In recent years

antibacterial modification of polymer materials by grafting has attracted extensive attention because it can endow polymer materials with excellent antibacterial properties without changing original characteristics of polymer. And antibacterial polymer materials have been widely used in our lives. In this paper

some antibacterial groups (ones with

N

-halogenated amine structures

positively charged antibacterial active ones

etc.

) are reviewed

which are commonly used in antibacterial modification of polymer materials by grafting at home and abroad. Additionally

the antibacterial effect and mechanism of the above groups in polymer materials are introduced

and the future development trend of antibacterial polymer materials by grafting modification is prospected.
