Ultrathin transparent conductive films of polymer-modified multiwalled carbon nanotubes

Article Abstract:

The deposition of multiwalled carbon nanotubes modified by poly(2-vinylpyridine) (CNT-g-P2VP) from aqueous dispersions at low pH is found to be an effective method to prepare homogeneous ultrathin films with a tunable CNTs density. Although the multiwalled CNT films are less conductive and less transparent than the SWNT films, they might be used in touch screens, reflective displays, EMI shielding and static charge dissipation.

Hydrate film growth on the surface of a bas bubble suspended in water

Article Abstract:

The lateral water film growth rate of C[H.sub.4], [C.sub.2][H.sub.4], C[O.sub.2], C[H.sub.4] + [C.sub.2][H.sub.4] and C[H.sub.4] + [C.sub.3][H.sub.8] hydrates in pure water are measured at fixed temperatures by suspending a single gas bubble in water. The results have shown that the thicknesses of mixed-gas hydrate films are thicker than those of pure gases.
