  • Porous GO layer deposited on PES nonwovens
  • Plasma reduction-exfoliation triggered by atmospheric plasma generated in pure N2 utilizing roll-to-roll DCSBD plasma reactor

  • Mimicking of R2R treatment at speed 2.5 cm.s-1

  • Proof-of-concept
  • Problems with surface uniformity of rGO layer It is not a result of plasma treatment, but it is crucial to prepare a porous GO film on NWs of required quality (needs optimization)
