“…Clearly the presence of the ligand in PCBM onto the fullerene cage introduces a strong interaction with the phenyl groups, rather than the polymer backbone. These results also support recent observations, which showed that despite PCBM possessing lower thermal and thermo‐oxidative stability than C 60 , composites of polystyrene with PCBM have higher thermal and thermo‐oxidative stabilities than the corresponding composites with C 60 . This apparent contradiction has been attributed to a higher miscibility limit of PCBM in polystyrene compared to that of C 60 .…”

ABSTRACT:The phase behavior of [6,6]-phenyl C 61 -butyric acid methyl ester (PCBM) blends with amorphous polymers with different degrees of aromaticity has been investigated by differential scanning calorimetry (DSC) and small-angle neutron scattering (SANS). The polymers investigated are the homologous series of polystyrene (PS), poly(2-vinyl-naphthalene) (P2VN), and poly(9-vinyl-phenanthrene) (P9VPh). The DSC results show that the miscibility of PCBM in these polymers increases nonlinearly from 16.5 wt % in PS, 57.0 wt % in P2VN, and 74.9 wt % in P9VPh. The SANS results show that at all concentrations of PCBM, the blends are composed of two mixed phases. Analysis shows that the phase dimensions remain largely independent of PCBM content, but there is a strong dependence of the PCBM concentration difference in the two phases with increasing PCBM content.

“…However, in the case of small nanoparticles dispersed in polymer melts 27,79,102,103 and solutions 104,105 , the validity of Equation 4 is questionable as observed by experiments 66 and theory 69,106 . The nanoparticle diffusivities of the simulated nanocomposite systems are calculated from the mean square displacement measurements given by:…”

Nanoparticle and polymer dynamics in nanocomposites containing spherical nanoparticles were investigated by means of molecular dynamics simulations. We show that the polymer diffusivity decreases with nanoparticle loading due to an increase of the interfacial area created by nanoparticles, in the polymer matrix. We show that small sized nanoparticles can diffuse much faster than that predicted from the Stokes-Einstein relation in the dilute regime. We show that the nanoparticle diffusivity decreases at higher nanoparticle loading due to nanoparticle -polymer interface. Increase of the nanoparticle radius slows the nanoparticle diffusion.

“…Except for C 60 , the impact of its derivatives on the thermal properties of polymers has also been investigated. Paulo et al . systematically studied the effect of C 60 and 6,6‐phenyl‐C61‐butyric acid methyl ester [PCBM, as shown in Scheme (a)] on the thermal stability of PE, PMMA, and PS.…”

At present, the application of fullerene in polymer materials has become an attractive issue. Fullerene can enhance the thermal and flame-retardant properties of polymers due to its high capacity to trap free radicals. Fullerene also has good synergistic effect with inorganic metal flame retardant, intumescent flame retardant, brominated flame retardant (BFR), clay, carbon nanotubes, graphene oxide, and so on. In this review, the impact and mechanism of fullerene and its derivatives on the thermal and flame-retardant properties of polymeric materials are discussed. And the prospect of fullerene in flame-retardant polymer composites is also briefly introduced by analyzing the research progress in the recent years. Scheme 8.
