Fabrications and Applications of ZnO Nanomaterials in Flexible Functional Devices-A Review

The present review focuses on the preparations, properties, and applications of zinc oxide (ZnO) nanomaterials in flexible functional devices. An overview is given on several methods for the growth of ZnO nanomaterials, including sputtering, sol-gel method, atomic layer deposition, all-inkjet-printing approach, electrochemical deposition, hydrothermal method. The broad applications of ZnO nanomaterials in solar cell, supercapacitors, flexible piezoelectric nanogenerators, ultraviolet photodetectors, photodiodes, porous three-dimensional (3-D) ceramics, functional surface coating, and sensors are also discussed.
