Résumé : |
An explicit review has been made regarding non-toxic fluorinated polyurethane and silicone polyurethane fouling release coatings. An insight into the release mechanisms through which these coatings operate and the polymer properties which influence bioadhesion is discussed in detail. The formulation and synthesis of fluorinated polyurethane and silicone polyurethane coatings and the criteria required for designing effective fouling release coating is discussed. |

FOULING RELEASE COATINGS
MECHANISMS OF FOULING RELEASE : Chemical bonding - Electrostatic interactions - Mechanical interlocking - Diffusion - Fracture mechanics
PROPERTIES INFLUENCING BIOADHESION : Correlation of surface energy and bioadhesion - Correlation of elastic modulus and bioadhesion - Correlation of polymer structure and bioadhesion
- Correlation of thickness and bioadhesion
FLUORINATED FOULING RELEASE COATINGS : History and development
- Characteristics of fluoropolymers - Synthesis of fluorinated polyurethane coatings (fluorinated polyols, isocyanates (curing agent) - Other developments in fluorinated polyurethane coatings - Orientation of fluorochimical "Tails" - Formulation aspects (polytetrafluoroethylene (PTFE), pigments, additive, solvents
- Design criteria for fouling release fluoropolymer coatings
SILICONE FOULING RELEASE COATINGS : Unique properties of polydimethylsiloxane (PDMS) - Synthesis of silicone coatings
polyurethane - silicone - hydrocarbon coatings, polybutadiene-silicone coatings, silicone-urethane coatings, one pack moisture-cured silicone-polyurethane coating
- Design criteria for fouling-release silicone coatings
TESTING OF FOULING RELEASE COATINGS : Fouling test (ASTM D5618 - Measurement of barnacle adhesion strength in shear
* ASTM D5479 - Biofouling resistance of the marine coatings partially immersed, accelerated laboratory screening tests : ASTM D5589 and D 5590, another accelerated laboratory screening test
- Contact angle measurements and surface energy calculations (geometric mean, acid/base) - Elastic modulus and plastic hardness (Flexibility and thoughness)
