Materials Approach to Dissecting Surface Responses in the Attachment Stages of Biofouling Organisms

Abstract

We have used a suite of ten xerogel coatings to examine the surface response toward the settlement of fouling organisms in laboratory tests and in the field. The coatings are organically modified xerogel surfaces with tunable surface energy, hydrophobicity/hydrophilicity, and charge. Principle component analysis indicated the surface charge and hydrophobicity as expressed in the non-polar component of surface energy were the primary determinants of settlement responses. Quantitative analysis of genetics in settlement preference was begun and will be continued in future work.
