Electronic textiles offer electrical functionality and flexibility, making them promising materials for next-generation wearable devices. Bio-based fibers like silk and cotton, are gaining attention as sustainable alternatives. Silk stands out for its light weight, biocompatibility, and exceptional mechanical strength. On the other hand, carbon nanotubes (CNT) provide excellent electrical conductivity, thermal conductivity, lightweight, durable, and flexible. Thus, CNT/silk composite fibers have attracted considerable research interest. However, achieving high conductivity in CNT/silk composite fibers without compromising the intrinsic strength of silk remains a significant challenge. In this study, we address these challenges by fabricating CNT/silk composite fibers via a simple dip-and-dry method, with systematic optimization of silk degumming ratio to simultaneously enhance mechanical strength, electrical conductivity, and thermal conductivity.
