We present the covalent coating of chemically exfoliated molybdenum disulfide (MoS) 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 MoS 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.
我们展示了基于功能性丙烯酸分子聚合的化学剥离二硫化钼（MoS）的共价涂层。该方法依赖于高效的重氮锚定反应来引发功能性涂层的原位自由基聚合和共价粘附。特别是，我们通过一种直接、快速且定量的合成方法成功地在剥离的MoS上实现了疏水性。通过包括X射线光电子能谱和热重-质谱在内的多种技术证明了共价功能化。这种方法代表了一种在二维材料上获得致密且均匀的功能涂层的简单通用方案。
