| titleOfInvention | Biomimetic polybenzoxazine of mussel containing catechol group and its synthesis and application |
| abstract | The invention relates to mussel biomimetic polybenzoxazine containing catechol group and its synthesis and application. The phenolic compound, amine compound, formaldehyde compound and solvent containing at least two ortho phenolic hydroxyl groups are mixed, stirred evenly, The reaction is carried out at a temperature of 80-95 °C, and the solvent is removed after the reaction is completed, and the product is washed and vacuum-dried to obtain a mussel biomimetic benzoxazine monomer; the mussel biomimetic benzoxazine monomer is thermally cured at 180-200 °C After 8 to 16 hours, a mussel biomimetic polybenzoxazine containing a catechol group is obtained. The existence of the catechol structure in the present invention can improve the bonding performance of the polybenzoxazine by 53%, and the bonding strength can reach 2.6MPa. The mussel biomimetic benzoxazine monomer has an autocatalytic ring-opening effect, which can reduce the ring-opening polymerization temperature by 80 °C, overcoming the limitation of the high curing temperature of benzoxazine. |
