Towards three-dimensional, multi-functional graphene-based nanocomposite aerogels by hydrophobicity-driven absorption

Abstract

By skillfully taking advantage of the high oil-absorption capacity of hydrophobic graphene aerogels (GAs), a novel, facile, scalable, and versatile approach is put forward for the preparation of three-dimensional, multi-functional graphene-based nanocomposite aerogels. Through the simple hydrophobicity-driven absorption of organic solutions containing functional modifiers, high-strength GA/polymer and magnetic GA/metal oxide aerogels were obtained.
