Abstract Anti‐biofouling performance plays a critical role for marine application of microwave absorption materials (MAMs) to maintain their stable and durable capacity. However, anti‐biofouling properties are generally ignored by traditional MAMs that merely pursue strong (MA) capability. Herein, this work reports the first time preparation ternary Cu 1.8 S/reduced graphene oxide/oleylamine (Cu S/rGO/OLAM) composite integrated with outstanding properties. S nanoparticles OLAM films sequentially generated on rGO one‐pot solution‐phase thermal decomposition method. The copper vacancy defects in can effectively induce dipole polarization. surface‐coated layers not only provide abundant heterogeneous interfaces interfacial polarization, but also improve hydrophobicity reduce organism adhesion. release ions damage bacterial algal cell membranes protein denaturation, contributing enhancement high conductive loss sharp edge both MA Consequently, S/rGO/OLAM exhibits remarkable capability, minimum reflection value −56.2 dB an effective bandwidth 9.68 GHz. Additionally, shows survival rates bacteria algae as low 4% 35%, respectively.
