Barnacles are able to effectively adhere to most surfaces underwater. Dewetting of the corresponding surface prior to the release of their permanent adhesive plays an important role in the attachment process. Possibly, a surface that is able to interfere with this process may have exceptional fouling repellence and fouling release abilities. Therefore, open-pored foams made from polydimethylsiloxane (PDMS) were tested together with flat PDMS samples as controls in a 13-week-long field experiment in the Baltic Sea. On a weekly basis, both settlement and fouling density development of the bay barnacle Balanus (=Amphibalanus) improvisus were monitored. The overall settlement was close to zero on PDMS foams and the few attached barnacles were not able to stay on the PDMS foams longer than 1 week after initial settlement. Changes in the stiffness of the PDMS foams did not affect these results. Open-pored PDMS foam systems may be a promising tool in the development of new, innovative antifouling strategies.

在自然条件下，多孔硅胶基材可抑制藤壶的永久性附着

藤壶能够有效地附着在水下的大多数表面。在释放永久粘合剂之前，相应表面的去湿在附着过程中起着重要作用。可能，能够干扰该过程的表面可能具有出色的防污和除污能力。因此，在波罗的海进行的为期 13 周的现场实验中，由聚二甲基硅氧烷 (PDMS) 制成的开孔泡沫与作为对照的扁平 PDMS 样品一起进行了测试。每周，海湾藤壶Balanus (= Amphibalanus) improvisus 的沉降和污垢密度发展被监控。PDMS 泡沫的总体沉降接近于零，并且少数附着的藤壶在初始沉降后无法在 PDMS 泡沫上停留超过 1 周。PDMS 泡沫硬度的变化不会影响这些结果。开孔 PDMS 泡沫系统可能是开发新的创新防污策略的有前途的工具。
