A correlation of Raman data with the nanomechanical results of polymer nanomaterials with carbon nanoparticles

•PCL-based membranes with carbon nano-forms were studied.•SEM images monitored the spherulite size alteration in nanomaterials.•The Raman R1 factor determined the arrangement of the material.•The ΔG 'shift enabled the stress exerted on nano-carbons to be assessed.•The nanoindentation allowed for the estimation of the mechanical parameters.
