In this work, NPC ﬁlm with controllable Revised 1 February 2018 density was prepared by electroless plating using polystyrene (PS) templates and copper azide with large Accepted 10 February 2018 density and enhanced initiation performance was subsequently in situ fabricated by NPC ﬁlm with proper Available online 14 February 2018 density. The tunability of NPC density or porosity was controlled by adjusting the loading amount and particle size of PS. For copper azide fabrication, the proper density of NPC should be slightly less than Keywords: 3 3 the ideal value of 1.12 gcm . The density of copper azide prepared by NPC
