Vertically aligned nickel nanowire/epoxy composite for electrical and thermal conducting material

The vertically aligned nickel nanowire/epoxy composite for electrical and thermal conducting material was investigated in this research. The nickel nanowires were synthesized by template-assisted electro-deposition method using a high aspect-ratio anodic aluminum oxide (AAO) membrane. The diameter of the nickel nanowire was 200 nm, and the length of the nanowires was around 30 μm. The nickel nanowires were able to align vertically under external magnetic field while curing due to the ferromagnetic property of nickel nanowires. Epoxy with the nickel nanowires arranged in the horizontal and the vertical orientations along the applied external magnetic field of 300 ± 50 Gauss. The optical microscope images and Scanning Electron Microscopy (SEM) images revealed a good alignment of the nickel nanowires along with the external magnetic field.
