Preparation method of glass surface modified coating based on molecular brush technology

The invention discloses a preparation method of a glass surface modified coating based on a molecular brush technology, which belongs to the technical field of glass surface treatment and comprises the following steps: a microfluidic hydrolytic polymerization technology and a silane coupling agent grafting technology. The reaction time of the glass surface modification material developed in the invention and glass is only 2 min, and silane hydrolysis oligomerization reaction is realized by a microfluidic hydrolysis polymerization technology in an acidic environment through a microfluidic technology to form a 10-nano-scale short-chain oligomer as a molecular brush core. The addition of excessive water is accurately controlled, the temperature is constant, the molar ratio of acid to alkyl is adjusted, the siloxane polymerization speed is influenced, controllable living polymerization is realized, and uniform short-chain polysiloxane is obtained. The silane coupling agent grafting technology is a technology for
