Model silicone foul-release coatings with controlled molecular architecture were evaluated to determine the effect of compositional variables such as filler loading and crosslink density on pseudobarnacle attachment strength. Pseudobarnacle adhesion values correlated with filler loadings in both condensation and hydrosilylation-cured silicones. Variation of crosslink density of hydrosilylation-cured silicones had an insignificant effect on attachment strength. X-ray photoelectron spectroscopy (XPS) indicated that the mode of failure upon detachment of the pseudobarnacle was dependent upon the crosslink density; samples with high crosslink density failed cohesively within the silicone.
对具有可控分子结构的模型有机硅防污涂层进行了评估，以确定诸如填料含量和交联密度等组成变量对伪藤壶附着强度的影响。在缩合固化和硅氢加成固化的有机硅中，伪藤壶的粘附值均与填料含量相关。硅氢加成固化有机硅交联密度的变化对附着强度影响不显著。X射线光电子能谱（XPS）表明，伪藤壶脱离时的失效模式取决于交联密度；交联密度高的样品在有机硅内部发生内聚破坏。
