This disclosure describes hydrophobic or super-hydrophobic compositions, such as sponges, that also are oleophilic or super-oleophilic with superior recyclability, good mechanical strength, low cost, and manufacture scalability. The hydrophobic or super-hydrophobic compositions include the reaction product of at least a substrate having a reacting group which reacts with a silane and an alkylsilane or a fluoroalkylsilane having an alkyl group comprised of a hydrocarbon, an aliphatic hydrocarbon, or a fluorohydrocarbon of 1 to about 30 carbon atoms. |
