Polyimides have many applications in microelectronic industries. They are often used in the electronics industry for flexible cables, as friction elements in data processing equipment, and as insulating films on magnet wires. For example, in a laptop computer, the cable that connects the main logic board to the display (which must flex every time the laptop is opened or closed) is often a polyimide base with copper conductors. Polyimides are used as high-temperature adhesives in semiconductor industries and aerospace industries. They are used for the struts and chassis in cars as well as some 

Recently, polyimides have drawn considerable attention for the development of membranes for fuel cells. In polymer membrane fuel cells, nafion is widely used as membrane. However, the nafion membrane cannot withstand high temperature ( 80 °C), so research on the development of polyimide based fuel cell membranes has started [169-173]. Polyimides also find applications in the development of gas separation membranes because of their compact ring structure and less free volume, which restricts the passage of gases.
