We report the preparation of a novel type of composites films by chemical solution deposition. It consists of an epitaxial oxide on a single-crystal template inside which an oxide fiber network is dispersed. Electrospinning is used for the deposition of the fiber network, whereas the continuous epitaxial phase is spin-coated. Homogeneous coating is observed between the liquid precursor of the continuous oxide and the fibers and remarkably, epitaxial (001) growth of the YBa2Cu3O7-x is not affected by the presence of the fiber network because both oxides do not react to each other. Topological continuity of the continuous phase is probed by electrical conductivity measurements, rendering nearly the same values reported for fiber-free films. Mechanical properties are determined by nanoindentation at low penetration depths to avoid the effect of the single crystal beneath the composite. Enhanced mechanical properties are found (hardness, Young's modulus, elastic recovery and wear resistance). A thin film of c-axis-oriented epitaxial YBa2Cu3O7-x with embedded electrospun fiber network of BaZrO3 was prepared by chemical solution deposition. Mechanical properties were analyzed in these composite films by nanoindentation, showing an enhancement of hardness, Young's modulus, elastic recovery and wear resistance with respect to the BaZrO3-free films.
