Towards eco-friendly marine antifouling biocides-Nature inspired tetrasubstituted 2,5-diketopiperazines

Thomas M. Grant et al.

Summary: Marine biofouling poses significant economic and environmental challenges to maritime industries, prompting the search for eco-friendly alternatives. Recent studies have shown that amphiphilic micropeptides exhibit excellent antifouling activity and biodegradability.

In situ generation of amphiphilic coatings based on a self-catalytic zwitterionic precursor and their antifouling performance

Donghui Wang et al.

Summary: The study developed a new zwitterionic precursor for easy fabrication of amphiphilic antifouling coatings, which effectively mitigated microfouling and demonstrated excellent resistance to mussel fouling. The precursor could hydrolyze in-situ into zwitterionic groups during the curing process, improving compatibility with PDMS and leading to a relatively homogeneous and smooth surface after prolonged submersion.

Managing Biofouling on Submerged Static Artificial Structures in the Marine Environment - Assessment of Current and Emerging Approaches

Grant Hopkins et al.

Summary: The number of submerged static artificial structures (SSAS) in the marine environment is increasing, leading to biofouling accumulation and potential impacts. Current management methods are mainly reactive and mechanical, but there is a need for more innovative technologies for proactive and preventive approaches. Further research and testing are essential to ensure efficacy and feasibility at operational scales.

Biomimetic surface coatings for marine antifouling: Natural antifoulants, synthetic polymers and surface microtopography

Liren Chen et al.

Summary: This study focuses on the research frontier of marine antifouling coatings from a bionic perspective. It demonstrates three main bioinspired strategies: natural antifoulants, bioinspired polymeric antifouling coatings, and biomimetic surface microtopographies. The fabrication methods, antifouling performances, advantages, and drawbacks of these coatings are presented along with an interpretation of the antifouling mechanisms.
