Latest Patents

O'Brien's latest patents focus on the formation of polyhexahydrotriazine (PHT) film layers through a specific heating process. The method involves heating a mixture of a solvent, paraformaldehyde, and a diamine monomer with two primary aromatic amine groups. This process occurs at temperatures ranging from about 20°C to less than 150°C, resulting in a stable polyhemiaminal (PHA) in solution. The PHA can then be cast onto a substrate to form an initial film layer. This layer is subsequently heated to temperatures between 180°C and 280°C, converting it into a PHT film layer. The resulting PHT film layers exhibit Young's moduli ranging from about 8 GPA to about 14 GPA, showcasing their potential for various applications.
