Abstract: Despite numerous studies and measures were used, corrosion and deposition of fouling on the heat transfer surfaces are still the major problems in design and operation of industrial heat exchangers. Surface of heat exchangers with enhanced corrosion resistance, antifouling and high thermal conductivity coatings is the most important approach to solve these problems. This article described the development of multifunctional coatings applied on the surface of heat exchangers. The main advantages and disadvantges of these systems were presented along with a brief introduction of their scientific basis. Finally, combined with the development of nano-technology, the further development of multi-functional coatings for surface of heat exchangers and its prospects were proposed.
