Abstract

In this paper,the attachment processes and mechanisms of several typicalmarine fouling organisms were reviewed. Among them,bacteria attached to surfaces through intermolecular forces,diatoms attached by secreting extracellular polymers,barnacles secrete barnacle gum that allowed them to attach firmly to solid surfaces,mussels attached mainly by their powerful foot filaments,and the attachment process of seaweeds was mainly the selectivelanding and development of their spores. The attachment of marine fouling organisms usuallyoccured on structural surfaces,and the attachment behavior of organisms could be significantly influenced by the surface properties. The coating surface morphology affected the effectivecontact area between organisms and the surface;the effect of surface energy depended mainlyon the coating type,both superhydrophobicity and superhydrophilicity were beneficial for fouling resistance;and the lower elastic modulus and the thicker coating thickness werefavorable for the dislodgement of adhering organisms from the surface.
