Segmented polymer nanowires and nanorods by one-step template wetting with a hyperbranched polymer and linear polymer blend

Although segmented polymer nanostructures have been fabricated, it is still a challenge to simplify the fabrication procedures, particularly for the construction of new segmented structures. In this work, a one-step approach is proposed to fabricate hyperbranched polymer (HBP)/linear polymer (LP) segmented nanostructures by wetting the channels of anodized aluminum oxide (AAO) templates with HBP/LP blend melts. The surface properties including wettability and droplet impact behavior of the as-prepared segmented nanostructures can be regulated by tuning the content or the number of terminal hydroxyl groups of HBP.
