제목 Universal Solvent-free Surface Modification of Inorganic Particles via a Facile Mechanical Grinding
초록 Polysiloxanes (PSOs) consisting of siloxane backbone with organic side-groups have been widely used in our life due to their non-toxicity, various functionalities, and good stabilities. The PSOs can react with inorganic materials in the presence of surface hydroxyl groups, grafting to the surface as a few nanometers long PSO brush. Herein, we present a solvent-free PSO grafting method onto surfaces of inorganic particles by using simple ball milling process. By the ball milling of nano/micro inorganic particles and PSOs mixture, the particles are grinded and simultaneously reacted with PSOs to modify the surface. This method allows one-pot large-scale surface modification without additional solvents and chemicals, which can be applied to most inorganic materials including metals, oxides, and metal-oxides. In addition, depending on the side-groups of PSOs, the surfaces of the inorganic particles have various functionalities, such as hydrophobicity and cross-linking ability.
