BIO-ADHESIVE FOR LIVING ORGANISM COMPRISING POLY L-3,4-DIHYDROXYPHENYLALANINE AND CYANOACRYLATE, AND PREPARATION METHOD THEREOF

摘要

PURPOSE: A bio-adhesive is provided to form a coating film with strong adhesion and improved physical properties, to remarkably reduce side-effect like inflammation, etc, and to have excellent profitability. CONSTITUTION: A bio-adhesive comprises poly L-3, 4-dihydroxyphenylalanine having a repeating unit in chemical formula 1, and cyano acrylate. In chemical formula 1, A is a bond or -(CH2)l-B-(CH2)m-, B is CH2 or O, l and m is respectively an integer from 1-9, the sum of l and m is 2-10, and a molecular weight of the poly L-3, 4-dihydroxyphenylalanine is 500-5,000,000. The A is a bond, C1-10 alkylene, or -(CH2)-O-(CH2)-. The A is a bond, ethylene, or -(CH2)-O-(CH2)-
