Abstract The feather grafted copolymer containing poly(dimethylaminoethyl methacrylate) (Feather-g-PDMAEMA) was synthesized via electron transfer atom transfer radical polymerization (ARGET ATRP), taking the carbonyl bromide groups on the feather surface as initiator and 2-(dimethylamino)ethyl methacrylate (DMAEMA) as grafting monomer. Subsequently, the DMAEMA grafted feather was quaternized by modification reagent bromoethane, and the feather grafted polymer with antibacterial properties was acquired. Furthermore, EDS, FT-IR, TGA, XRD and SEM were employed to characterize the element content, chemical structure, thermal stability, crystalline structure and surface morphology of the modified feather. The results of FT-IR and SEM analysis verified that 2-(dimethylamino)ethyl methacrylate was successfully grafted onto the surface of feather and the grafting rate of Feather-g-PDMAEMA could be as high as 84.7%. The results of XRD indicated that the crystallinity of feathers declined after grafting polymerization. It could be found from the results of TGA analysis, there was a certain decrease in the thermal stability of Feather-g-PDMAEMA. As revealed by antibacterial test, quaternized Feather-g-PDMAEMA possessed favorable antibacterial effect.
