These materials have several potential applications, such as electromagnetic interference (EMI) shielding, microwave absorbers, gas sensors, display units, junction devices, ect.[4, 5].
Conductive polymers are useful as shielding materials in applications involving high data-rate electronics (eg., supercomputers), and in aerospace applications, where weight is a constraint.

Requirements of heavier load and higher velocity for friction materials in advanced brake and clutch system can be met because oxidation resistance at elevated temperature and energy absorption capacity are markedly improved if this kind of fiber is used to the friction materials [5,6].
And also, the tiny fins can augment surface area of fiber and improve the filtering and sound absorption capabilities of porous materials.
