Fabrication of pure aluminum nanowires by using injection molding process in ambient air

• We fabricated pure aluminum nanowires in ambient air.
• Below 650 °C, the Al nanowires were synthesized by using injection molding process.
• The substrate of AAO should be replaced by an electroless nickel deposition.
• The nanowires were crystalline and with the average diameter of 60 nm.

A simple method to prepare aluminum nanowires was achieved by using the injection molding process in the air. The Al nanowires were made with the average diameter of 60 nm and length of several micrometers. The difference between mold dimension and nanowires was caused by removing the outer oxide shell of Al nanowires. XRD, EDS and SAED results showed that the Al crystalline nanowires were fabricated exactly. The proposed concept successfully established a simple and low-cost method to have high-temperature and soft nano-materials under the non-vacuum surroundings.
