“…There have been a number of studies investigating the deposition of fullerenes onto polymer surfaces. 10 However, these studies have generally been focused on immobilizing the C 60 onto the surfaces, i.e., covalently bonding the fullerene to the polymer. For example, Birgulin et al 10a investigated [60]fullerene solid films deposited on polyacrylonitrile substrates by vacuum sublimation.…”

Classical Molecular Dynamics Study of [60]Fullerene Interactions with Silica and Polyester Surfaces

2006

This study examines the interaction of neutral and charged fullerenes with model silica and polyester surfaces. Molecular dynamics simulations at 298 K indicate that van der Waals forces are sufficiently strong in most cases to cause physisorption of the neutral fullerene particle onto the surfaces. The fullerenes are unable to penetrate the rigid silica surface but are generally able to at least partially infiltrate the flexible polymer surface by opening surface cavities. The introduction of charge to the fullerene generally leads to an increase in both the separation distance and Work of Separation with silica. However, the charged fullerenes generally exhibit significantly closer and stronger interactions with polyester films, with a distinct tendency to absorb into the "bulk" of the polymer. The separation distance and Work of Separation of C60 with each of the surfaces also depend greatly on the sign, magnitude, and localization of the charge on the particle. Cross-linking of the polyester can improve resistance to the neutral fullerene. Functionalization of the polyester surface (F and OH substituents) has been shown to prevent the C60 from approaching as close to the polyester surface. Fluorination leads to improved resistance to positively charged fullerenes, compared to the unmodified polyester. However, hydroxylation generally enables greater adhesion of charged fullerenes to the surface due to H-bonding and electrostatic attraction.

“…''Owing to ability of C 60 for selective destruction of some polymers in the conditions of the joint solution fullerene can be present as separative multiadducts -products of interaction with polymer and also with solvent''. 35,45,51,52 Attention is drawn to the relatively large number of publications devoted to studying the complexation of commercial nontoxic water-soluble polymers PVP, PEO, poly(ethylene glycol) (PEG) is large. This tendency is related to the high biological activity of fullerene and challenging problems of how to transfer this water-insoluble carbon modification (the solubility of fullerene C 60 in water can be as low as 1.3 Â 10 À11 mg ml À1 53 ) to a soluble state for its further use in medicine and biology.…”

The Role of Reduced Graphene Oxide in the Suspension Polymerization of Styrene and Its Effect on the Morphology and Thermal Properties of the Polystyrene/rGO Nanocomposites

et al. 2020

View full text Add to dashboard Cite

Reduced graphene oxide (rGO) was used to obtain Polystyrene (PS)/rGO nanocomposites via in-situ suspension polymerization. The main goal of the article was to determine how rGO influences the morphology and thermal properties of PS beads. The obtained samples were studied by means of a scanning electron microscope (SEM), and calorimetric and thermogravimetric analysis (DCS, TGA). It was proven that the addition of rGO, due to the presence of polar functional groups, causes significant changes in bead sizes and size distribution, and in their morphology (on the surface and in cross-section). The increasing amount of rGO in the polymer matrix increased the size of beads from 0.36 to 3.17 mm for pure PS and PS with 0.2 wt% rGO content, respectively. PS/rGO nanocomposites are characterized by distinctly improved thermostability, which is primarily expressed in the increase in their decomposition temperature. For a sample containing 0.3 wt% rGO, the difference is more than 12 °C in comparison to pure PS beads.
