Abstract: A base material includes a base layer. The base layer includes a structured surface. The base layer includes a transition metal and a transition metal oxide, and a sum of the transition metal and a transition metal oxide accounts for at least 90 wt. % of the base layer. The transition metal oxide is concentratedly distributed on the structured surface. The base material is flexible in at least one direction, and has a bending angle of not less than 90° when being bent.
