“…In addition grafting of polymers onto these surfaces interests us for designing new functional composite materials which have the excellent properties both of nanoparticles as mentioned above and of grafted polymers, such as photosensitivity, biorepellent activity, antibacterial activity, and pharmacological activity (Tsubokawa, 2007). We have succeeded in the grafting of various polymers such as vinyl polymer (Tsubokawa et al, 1988a;Tsubokawa et al, 1990;Fujiki et al, 1990;Tsubokawa et al, 1992a), polyester (Tsubokawa et al, 1982;Tsubokawa et al, 1983), polyether (Tsubokawa et al, 1986;Tsubokawa et al, 1988b), poly(organophosphazene) (Tsubokawa et al, 1992b), and poly(dimethysiloxane) (Tsubokawa et al, 1992c) onto silica nanoparticle and carbon black surfaces using surface functional groups as grafting sites. Furthermore, many experimental attempts by other researchers also have been made to graft polymers onto silica nanoparticle and carbon black surfaces.…”
