Polyethylene microtubes are obtained through in situ polymerization catalyzed by Cr active sites anchored on the surface of silica microfibers, followed by removal of the silica core by selective chemical etching (see figure). No cocatalysts or solvents are required for this inverse‐templating method, and the obtained microtubes are potentially applicable in several fields of nanotechnology.
