HEAT RESISTANCE BIO-ADHESIVES

摘要

An adhesive material produced by contacting a catechol with an amine may be stable under heated conditions and produce minimal outgassing under vacuum. The catechol may be an un-substituted catechol or a substituted catechol, such as hydroxychavicol. In some examples, the catechol may be derived from botanical sources. The amine may be a diamine, such as phenylene diamine. The adhesive polymer may form dendritic structures or macrocyclic structures. A joined article may be fabricated from two materials by applying the adhesive to a prepared surface of at least one of the materials, and the two materials may be placed together with the adhesive between them. The adhesive in the joined article may be cured at ambient temperature or under heating conditions.

主权项

1. A method for making an adhesive, the method comprising:
contacting at least one catechol with at least one amine to form a first mixture; adding at least one solvent to the first mixture to form a second mixture; and subjecting the second mixture to at least one reaction condition thereby forming the adhesive.
