Hybridizing nanocarbons, such as carbon nanotubes (CNTs) or graphene, with an active material is a powerful strategy towards designing next‐generation functional materials for environmental and sustainable energy applications. While research on nanocomposites, created by dispersing the nanocarbon into polymer ceramic matrices, began almost immediately after popularization of CNTs graphene in 1991 2004, respectively, hybrids are relatively recent addition to family composite materials. In...
Abstract Crude oil and hydrocarbon fuel spills are a perennial threat to aquatic environments. Inexpensive sustainable sorbents needed mitigate the ecological harm of this pollution. To address need, study features low‐density polysulfide polymer that is prepared by direct reaction sulfur used cooking oils.
