From: Applications of flexible polyimide: barrier material, sensor material, and functional material
Figure 1. Summary of the applications of flexible PI. The three main applications are barrier materials that include heat insulation and flame retardant material[11], electrical insulation material[12], and sound absorbing material[13]; component materials used in humidity sensors[14], force sensors[15], temperature sensors[16], gas sensors[17] and other sensors; functional materials used as battery separator[18], colorless substrate[19], luminescent material[20], memory material[21], etc.
