PDMS-based fouling release coatings have promising applications in the fields of marine fouling control. However, development of silicone-based coatings with good antifouling / fouling-release property under relative static conditions remains challenging. In this work, a new PDMS-based nanocomposite coating consisting of PDMS matrix and nanofiller of copper@carbon core-shell nanoparticles was developed. Uniformly dispersed Cu@C core-shell in the PDMS matrix enhance the antifouling ability. The PDMS with low surface energy endows the composite coatings with hydrophobicity thus fouling release property. The introduction of Cu@C core-shell/PDMS improves both the Young's modulus, tensile strength and the elongation at break. Furthermore, laboratory bioassay against diatom adhesion and field tests indicated that the PDMS-based nanocomposite coatings with Cu@C core-shell exhibited outstanding antifouling / fouling-release property even under static conditions, showing promising application in marine antifouling.

基于 PDMS 的污垢释放涂层在海洋污垢控制领域具有广阔的应用前景。然而，在相对静态条件下开发具有良好防污/除污性能的有机硅涂层仍然具有挑战性。在这项工作中，开发了一种基于 PDMS 的新型纳米复合涂层，该涂层由 PDMS 基体和铜@碳核壳纳米粒子的纳米填料组成。PDMS 基质中均匀分散的 Cu@C 核壳增强了防污能力。具有低表面能的 PDMS 赋予复合涂层疏水性，从而具有脱污性能。Cu@C核壳/PDMS的引入提高了杨氏模量、拉伸强度和断裂伸长率。此外，
