Abstract
Oil spillages and industrial effluents have caused serious damage to the global environment. However, there are key challenges that remain in terms of expensive production costs, complex production methods, and environmental unfriendliness. In the present work, we developed a facile and efficient method to fabricate resilient hydrophobic cellulose-based foam via glyoxal cross-linking strategy and chemical vapor deposition to form MTMs coatings. The resulting foam exhibits excellent resilience (99%), ultra-low density (16.5 mg/cm3), high porosity (98.9%), high hydrophobicity (145.9°), good oil absorption (30 g/g-46.6 g/g). The above-mentioned advantages make cellulose-based foams promising materials for cleaning oil spills and oil–water separation.
