Nanopillar/tube arrays have emerged as encouraging platforms,
possessing
remarkable advantages, including large specific areas and highly aligned
orientations. Despite the progress of nano/microfabrication technologies,
facile and controllable fabrication of conductive polymer nanopillar/tube
arrays remains challenging. In this study, we demonstrate that the
air–liquid interfacial self-assembly can be extended to obtain
three-dimensional nanostructured arrays. A smart and novel method
is proposed for preparing uniform conductive polymer nanopillar/tube
arrays by a template-mediated interfacial synthesis approach. By utilizing
capillary force, precise control processes of the nanostructure and
patterned structure can be easily realized. Furthermore, a transfer
strategy is devised, allowing for scalable fabrication and expansion
of the applicability. Applications, including antibacterial surfaces
and actuators, have been demonstrated. We extend the air–liquid
interfacial synthesis technique as a powerful and universal strategy
for producing ordered nanopillar/tube arrays and show the great potential
of soft nanostructured arrays as advanced platforms in diverse applications.
