High voltage insulation and dielectric phenomena

Honeycomb-like aligned carbon nanotube films were grown by pyrolysis of iron phthalocyanine. The patterned structure was characterized by a scanning electron micrograph (SEM) and an atomic force micrograph (AFM). Wettability studies revealed the film surface showed a super-hydrophobic property with much higher contact angle (163.4 ± 1.4°) and lower sliding angle (less than 5°)a water droplet moved easily on the surface. In contrast to a densely packed aligned carbon nanotube, the sliding feature was strongly affected by microstructure of surface.
