Dispersion of multiwalled carbon nanotubes in aqueous silk fibroin solutions

A simple method was developed to densely assemble multiwalled carbon nanotubes (MWCNTs) onto single native spider silk and silkworm silk fibers in aqueous system. The interactions between the MWCNTs and the silk fibroin were investigated using scanning electron microscopy and transmission electron microscopy. Furthermore, the role of pure silk fibroin in dispersing MWCNTs in aqueous systems was also assessed.
