A method is provided for manufacturing a polymeric film with thermal management capabilities. The method comprises mixing at least three compounds, wherein a first compound comprises a polymeric phase change material, a second compound comprises an additive, and a third compound comprises a molecule that, in its liquid form, acts as a solvent of the first and second compounds, and which is curable into a solid form as a polymer. Then, the method comprises applying a mixture of the first, second, and third compounds in a liquid form to a substrate, and curing the mixture into a solid state.
