However, conventional absorbers still face challenges such as imperfect impedance matching, high reflection losses, and complex fabrication methods, limiting their use in advanced electromagnetic platforms. In this study, a graphene nanoparticle-embedded metamaterial absorber is designed, fabricated, and evaluated for high-efficiency absorption at 8.2 GHz. The graphene oxide-polyvinyl alcohol (GO-PVA) substrate is prepared using a 1:5 ratio of graphene nano powder and PVA with distilled water, forming a uniform, flexible dielectric film with a dielectric constant (εᵣ) = 6.154 and loss tangent (tan δ) = 0.00245 over the 8–10 GHz range.

However, conventional coatings often fail to balance antifouling and anti-corrosion performance with mechanical stability. In this paper, a pH-responsive antibiofouling composite coating (OC-MCSX) with slippery liquid-like properties and long-term functionality was developed. The coating was fabricated by covalently grafting PDMS brushes into an epoxy matrix via thermal crosslinking, while incorporating microencapsulated 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT) as a functional filler. The highly crosslinked network significantly enhanced the OC-MCSX's mechanical strength, whereas the pH-responsive microcapsules enabled precise controlled release of antifoulants. Furthermore, this design integrates a low-surface-energy fouling-release mechanism with a contact-inhibition antifouling strategy. Through the synergistic effects of surface interface regulation and controlled-release antifouling agents, it effectively suppresses the adhesion and accumulation of biofouling, thereby achieving stable and long-lasting antifouling performance.
