TLDR
In this paper, the authors found that milkweed fiber and cotton fiber sorbed significantly higher amounts of crude oil than polypropylene fiber and polyethylene web from the surface of an artificial sea water bath containing crude oil and from a crude oil bath.Abstract:
Milkweed (Asclepias) fiber and cotton fiber sorbed significantly higher amounts of crude oil than polypropylene fiber and polypropylene web from the surface of an artificial sea water bath containing crude oil and from a crude oil bath. Milkweed sorbed approximately 40 g of crude oil/g of fiber at room temperature. The oil sorption capacity of kenaf core material was comparable with that of polypropylene web with high-viscosity Bunker C oil. Only a slight variation was observed in the oil sorption of the natural fiber sorbent by Soxhlet extraction and water-soaking treatments before the sorption processread more

Hydrophobic nanocellulose aerogels as floating, sustainable, reusable, and recyclable oil absorbents.
TL;DR: By functionalizing the native cellulose nanofibrils of the aerogel with a hydrophobic but oleophilic coating, such as titanium dioxide, a selectively oil-absorbing material capable of floating on water is achieved.
