S-coated-MWCNTs

Coating sulfur onto the surface of different carbon materials improves the dispersion of sulfur on the composite materials. The S-coated-MWCNTs are prepared through capillarity behavior between liquid sulfur and MWCNTs. With a low surface tension of 61 mN m, hquid sulfur wets and fills carbon nanotubes...
