Facile synthesis and characterization of polymer embedded catenated nanosulfur

The study deals with the facile synthesis of catenated nanosulfur by entrapping elemental sulfur with polyethylene glycol 400 with the help of bottom up approach. The synthesized nanosulfur was studied by transmission electron microscope (TEM), x-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and thermogravimetric analysis (TGA). The average size was about 35.5 ± 8.5 nm which was confirmed by TEM distribution curve fitted with Gaussian model. XRD shows that the synthesized nanosulfur was crystalline in nature. FTIR study confirmed that PEG was encapsulated over catenated nanosulfur. TGA confirmed the stability of nanosulfur up to 200 °C as there was no significant change in the differential weight with respect to temperature 200 °C. The active ingredient of this encapsulated nanosulfur was 0.62 g/g which was estimated by UHPLC.
