Preparation of bagworm silk/polyaniline composite

Abstract

Bagworm silk (BS) is the strongest natural fiber as known. We present the development of a bagworm‐based conducting synthetic/natural fiber composite for creating a flexible and strong textile. Fourier‐transform infrared spectroscopy, reflection UV–vis spectroscopy, scanning electron microscopy, electron spin resonance, and a superconducting quantum interference device (SQUID) were used to evaluate the composite. BS/PANI sheet resistivity was 1.0 × 102 kΩ/cm. The electrical conductivity measurements and magnetic measurements evaluated that the charge carriers of the composite were radical cations (polarons) of polyaniline.
