研究了一种新型的基于聚硅氧烷基体的光聚合网络膜，该基体含有不同量的聚氧乙烯（P3）或全氟己基乙基（F）悬挂侧链。对于含有小于10wt%的P3和F的膜，润湿性和弹性模量与光聚合网络基质的润湿性和弹性模量相似。然而，角分辨X射线光电子能谱测量证明，F悬挂链的膜的表面高度富集氟，这取决于P3和F的量和它们在膜中的相对比例。膜的生物性能进行了评估，对一个新的广泛的和入侵的海洋生物污染物，serpulid Fellomatus enigmaticus。还将硅藻盐生舟形藻作为常规模式生物进行测定以用于比较。富含P3的膜能更好地抵抗F.谜一样的。
Novel photopolymerized network films based on a polysiloxane matrix containing varied amounts of polyoxyethylene (P3) or perfluorohexylethyl (F) dangling side chains were investigated. For films containing less than 10 wt % P3 and F, the wettability and elastic modulus were similar to those of the photopolymerized network matrix. However, angle-resolved X-ray photoelectron spectroscopy measurements proved that the surface of films with F dangling chains was highly enriched in fluorine depending on both the amount of P3 and F and their relative ratio in the films. The biological performance of the films was evaluated against a new widespread and invasive marine biofoulant, the serpulid Ficopomatus enigmaticus. The diatom Navicula salinicola was also assayed as a conventional model organism for comparison. Films richer in P3 better resisted the settlement and promoted the release of calcified tubeworms of F. enigmaticus.
