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.
藤壶能够有效地附着在水下的大多数表面上。在释放其永久性粘合剂之前，对相应表面进行去湿处理，这在附着过程中起着重要作用。可能，一种能够干扰这个过程的表面可能具有特殊的防污性和防污释放能力。因此，在波罗的海进行了为期 13 周的野外实验中，测试了由聚二甲基硅氧烷（PDMS）制成的开孔泡沫与平板 PDMS 样品一起作为对照。每周监测贻贝藤壶 (= Amphibalanus) improvisus 的附着和污损密度发展情况。在 PDMS 泡沫上的总附着接近零，并且少数附着的藤壶在最初附着后 1 周内无法留在 PDMS 泡沫上。PDMS 泡沫硬度的变化并没有影响这些结果。开孔 PDMS 泡沫系统可能是开发新的创新性防污策略的有前途的工具。
