- •
Mechanism of oil detachment from a glass surface in water is studied by molecular dynamics simulation.
- •
The process of glass cleaning in water can be divided into three stages and the formation of different water channels in the oil phase is vital for the oil detachment.
- •
The specific ring potential well structure of amorphous silica surface will hinder the detachment of oil.
- •
One of the effective ways to clean up the oil pollution residues on the glass surface is increasing the upward lift force which acts on the hydrocarbon tail of oil molecules.
