“…More recently, Gao et al 77 investigated poly(n-alkyl methacrylates) end-capped with 2-perfluorooctyl methacrylates (F-MA), exhibiting ordered structures of the fluorinated-chains which results in different CF 3 /CF 2 ratios at the top-surface (Fig. 7b).…”

Non-toxic, non-biocide-release antifouling coatings based on molecular structure design for marine applications

Marine biofouling generally refers to the undesirable accumulation of biological organisms on surfaces in contact with seawater. This natural phenomenon represents a major economic concern for marine industries, e.g. for ships and vessels, oil and wind-turbine sea-platforms, pipelines, water valves and filters, as it limits the performance of devices, materials and underwater structures and increases the costs related to transport delays, hull maintenance and repair, cleaning and desalination units, corrosion and structure break-down. In the last few decades, many efforts have been spent into developing efficient antifouling (AF) surfaces (coatings) combining advances in materials science and recent knowledge of marine chemistry and biology. However, the extensive use of toxic and harmful compounds in the formulations raised increasing health and environmental concerns leading to stricter regulations which pushed marine industries to search for new AF strategies. This review presents the recent research progress made in green strategies for AF coatings using non-toxic, non-biocide-release based principles for marine applications. The two main approaches, detachment of biofoulants or preventing biofoulants attachment, are reviewed in detail and new promising routes based on amphiphilic, (super)hydrophilic, and topographic (structured) surfaces are highlighted. The chemical and physical aspects of the AF mechanisms behind the AF strategies reviewed are emphasized, with special attention to the early stages of biofoulant adhesion, keeping the focus on the materials' molecular structure and properties which allow obtaining the final desired antifouling behaviour.

“…Increasing the length of the fluorinated side chains decreased the surface energy and improved resistance to the bacteria adhesion. In another study, copolymers prepared from n -alkyl methacrylate with different lengths and 2-perfluorooctylethyl methacrylate decreased the adsorption of proteins, such as fibrinogen, linearly with increasing CF 3 /CF 2 ratio [88]. At a CF 3 /CF 2 ratio of 0.26, there was no fibrinogen adhesion on the surface observed.…”

Membranes with Surface-Enhanced Antifouling Properties for Water Purification

et al. 2017

Membrane technology has emerged as an attractive approach for water purification, while mitigation of fouling is key to lower membrane operating costs. This article reviews various materials with antifouling properties that can be coated or grafted onto the membrane surface to improve the antifouling properties of the membranes and thus, retain high water permeance. These materials can be separated into three categories, hydrophilic materials, such as poly(ethylene glycol), polydopamine and zwitterions, hydrophobic materials, such as fluoropolymers, and amphiphilic materials. The states of water in these materials and the mechanisms for the antifouling properties are discussed. The corresponding approaches to coat or graft these materials on the membrane surface are reviewed, and the materials with promising performance are highlighted.

“…41 For example, some of the uorinated polymers with very low surface energy might not have an effective biofouling property if the uorinated chains are restructured by contact with polar liquids including water, [40][41][42] because the reconstructed chains can result in small water CA and large CAH. 41,43,44 We could expect to attribute the difference of CAH values between PHCPMF# and C-PHCPMF# lms to the difference between cross-linked structures; the cross-linking structure that originates from unsaturated long chains in the cardanol moiety increases bacterial adhesion resistance by reducing CAH, as well as the stability for coating applications. It is also well known that cross-linked chains have less chain mobility than linear ones; then, the restructuring by contact with polar solvent can be minimized, and the low surface energy property can be maintained.…”
