From: Robust Surface-Engineered Tape-Cast and Extrusion Methods to Fabricate Electrically-Conductive Poly(vinylidene fluoride)/Carbon Nanotube Filaments for Corrosion-Resistant 3D Printing Applications

Figure 4

Scanning electron microscopy (SEM) shows the structure change of 95 wt%P2-5 wt%C1 composite powder (before extrusion) at 100,000 times magnification (A) without ball-milling, and, (B–D) after ball-milling for (B) 10 minutes, (C) 30 minutes, and (D) 60 minutes.
