Cu nanowires are important class of one dimensional metal nanowires with high electrical conductivity comparable to silver nanowires. Sophorolipid (SL), a well-known biosurfactant and glycolipid, plays significant role in the synthesis of nanomaterials as reducing and capping agent. Herein, we report the synthesis of Cu nanowires using sophorolipid by alkyl amine mediated hydrothermal synthesis and in this process, octadecylamine (ODA) used as alkyl amine. Cu nanowires of length ∼5−40μm and width ∼50−250 nm are produced at SL/ODA weight ratio of 0.13:1. Further structural investigations suggest that the morphology of these Cu nanostructures changes from nanowires to micron size rods and decahedron particles by modulating the weight ratio of SL and ODA.
