From: 3D printing of graphene-based polymeric nanocomposites for biomedical applications
Technique | Matrix | Filler | Properties | Ref. |
|---|---|---|---|---|
SLA | Photopolymer (Envision TEC PIC 100 resin) | GO | 0.2wt.%GO increased 62.2% and 12.8% the tensile strength and ductility, respectively of the printed composite. | [54] |
DIW | Polyaniline (PANI) | Specific capacitance of the printed supercapacitor: 1329 mF cm− 2. | [56] | |
Polydimethylsiloxane (PDMS) | The printed device exhibited a resistivity of 1660 Ω.cm at a low GO percolation threshold (0.83 vol.%) | [57] | ||
Epoxy | Graphene | Printed composites with 10 wt.% of graphene presented flexural modulus of 3.2 GPa and bulk resistivity of 1 × 103 Ω.m, i.e., five orders of magnitude lower than that of the neat epoxy. | [58] | |
SLS | PA | Tensile modulus for PA-rGO compared to PA (221 ± 17 vs 149 ± 26 MPa) and similar tensile strength. | [59] | |
FDM | ABS | Electrical conductivity increased to 1.78 × 10− 7 and 1.05 × 10− 3 S.m− 1 with the addition of 0.4 and 5.6 wt% of graphene, respectively | [60] |
