Transport and antifouling properties of papain-based antifouling coatings

- An antifouling coating has been formulated using papain adsorbed in activated carbon.
- EIS technique is a great tool to predict the water diffusivity in the coatings.
- Immersion tests showed the excellent antifouling action of papain.
- The use of papain can eliminate the negative environmental impact caused by biocides.
