This course provides participants with a fundamental and comprehensive introduction and overview on sol-gel chemistry and sol-gel based coating processes, different coating functions and properties, and coating characterisation techniques. Detailed principles and coating materials design for several specific coatings such as scratch resistant coatings, photocatalytic coating, hydrophobic coating and electrochromic & photochromic coatings will be introduced. Laboratory sessions will provide hands-on experiences on characterisation techniques: contact angle measurement, scratch resistance test, adhesion test, roughness measurement, optical properties measurements, cross-section specimen preparation and microstructure analyses.
