Abstract
A scaffold composite, and a preparation method and use thereof are provided. The preparation method includes: mixing a graphene oxide (GO) dispersion and a polylactic acid (PLA) dispersion, and subjecting a resulting mixed solution to curing and melt extrusion in sequence to obtain a 3-dimensional (3D)-printable GO/PLA composite wire; subjecting the 3D-printable GO/PLA composite wire to 3D printing to obtain a scaffold; and annealing the scaffold to obtain the scaffold composite.

A method for preparing a scaffold composite, comprising:
- mixing a graphene oxide (GO) dispersion and a polylactic acid (PLA) dispersion, and subjecting a resulting mixed dispersion to curing and melt extrusion in sequence to obtain a 3-dimensional (3D)-printable GO/PLA composite wire;
- subjecting the 3D-printable GO/PLA composite wire to 3D printing to obtain a scaffold;
- and
- annealing the scaffold to obtain the scaffold composite;
- wherein the annealing is conducted in an oven;
- the annealing is conducted at an oven temperature of 120° C. for 2 h;
- the melt extrusion is conducted at a screw speed of 16 rotations/minute (r/min);
- and
- wherein a mass ratio of GO to PLA in the 3D-printable GO/PLA composite wire is in a range of 0.001:1 to 0.0025:1.
