Surface-initiated atom transfer radical polymerization (SI-ATRP) is a class of highly controllable surface modification methods, and grafted polymer brushes provide an ideal model for research in surface science and engineering
Recently, Zhou Feng, a researcher at the State Key Laboratory of Solid Lubrication, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, developed a surface polymer brush grafting method with high mechanical stability from the perspective of tribology
The key to this method is to construct an initiator coating (Persistent Initiation Coating, PIC) with high mechanical stability and sustained initiation activity, as shown in Figure 1, by introducing the initiator into the inorganic sol-gel nanocoating , and then surface-initiated graft-modified polymer brushes
When the grafted polymer brushes were worn out, PIC could still trigger new polymerization reactions (Fig.
PIC has good bonding strength on different material surfaces and can be implemented on different substrate surfaces
This study provides a new way to construct wear-resistant, low-friction, reinitiation polymer brush coatings, and provides more possibilities for the practical application of polymer brush surface materials
