Patterning is of paramount importance in many areas of modern science and technology. As a valuable part in miniaturized devices, large-scale aligned CNTs with serial port configuration is highly desirable. Here, we reported that the synthesis of a pair of patterned carbon nanotubes with the shape of serial port by CVD starting from different breath figure templates, cross-linked polymer matrix and ferrous inorganic micropatterns. The growth mechanism of the isolated CNT bundles is attributed to the selectively interfacial aggregation of the ferrocene to the walls of the cavities, a so-called Pickering-emulsion effect, whereas the honeycomblike skeleton of the dense CNT arrays develop from the catalytically functionalized hexagonal edges. This synthesis strategy exemplifies a new possibility for making use of CNTs to fabricate functional carbons with unique geometry or specific properties in a controllable way. We expect that the methodology can be also applied onto the fabrication of patterned graphene.
