TEM results of MWNTs (a) CNT , (b) CNT 8–15 nm, (c) CNT 20–30 nm, and (d) CNT 30–50 nm.
Schematic flow chart of LIGA process and the shape of the tensile test sample.
SEM images of the (a) deposited pure copper and Cu/CNT composite samples (after using alcohol to reveal grain boundaries) with different CNT diameters: (b) CNT 1.5–3 nm, (c) CNT , (d) CNT 8–15 nm, (e) CNT 20–30 nm, and (f) CNT 30–50 nm.
(a) Tensile stress-strain curve of pure Cu and Cu/CNT composites with different diameters and (b) averaged tensile strengths versus CNT diameters of Cu/CNT composites.
SEM images of fractured morphologies of (a) pure copper and (b) Cu/CNT (20–30 nm) composite. A TEM image of the fractured Cu/CNT (c) shows trapped CNTs in Cu matrix.
