Biotic sol-gel coating for the inhibition of corrosion in seawater

Publié le 4 juin : Source Gittens, J. E. ; Wang, H. ; Smith, T. J. ; Akid, R. ; Greenfield, D.

In marine environments corrosion is exacerbated by formation of destructive biofilms containing sulphate-reducing bacteria, which promote corrosion by forming corrosive species, such as H2S. Corrosion-causing biofilms are often resistant to inactivation by biocides since the biofilm bacteria are protected by a matrix of exopolymeric substances (EPS). Paradoxically, a biofilm of the endospore-forming Paenibacillus polymyxa can actually inhibit corrosion. Sol gel technology and immobilized...

Linking Microbiologically Influenced Corrosion to Microbiological Activity Using Molecular Microbiological Methods Microorganisms are ubiquitous in geological environments, from the surface of the earth to the deepest layer of the ocean’s crust. Some microorganisms are useful, while others can be very harmful. In oil and gas production, microbiological activity is one of the biggest contributors to metal infrastructure corrosion. While there are some available solutions to mitigate microbiologically influenced corrosion (MIC), a big challenge is to make the connection between corrosion damage, such as pitting, and the activity of microorganisms.1 While still used, traditional culture-based methods...

Radical Cation Initiated Surface Polymerization on Photothermal Rubber for Smart Antifouling Coatings

Radical Cation Initiated Surface Polymerization on Photothermal Rubber for Smart Antifouling Coatings Smart coatings: Radical cations are generated when rubber is exposed to iodine treatment. These radical cations not only facilitate photothermal conversion, but also initiate surface polymerization. A successful example of poly(N‐isopropylacrylamide) (PNIPAM) brushes grafted on darkened rubber demonstrates that the combination of thermoresponsive polymers with photothermal conversion opens a new avenue for exploiting light‐triggered bacteria‐killing and antifouling coatings. Abstract Biofouling on surfaces of various materials has attracted considerable attention in biomedical and...
