A coating for an article may be made by applying a powder of a polyhemiaminal (PHA) polymer material to the article in a particulate form and then converting the PHA polymer material to a polyhexahydrotriazine (PHT) polymer material and fusing the particles into a monolithic coating by applying heat to the particles. The method generally includes forming a dilute reaction mixture comprising a formaldehyde reactant, a solvent, a primary aromatic diamine, and heating the reaction mixture to a temperature of between about 20° C. and about 120° C. for a short time to form a polymer. A particulate solid is precipitated by adding an excess volume of a non-solvent to the mixture. The powder may be applied to an article and then heated to fuse the powder into a coating and convert the PHA to PHT.

Display modules typically incorporate a transparent hard material such as glass on the outside of the module in order to better protect the display stack from scratches, dents, and other mechanical deformations. However, as displays move to novel form factors such as bendable, foldable, and reliable display modules, these transparent hard materials (e.g., glass) may not be used due to their limited flexibility. Therefore, it is desirable that replacement materials be sufficiently flexible while maintaining the desirable optical (e.g., >90% transmission and low yellow index) and mechanical properties (e.g., pencil hardness >H) that comparable glass hard materials offer.
