Preparation of flexible hollow PANI/Feixu composite fibers

Feixu, floccule in the air, is a common phenomenon in nature, sending their seeds to distant place to reproduce. In order to make the seeds flying farther, the fibers of the Feixu are hollow and flexible. In this communication, three kinds of flexible Feixu fibers on the seeds of cynanchum, reed, and endive were used as matrix materials to synthesize conductive polyaniline (PANI) hollow composite fibers. Aniline was absorbed and polymerized on these natural materials forming flexible conductive composite fibers. The as-prepared PANI/Feixu composite fibers show good flexibility and conductivity.
