Carbon nanotube-based detonating fuse and explosive device using the same

An explosive device comprising:

• an explosive;
• and
• a detonating fuse inserted into the explosive and comprising at least one carbon nanotube (CNT) wire, the at least one CNT wire comprising a plurality of carbon nanotubes (CNTs) and an oxidizing material coating each of the plurality of CNTs, wherein a diameter of the at least one CNT wire ranges from 10 micrometers to 100 micrometers, wherein the oxidizing material is metal salt, the metal salt is selected from the group consisting of nitrate, potassium nitrate or ammonium nitrate.

A detonating fuse comprising:

• at least one carbon nanotube (CNT) wire comprising a plurality of carbon nanotubes (CNTs) and an oxidizing material coated on an outer surface of each of the plurality of CNTs, wherein the plurality of CNTs are joined end-to-end along and parallel to an axis of the at least one CNT wire by van der Waals attractive force between them, and a diameter of the at least one CNT wire ranges from 10 micrometers to 100 micrometers, wherein the oxidizing material is selected from the group consisting of nitrate, potassium nitrate or ammonium nitrate.
