A coating composition includes alkaline mineral particles including an oxide of an alkaline earth metal and an amine-containing polymer. The amine-containing polymer is adsorbed on the alkaline mineral particles. Forming a coating composition includes at least partially coating alkaline mineral particles with an amine-containing polymer and dispersing the alkaline mineral particles in a liquid to yield the coating composition. The alkaline mineral particles include an oxide of an alkaline earth metal.

Methods of depositing thermally conductive polymeric films are described. Each of the methods include flowing a first precursor over a substrate; removing a first precursor effluent comprising the first precursor; flowing a second precursor over the substrate to react with the first precursor to form the polymeric film on the substrate; and removing a second precursor effluent comprising the second precursor. The methods may include performing a metal deposition process. The methods may include performing a post-treatment process, such as a heat treatment process.
