摘　　要：海洋污损生物的粘附已经成为人类开发海洋的一大障碍,研究海洋污损生物的粘附机制对航海运输具有重要意义。本文综述了包括双壳类,多毛虫,菌类等在内的三种海洋污损生物的表面粘附机制,三者释放的粘附蛋白具有高强度、高韧性和防水性的特点,对基底具有极强的粘附能力。这种功能主要源自核心的3,4-二羟基苯丙氨酸(DOPA)介导交联和其与基底之间的相互作用,受其启发,可以设计开发多种基于DOPA的抗粘附材料、生物医用材料及防水粘结剂等,均有着广泛的应用。Biofouling has become such a tremendous hindrance to ocean development, that to investigate corresponding adhesion mechanism of the fouling organism will have obvious promotion to the antifouling and marine transport industry. Herein, we introduce adhesion mechanisms for marine mussels, polychaetes and bacteria, respectively. The above three are believed to release some specific adhesive proteins with strong intensity, high tenacity, moisture resistance and strong adhesive ability to various substrates. These functions mainly originate from the interaction between the substrates and the critical 3, 4-dihydroxyphenylalanine （DOPA）. Inspired from this mechanism, a series of DOPA-based compounds have been developed and found a lot of applications in anti-adhesive materials, biomedical materials and waterproof adhesives, etc. Recent progress in this area is also summarized in this review.
