Abstract The objective of this research is to develop a composite polymer coating with increased thermal conductivity and corrosion resistance for protecting structural materials in heat exchange apparatuses. Chemically pure compounds such as graphene, boron nitride, tyrosine, sodium hydroxide, zinc pyrophosphate, ethyl acetate, and epoxy resin with the addition of secondary polypropylene were utilized as raw materials. The obtained coatings were evaluated using an emission scanning microscope equipped with an energy‐dispersive spectroscopy (EDS) detector. Electrochemical activity was measured using standard equipment within a frequency range of 0.1–0.01 Hz. Thermal conductivity and corrosion resistance were measured at 0.24 W/m K and 9.70 Ω/cm 2 when using only epoxy resin with the addition of secondary polypropylene. When employing a composite consisting of epoxy resin with the addition of secondary polypropylene, boron nitride, graphene, tyrosine, and zinc pyrophosphate, the thermal conductivity and corrosion resistance values were 1.65 W/m K and 11.10 Ω/cm 2 , respectively. Polymer coatings containing 30% composite demonstrated the highest thermal conductivity (1.65 W/m K) and corrosion resistance (11.20 Ω/cm 2 ). The research findings can be utilized to create polymer coatings with enhanced thermal conductivity and corrosion resistance values. This polymer coatings could serve as structural materials for heat exchange devices. Highlights Corrosion resistance increase with complexing of composite coating. Thermal conductivity increase with complexing of composite coating. Use of epoxy resin with secondary polypropylene make thermal conductivity value.
