A novel environment-friendly system is proposed tofabricate polymer brush, which has the advantages including non-toxic and inexpensive initiator(eosin Y), visible-light exposure(λ= 515 nm), water medium and ambient environment. The experimental results from UV-Vis spectroscopy, AFM-based single molecule force spectroscopy(SMFS) and other measurements indicate thata polymer brush with a living nature is fabricated via free radical polymerization. This polymer brush may find applications incoatings, bio-interfaces and so forth.
