CARBONACEOUS MESOPHASE

Atomistic Monte Carlo Simulations on the Formation of Carbonaceous Mesophase in Large Ensembles of Polyaromatic Hydrocarbons

Mesophase behaviour of polyhedral particles.

Translational and orientational excluded-volume fields encoded in particles with anisotropic shapes can lead to purely entropy-driven assembly of morphologies with specific order and symmetry. To elucidate this complex correlation, we carried out detailed Monte Carlo simulations of six convex space-filling polyhedrons, namely, truncated octahedrons, rhombic dodecahedrons, hexagonal prisms, cube...

Mesophase separation in polyelectrolyte-mixed micelle coacervates.

Mesophase separation has been identified in a polycation/anionic-nonionic mixed micelle system formed by the coacervation of poly(diallyldimethylammoniumchloride)/sodium dodecylsulfate-Triton X-100 in 0.40 M NaCl. The resultant dense, optically clear fluid was studied by turbidity, dynamic light scattering (DLS), and rheology. The presence of two diffusion modes in DLS points to microscopic het...

Preparation Of Mesophase From Anthracene Oil

The transformation of anthracene oil into pitch is a feasible procedure for obtaining pitches with binder and impregnating characteristics. Moreover, their high aromaticity, total absence of solid particles and good fluidity make anthracene oil-based pitches interesting precursors for graphitizable carbon materials (e.g., carbon fibres, synthetic graphites). To prepare this kind of material the...
