Carbon nanotube/TiO2 modified UV resin coating with antistatic and antibacterial functions

Abstract

The invention discloses a carbon nanotube / TiO2 modified UV resin coating with antistatic and antibacterial functions. The carbon nanotube / TiO2 modified UV resin coating with antistatic and antibacterial functions is formed through compounding UV resin with a photoinitiator, an active diluent and various assistants; the resin is epoxy acrylic resin; and carbon nanotubes (CNTs) with the surface being grafted with methyl methacrylate (MMA) and nano-TiO2 with the surface being hydrophobically modified are added to the UV coating. The invention also discloses a production method of the carbon nanotube / TiO2 modified UV resin coating with antistatic and antibacterial functions. The method comprises the following steps: 1, purifying the CNTs, and grafting the surface of the CNTs with the MMA; 2, hydrophobically modifying the surface of the nano-TiO2; and 3, modifying an epoxy acrylic resin coating with the CNTs with the surface being grafted with the MMA and the nano-TiO2 with the surface being hydrophobically modified. The carbon nanotube / TiO2 modified UV resin coating has good antistatic and antibacterial functions.
