Abstract Oil spills and oil/water wastewater are among the great concerns
regarding oil pollution. Existing technologies face many limitations and in some
cases are responsible for causing secondary pollution, therefore there is as seek for
environmental friendly solutions. Biomass, from which celluloses are highlighted,
are being employed for oil/water separation or oil absorbents membranes.
Usually, these membranes are obtained by freeze drying of CNF (cellulose nano-
fibrils) suspensions followed by chemical modification for hydrophobization,
which involves expensive process as chemical vapor deposition and expensive
reactants as sylanes, turning these processes hardly scalable. Here, we produced
a natural porous structure paper from… More >
