Abstract
Coating is a way of protecting the surface of the materials as glass, metal, clay, wood, and cementitious from pollutant, dust. self-cleaning coating can be achieved by modifying the surface to have super-hydrophobic, super-hydrophilic, and photocatalytic properties. This paper summarizes the recent studies on TiO2 based self-cleaning coating. The scope of this article is in the mechanism and fabrication route of TiO2 based self-cleaning coating, application technique such as spin coating, spray coating dip coating a nd chemical vapour deposition (CVD) and characterization. Self-cleaning coating can be characterized using many methods in order to determine their quality and feasibility. The characterization of the surface applied by self-cleaning coating can be in the form of numerical data and morphological images such as X-ray diffraction (XRD), Scanning Electron Microscope (SEM), Atomic Force Microscopy (AFM), contact angle, hardness, and scratch resistance are also analysed a nd discussed.
