CHITOSAN AND/OR CHITIN COMPOSITE HAVING REINFORCED PHYSICAL PROPERTIES AND USE THEREOF

摘要

Provided are a composite comprising chitosan and/or chitin and a catechol-based compound, an organic reinforcing material composition comprising said composite, a product produced from said organic reinforcing material composition and a method for preparing chitosan and/or chitin composite having increased strength, comprising a step of adding a catechol-based compound to chitosan and/or chitin. The chitosan and/or chitin composite comprising said catechol-based compound has advantages in that the degradation of strength caused by moisture is significantly improved as compared with cases which contain no catechol-based compound, thus maintaining high strength even after wetting and swelling.
