Application of Janus nanoparticles as adhesive in dental repair filling materials

The invention relates to application of Janus nanoparticles as an adhesive in dental repair filling materials, belonging to the field of dental repair. The area of different chemical composition regions, chemical composition, particle size distribution, double-bond group number and other important influencing factors of the Janus nano composite material are accurately controlled to prepare the nano-sized Janus material with polymerizable unsaturated double bonds at the hydrophobic side. The synthesized Janus nanoparticles are used instead of HEMA (hydroxyethyl methacrylate) (the hydrophilic component and hydrophobic component materials in the widely used stable adhesive at present) for bonding the filler resin-tooth interface to solve the problems of overhigh hydrophilicity, easy hydrolysis and destroy of the bonding interface and obvious cytotoxicity in the existing HEMA, constructing the long-acting stable adhesive layer, and enhancing the durability of the bonded material. 本发明涉及种Janus纳米颗粒作为粘接剂用于牙科修复填充材料的应用
