摘要: Abstract In this study two surface sensitive methods, i.e. quartz crystal microbalance with dissipation monitoring (QCM-D) and ellipsometry, were used for erosion measurements of a rosin-based marine antifouling paint binder. Thin films the binder applied on sensor surfaces by means spin-coating effect water velocity over film, temperature or ionic strength was investigated. Both acoustic QCM-D model optical ellipsometry gave comparable results. The initial 2–50 nm rapid top layer followed steady-state rate until end experiment. For example, 12 nm/24 h in artificial seawater at 23 °C flow 200 μl/min as measured QCM-D. increased temperature. Ionic had no At low velocities highly dissipative indicating filled formation deposits surface. New characterization techniques that are able to mechanisms nanometre scale sought binders get more technically complex containing, nanoparticles enzymes. Surface methods could be rapidly screen different chemistries additives during development process.
