Electrochemical (pre)treatments to prevent biofouling
Résumé
In order to prevent the formation of a biofilm on the surface of materials in an aqueous environment various strategies could be developed. Notably following an electrochemical route it is possible to apply a potential which could lead to (i) oxidation of halide anions leading to the formation of biocidal molecules, (ii) O2 reduction leading to H2O2, (iii) water reduction leading to H2 bubbles or (iv) a low-intensity electric potential. Moreover an electrochemical method could be used to nano or microstructure the material surface or to deposit on the material a coating which would avoid protein adsorption or microorganism attachment and therefore the formation of a biofilm, this coating could be of an inorganic or an organic film.
