Abstract
This disclosure is related to a class of metal-ion induced hydrophobic polymers and method of producing such class of compounds by a one-step solution immersion process. Specifically, a metal-ion Induced hydrophobic polymer or melamine sponge (MII-HMS) is disclosed. Such polymer or sponge is demonstrated to be highly hydrophobic and oleophilic and exhibits excellent oil absorption capabilities, being able to absorb a wide range of oils and organic solvents up to 71 to 157 times of its own weight.
