Fabrication and properties for novel graphene oxide powder with extra large interlayer spacing and high reactivity

Silicon dioxide nanoparticles decorated on graphene oxide nanosheets and their application in poly(l-lactic acid) scaffold

“…For GO@SiO 2 hybrids, the G peak was shifted towards higher wave number (1589 cm −1 , 1591 cm −1 , 1592 cm −1 for GO@SiO 2 -5, GO@SiO 2 -10, GO@SiO 2 -15, respectively). Moreover, the peak intensity ratio (I D /I G ) increased from 0.92 for GO to 0.94, 0.96, 0.97 for GO@SiO 2 -5, GO@SiO 2 -10, GO@SiO 2 -15, respectively, indicating improved disorder level of the layers for GO@SiO 2 hybrids, which might lead to the expanded layer spacing as previous reported [49] , [50] , [51] .…”
