Oil-in-Water Pickering Emulsions Stabilized by Halloysite Clay Nanotubes Toward Efficient Filterability

Unmodified natural clay particles, halloysite nanotubes (HNTs; l = 800 nm, douter = 50 nm, dinner = 15 nm), are used to stabilize oil-in-water Pickering emulsions (PEs). The hydrophilic HNTs are la...
