Biofouling protection for marine environmental sensors

Biofouling protection for marine environmental sensors

These days, many marine autonomous environment monitoring networks are set up in the world. These systems take advantage of existing superstructures such as offshore platforms, lightships, piers, breakwaters or are placed on specially designed buoys or underwater oceanographic structures. These systems commonly use various sensors to measure parameters such as dissolved oxygen, turbidity, condu...

Marine biofouling: a sticky problem.

Organisms that colonise underwater surfaces, such as barnacle larvae and spores of algae, use a diverse array of biological 'glues' to provide both temporary and more permanent adhesion. The practical consequence of colonisation by these organisms is biofouling - something that has plagued mariners for years - causing increased drag and, in extreme cases, corrosion. Might there be a biological ...

Contact angle hysteresis, adhesion, and marine biofouling.

Adhesive and marine biofouling release properties of coatings containing surface-oriented perfluoroalkyl groups were investigated. These coatings were prepared by cross-linking a copolymer of 1H,1H,2H,2H-heptadecafluorodecyl acrylate and acrylic acid with a copolymer of poly(2-isopropenyl-2-oxazoline) and methyl methacrylate at different molar ratios. The relationships between contact angle, co...

Prevention and protection of the effects of biocorrosion and biofouling minimizing the environmental impact

Biocorrosion and biofouling processes are mediated by microorganisms adhered to the metal surfaces or embedded in a gelatinous matrix called biofilm. Biofilms affect the interaction between metals and the environment not only in deleterious processes like corrosion but also in several biological processes applied to materials recovery and handling. The growth of the microorganisms capable to in...
