Green Fabrication of a Multifunctional Sponge as an Absorbent for Highly Efficient and Ultrafast Oil-Water Separation.

ABSTRACT: Oil leakage results in serious environmental pollution and severe waste of resources, which makes the development of low-cost, environmentally friendly, high-capacity, and durable oil absorbents an urgent task. In this paper, superhydrophobic coatings of activated carbon (AC)-TiO₂-PDMS@PDMS were developed without using any fluorine-containing reagents. The TiO₂ particles were grown on the AC surface to form AC-TiO₂ powders. The hydrophilic AC-TiO₂ powders were further grafted with polydimethylsiloxane (PDMS) molecules (AC-TiO₂-PDMS) to achieve superhydrophobicity through covalent reaction between PDMS and TiO₂ under UV light. The AC-TiO₂-PDMS powder was mixed with a PDMS polymer to form a superhydrophobic coating
