Figure 2From: Facile synthesis 3D flexible core-shell graphene/glass fiber via chemical vapor depositionSEM images before and after deposition and Raman spectra of the 3D graphene/glass fibers. (a) (b) The SEM images before and after deposition of the graphene for 20 min on the glass fiber membrane surface. (c) SEM image of the 3D graphene/glass fibers with the different diameter. (d) Raman spectra of the 3D graphene/glass fibers deposited for 10 and 20 min.Back to article page
