Is Young's Modulus a Critical Coating Property Determining Fouling‐Release Performance of Marine Coatings?

open access: yesAdvanced Engineering Materials, EarlyView.
The release of foulers from protective marine coatings is determined by several interrelated material properties, including the strength of Young's modulus, the flexibility of chain segments, the surface free energy, and the magnitude of hydrodynamic stress.
