摘要

Polydimethylsiloxane (PDMS)-based antifouling polymers with tunable self-healing capabilities in aqueous conditions were fabricated by incorporating amphiphilic segments and Fe

–catechol coordination crosslinking. The self-healing efficiency achieved 98% within 24 h in an aqueous environment. No bacterial adhesion was observed at the scratch site after repair.

Abstract

Development of polymers with underwater self-healing and antifouling properties is crucial

particularly in harsh marine environments. In this study

polydimethylsiloxane (PDMS)-based antifouling p

olymers with tunable self-healing capabilities in aqueous conditions were fabricated by incorporating amphiphilic segments and Fe

-catechol dynamic coordination crosslinking. The microphase formed within the PDMS matrix imparted static antifouling properties to the coatings. The mechanical properties of the damaged sample were restored at room temperature in an aqueous environment for 24 h

achieving a self-healing efficiency of almost 100%. The synthesized material exploited the dynamic coordination between Fe

and catechol to facilitate underwater self-healing. No bacterial adhesion was observed at the scratch site after the coating was repaired. This material enables the long-term antifouling and autonomous repair of marine vessels and sensors

thereby reducing maintenance costs.
