This study presents the covalent coating of chemically exfoliated molybdenum disulfide (MoS2) using the polymerization of functional acryl molecules, achieving hydrophobic functionalization. The successful covalent functionalization was confirmed through various techniques, providing a simple and general protocol for dense and homogeneous functional coatings on 2D materials.
We present the covalent coating of chemically exfoliated molybdenum disulfide (MoS2) based on the polymerization of functional acryl molecules. The method relies on the efficient diazonium anchoring reaction to provoke the in situ radical polymerization and covalent adhesion of functional coatings. In particular, we successfully implement hydrophobicity on the exfoliated MoS2 in a direct, fast, and quantitative synthetic approach. The covalent functionalization is proved by multiple techniques including X-ray photoelectron spectroscopy and TGA-MS. This approach represents a simple and general protocol to reach dense and homogeneous functional coatings on 2D materials.
