摘要
Inspired by the micro-nano structure on the surface of biological materials or living organisms,micro-nano structure has been widely investigated in the field of functional coatings.Due to its large specific surface area,porosity,and dual-scale structure,it has recently attracted special attention.The typical fabrication processes of micro-nano structured coatings include sol-gel,hydrothermal synthesis,chemical vapor deposition,etc.This paper presents the main features of a recent deposition and synthesis technique,liquid plasma spraying(LPS).LPS is an important technical improvement of atmospheric plasma spraying.Compared with atmospheric plasma spraying,LPS is more suitable for preparing functional coatings with micro-nano structure.Micro-nano structured coatings are mainly classified into hierarchical-structure and binary-structure.The present study reviews the preparation technology,structural characteristics,functional properties,and potential applications of LPS coatings with a micro-nano structure.The micro-nano structured coatings obtained through tailoring the structure will present excellent performances.
