Abstract

Amorphous TiO₂ synthesized via Ti anodization is partially crystallized and displays strong microwave absorption ability. The property comes from the interfacial electric field formed at the boundary of crystalline–amorphous phases. This study grants anodic TiO₂ a new potential application for absorbing electromagnetic energy.
