Title (EN) CHITOSAN AND/OR CHITIN COMPOSITE HAVING REINFORCED PHYSICAL PROPERTIES AND USE THEREOF
(FR) COMPOSITE DE CHITOSANE ET/OU DE CHITINE AYANT DES PROPRIÉTÉS PHYSIQUES RENFORCÉES ET SON UTILISATION
(KO) 물성이 강화된 키토산 및/또는 키틴 복합체 및 그 용도
Abstract: front page image
(EN)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.
(FR)La présente invention concerne un composite comprenant du chitosane et/ou de la chitine et un composé à base de catéchine, une composition de matériau de renforcement organique comprenant ledit composite, un produit fabriqué à partir de ladite composition de matériau de renforcement organique et un procédé de préparation de composite de chitosane et/ou de chitine ayant une résistance accrue, comprenant une étape consistant à ajouter un composé à base de catéchine au composite de chitosane et/ou de chitine. Le composite de chitosane et/ou de chitine comprenant ledit composé à base de catéchine est avantageux en ce que la dégradation de la résistance causée par l'humidité est considérablement améliorée par rapport aux cas qui ne contiennent pas de composé à base de catéchine, maintenant ainsi une résistance élevée même après mouillage et gonflage.
(KO)키토산 및/또는 키틴 및 카테콜계열 화합물을 포함하는 복합체, 상기 복합체를 포함하는 유기 보강 소재 조성물, 상기 유기 보강 소재 조성물로 제조된 제품, 및 키토산 및/또는 키틴에 카테콜계열 화합물을 첨가하는 단계를 포함하는 강도가 증진된 키토산 및/또는 키틴 복합체의 제조 방법이 제공된다. 상기 카테콜계열의 화합물을 포함하는 키토산 및/또는 키틴 복합체는 카테콜계열 화합물을 포함하지 않는 경우와 비교하여 수분에 의한 강도 저하 문제가 현저하게 개선되어, 습윤 팽윤된 후에도 높은 강도를 유지할 수 있다는 이점을 갖는다.
