Superhydrophobic and superoleophilic cotton was fabricated.
The PDMS-coated cotton had an oil absorption capacity of up
7080 wt.%, oil selectivity of >99.15% after 500 cycles, good recyclability,
and robust mechanical stability. The loading capacity of the
PDMS-coated cotton was directly related to its oil absorption capacity.
These findings will assist with the development and application
of porous materials in oil/water separation
