Abstract
A sustainable approach is proposed to prepare hollow titanium oxide nanostructures. Pullulan electrospinning is coupled with titanium magnetron sputtering to create organic-inorganic fibers. Through water solubilisation of the pullulan core, hollow titanium oxide nanostructures were obtained. The fibers were embedded in a thermoplastic matrix to form composites in which channels can be created.
