  Patterning of graphene into micro- and nano-ribbons allows for the tunability
in emerging fields such as flexible electronic and optoelectronic devices, and
is gaining interest for the production of more efficient reinforcement for
composite materials. In this work we fabricate micro-ribbons from CVD graphene
by combining UV photolithography and dry etching oxygen plasma treatments.
Raman spectral imaging confirms the effectiveness of the patterning procedure,
which is suitable for large-area patterning of graphene on wafer-scale, and
confirms that the quality of graphene remains unaltered. The produced
micro-ribbons were finally transferred and embedded into a polymeric matrix and
the mechanical response was investigated by in-situ mechanical investigation
combining Raman spectroscopy and tensile/compressive tests.
