An effective micromechanical technique to prepare graphene multilayers on low density polyethylene (LDPE) substrates was carried out. This fabrication method, based on the spreading of graphite nanoplatelets (GNP) onto a LDPE film surface by using shear stress and friction force, allows to obtain large area specimens. The morphological and structural properties of the GNP precursor and graphene multilayers supported by LDPE were investigated. The graphene-LDPE samples showed negative photoconductivity under white-light illumination with an optical power density of 84.6 mW/cm2, varying the bias voltage from -120 to 120 mV

Abstract
An effective micromechanical technique to prepare graphene multilayers on low density polyethylene (LDPE) substrates was carried out. This fabrication method, based on the spreading of graphite nanoplatelets (GNP) onto a LDPE film surface by using shear stress and friction force, allows to obtain large area specimens. The morphological and structural properties of the GNP precursor and graphene multilayers supported by LDPE were investigated. The graphene-LDPE samples showed negative photoconductivity under white-light illumination with an optical power density of 84.6 mW/cm2, varying the bias voltage from -120 to 120 mVFile in questo prodotto:
