Study on Pickering emulsions co-stabilized by multiple particles for building MXene-based multifunctional composite foam

摘要

Pickering emulsion, an emulsion prepared by replacing conventional surfactants with solid particles, has been extensively used to construct a variety of functional materials especially 3D porous foams or aerogels. Ti3C2Tx MXene have recently garnered tremendous attention and considered as a promising candidate for the construction of functional nanomaterials due to their fascinating properties. However, it remains a challenge to construct MXene-based composite porous materials. Herein, the Pickering emulsion co-stabilized by multiple kinds of particles and the subsequent MXene-based multifunctional composite foam were studied. The formation mechanism of Pickering emulsions stabilized by cellulose nanofibrils (CNF), nickel nanowires (Ni NW), and Ti3C2Tx MXene was investigated along with their stabilization mechanism in a complex water-oil environment.
