinforcement. First, molecular dynamics (MD) simulations are conducted to calculate the Young modulus of nanocomposite unit cell with different weight fractions of fullerene. Then, a micromechanics model for a composite with multi-inclusion reinforcements is developed based on the extension of the Mori-Tanaka model and generalized Eshelby's results. Numerical results obtained from the proposed micromechanics model are compared with those calculated from the MD simulations and good agreement is achieved. In addition, we propose an extension for the Halpin-Tsai model to predict Young's modulus of the FRPNs.

“…[36] Recently, he and his colleagues studied the effect of C 60 on the structure and mechanical properties of PE, PMMA, and other vinyl polymers. [37,38] Even more recently he explained the initial decrease in the density of solutions with the dissolving of C 60 and C 70 in the one-ring aromatic solvents. [39] The research results of B. M. Ginzburg are reflected in more than 300 scientific articles, with only 39 referred to earlier.…”
