Superhydrophobic silicone fouling-release (FR) nanocomposite coatings have gained considerable interest as an eco-friendly and economic solution to combat biofouling problems of ship hulls. In this work, graphene oxide anchored with alumina nanorods (GO-Al₂O₃ NRs) sheet hybrids were fabricated via a two-phase method. A ternary nanocomposite series of elastomeric silicone/GO-Al₂O₃ hybrid NRs sheet coating was developed via solution-casting method. γ–Al₂O₃ NRs of 150 nm in length and 20 nm in diameter were fastened between GO nanosheets and conformably coated with silicone layers. Different concentrations of GO-Al₂O₃ hybrid NRs sheet fillers were inserted in the silicone composites to study the structure property relationship. Nanocomposites’ surface characteristics, such as superhydrophobicity, surface free energy (SFE), and rough topology were investigated here. The physical and …
