FabricationofRFGFs:
ThefabricationofRFGFsinvolvesaseriesofprocesses,includingthesynthesisofgraphenefibers,functionalizationofspecificregions,andintegrationofthefunctionalizedgraphenefibersintodevicestructures.Graphenefiberscanbesynthesizedbyvariousmethods,suchaschemicalvapordeposition,electrospinning,andwetspinning.Electrospinninghasbeenwidelyusedtosynthesizegraphenefibersduetoitssimpleandscalableprocess,highyield,andlowcost.
Afterthesynthesisofgraphenefibers,thefunctionalizationprocesscanbecarriedoutinspecificregionstointroducedifferentfunctionalgroups.Themostcommonmodificationmethodsarechemi
