Figure 2From: Controlling the morphological, structural, and optical properties of one-dimensional PCDTBT nanotubes by template wettingSchematic illustrations on the formation of PCDTBT nanotubes. Formation of PCDTBT nanotubes due to (a) Capillary and gravitational force of PCDTBT solution inside nanopores and (b) wetting and complete filling of the nanopores. (c) Formation of convex meniscuses and (d) PCDTBT nanotubes of broken meniscuses.Back to article page
