METHODS OF PREPARING POLYHEMIAMINALS AND POLYHEXAHYDROTRIAZINES |
摘要 |
Polyhexahydrotriazine (PHT) film layers are formed by a process comprising heating a first mixture comprising i) a solvent, ii) paraformaldehyde, and iii) a diamine monomer comprising two primary aromatic amine groups at a temperature of about 20°C to less than 150 °C. This heating step forms a stable polyhemiaminal (PHA) in solution, which can be cast on a surface of a substrate, thereby forming an initial film layer comprising the PHA. The initial film layer is heated at a temperature of 180°C to about 280°C, thereby converting the PHA film layer to a PHT film layer. Young's moduli of about 8 GPA to about 14 GPA have been observed for the PHT film layers. |
