Study of the electrical threshold of the PLA/MWCNT composite obtained by combining solvent casting (20% loaded Masterbatch) and extrusion as dilution. Nano-filler percentages between 2 and 15%. PEG study: study of the electrical conductivity of the PLA/MWCNT/PEG composite by varying the carbon nanotubes and polyethylene glycol. In this case the PEG acts as a charge dispersant, increasing the electrical conductivity. PEG lignin comparison: study of the increase in electrical conductivity of PLA/MWCNT composite with 2 charge dispersants, one artificial (PEG) and one reused natural (lignin). Type of version of the dataset: FINAL DATASET Total size: 29 KB Exp 1 DSC: Data of thermal tests Solvent optimisation: study of the effect of the selected solvents on the melting and glass transition points of PLA. MWCNT optimisation: study of the effect of different amounts of MWCNT on the melting and glass transition points of PLA. PEG: study of the effect of different amounts of PEG on the melting and glass transition points of PLA Type of version of the dataset: FINAL DATASET Total size: 120 KB Exp 1 mecánicas: Solvent Optimisation: study of the influence of solvents on the mechanical tensile strength of PLA PLA MWCNT: study of the influence of different percentages of MWCNT (5, 10 and 15 wt.%) on the mechanical tensile strength of PLA. PEG: study of the influence of different percentages of PEG (1, 2 and 3 wt.%) on the tensile strength of PLA/MWCNT composite at 5% loading. Type of version of the dataset: FINAL DATASET Total size: 33 KB Exp 1 Reología: Solvent optimisation: study of the influence of solvents on the viscoelastic behaviour of PLA for further processing by FDM 3D printing.
