(a) SU8 patterned by UV-lithography process loaded with nanoparticles (0.6 wt% of reduced graphene oxide). (b,c) SEM images of two regions of the same CNT-SU8 sample. In (b) the nanotubes appear to be well dispersed while c shows a local cluster of tightly interlaced CNTs. (d,e) TEM images showing local CNT clusters. In (be) the CNT volume fraction is 0.28 %.
