| Résumé : |
Maleic anhydride grafted graphene oxide (GOMA) monomer was prepared by modifying the graphene oxide (GO) with hexachlorocyclotriphosphazene (HCCP), ethylenediamine (ETA) and maleic anhydride (MA). Then a polymeric retanning agent, abbreviated as poly(GOMA-MA-VA) was synthesized from GOMA, MA and vinyl acetate (VA) by free radical polymerization. The structures of GOMA and poly(GOMA-MA-VA) were characterized by Fourier transform infrared (FTIR) spectroscopy, Raman and X-ray photoelectron spectroscopy (XPS), simultaneously, the flammability, UV-resistance as well as the thermal stability and mechanical properties of re-tanned leathers were also investigated. Results show that GO grafted by polymer presents well dispersing stability and can penetrate into collagen fibers to form strong combination with fibers. Furthermore, this novel multifunctional retanning agent can efficiently improve the flame retardance, ultraviolet (UV) resistance, thermal stability and mechanical properties of resultant leather. |
