Raw materials, suspensions, and porous scaffolds.

Notes: (A) Optical and SEM micrographs of raw materials. (B) Optical micrographs of composite powder/NMP suspensions (left, 0 hour after sonication; right, 72 hours of storage after sonication). (C) Optical micrographs of porous scaffolds. S1, PEEK–10 wt% nano-HAP; S2, PEEK–10 wt% nano-HAP–1 wt% GNSs; S3, PEEK–10 wt% nano-HAP–0.8 wt% GNSs–0.2 wt% CNTs; S4, PEEK–10 wt% nano-HAP–0.5 wt% GNSs–0.5 wt% CNTs; S5, PEEK–10 wt% nano-HAP–0.2 wt% GNSs–0.8 wt% CNTs; S6, PEEK–10 wt% nano-HAP–1 wt% CNTs.

Abbreviations: CNTs, carbon nanotubes; GNSs, graphene nanosheets; HAP, hydroxyapatite; NMP, N-methyl-2-pyrrolidone; PEEK, polyetheretherketone; SEM, scanning electron microscopy.
