Abstract

The invention aims to provide an independent polymer nanotube, and a preparation method and application thereof. The independent polymer nanotube is prepared by combining an aluminum oxide template method and an ultraviolet irradiation method. The preparation method comprises the following steps: preparing a polymer nanotube film with a porous aluminum oxide template, and treating the polymer nanotube film under an ultraviolet irradiation system to peel the attached polymer nanotube from the polymer film, thereby obtaining the independent polymer nanotube. The invention has the advantages of simple operating process route, low energy consumption and no pollution, and provides a new way for preparing the high-polymer nanotube with dispersive independence.
