Results from Antifouling Studies

The fouling resistance of epoxy and siliconized epoxy coatings was studied by antifouling studies (Table 3.13). 

The specimens were hung vertically using nylon ropes with proper support in a protected area for 300 days. The barnacles, along with other organisms, which settled on the 

From the study it can be concluded that the silicone/ phosphorus modified epoxy coatings prevent the adherence and settUng of marine organisms on steel structures and improve their corrosion resistance. These coatings are determined to have extensive appHcation in the marine industry for improving the longevity of marine structures when compared with other conventioncd coating systems that are currently in use.

These types of switchable electrode surfaces have been used to selectively pattern two different cell populations onto a surface [151] and additionally these surfaces can selectively release different cells at different applied potentials [152]. However, it is important to recognize that electrochemically switching a surface from inactive to conjugation and active to conjugation has been well explored with nitro-terminated aryl diazonium salts. In such studies, the application where very anodic potential resulted in a six-electron reduction to an amine [139], to which proteins could be attached [153-155]. The key difference is that the interaction of the biological medium with the surface is controlled by the presence of the antifouling layer. In many ways these electrode surfaces developed by Mrksich and coworkers [150-152, 156] are very similar to the antifouling surfaces with molecular wires discussed in Section 1.4.2 [131, 132, 138, 142]. In both cases the electrode is...
