ABSTRACTUsing dissipative particle dynamics approach, we model phase separation in a ternary system encompassing cross-linked polyacrylamide (PAM) gel, oil and water. PAM gels are widely used in many applications, from food and cosmetic applications to enhanced oil recovery approaches. We show that the PAM nanogel adsorbs at the oil-water interface and spreads out over this interface for the case of a loosely cross-linked polymer network. Tailoring PAM behavior at the oil-water interfaces by controlling gel’s properties could allow one to alter the properties of oil-water emulsions.

The behavior of run-and-tumble nanoswimmers which can self-propel in two immiscible liquids such as water–oil systems and are able to cross the interface is investigated by dissipative particle dynamics.
