文摘

Large-scale pyramid-like micropatterns were prepared via capillarity-driven self-assembly during the evaporationof water from aligned carbon nanotubes (ACNTs) wrapped by a polyelectrolyte, poly (sodium 4-styrenesulfonate) (PSS). PSS wrapping results in providing negative charges on every tube, which makes it possibleto balance the capillary force and to form uniformed pyramid-like architecture. By using such regular three-dimensional CNT patterns as an idea candidate for the framework/template, two complex architecturesconsisting of ZnO nanorods and CNT patterns were successfully fabricated, which show revisable surfacewettability properties.
