A coating includes an organosiloxane polymer and a mesoporous silica material bonded with the organosiloxane polymer. A monomer of the organosiloxane polymer is and the surface of the mesoporous silica material includes a hydrophilic group. A method for manufacturing the coating includes the following steps. Provide an organosiloxane polymer polymerized from a plurality of organosiloxanes including a terminal functional group. Provide a mesoporous silica precursor including a surface functional group. The organosiloxane polymer and the mesoporous silica precursor are blended in a solution, so that the surface functional group reacts with the terminal functional group to form a bond, and a mesoporous silica material is formed, as well as the surface of the mesoporous silica material includes a hydrophilic group. A film including a thickness of 0.1-500 μm is formed by the coating.
