Cystine modified nano-sulfur and its spectral properties

Abstract A novel sulfur form, insect-like nano elemental sulfur (nano-S0) was prepared by adding cystine to sulfur-ethanol solution. The modification and modulation of cystine on elemental sulfur (S0) nanoparticles in liquid phase were studied. Transmission electron microscope (TEM), resonance Rayleigh scattering (RRS), infrared (IR) and Raman spectra (RS) were used to study the function of cystine in modification and assembly of S0 nanoparticles. The results show that the cystine modulated the S0 nanoparticles in the aspects of the size, shape and stability in the liquid phase. The cystine-nano-S0 Sol obtained was stable in solution for long time.
