The traditional emulsification theory is enriched by a self-assembly approach, in which hydrophilic copolymers with one block exhibiting electrostatic or hydrogen-bonding forces with the oil phase self-assemble at the oil–water interface, thereby reducing interfacial tension and forming emulsions.

AbstractThe influence of density of amino groups, nanoparticles dimension and pH on the interaction between end-functionalized polymers and nanoparticles was extensively investigated in this study. PS–NH2 and H2N–PS–NH2 were prepared using reversible addition–fragmentation chain transfer polymerization and atom transfer radical polymerization. Zero-dimensional carbon dots with sulfonate groups, one-dimensional cellulose nanocrystals with sulfate groups and two-dimensional graphene with sulfonate groups in the aqueous phase were added into the toluene phase containing the aminated PS. The results indicate that aminated PS exhibited the strongest interfacial activity after compounding with sulfonated nanoparticles at a pH of 3. PS ended with two amino groups performed better in reducing the water/toluene interfacial tension than PS ended with only one amino group. The dimension of sulfonated nanoparticles also contributed significantly to the reduction in the water/toluene interfacial tension. The minimal interfacial tension was 4.49 mN/m after compounding PS–NH2 with sulfonated zero-dimensional carbon dots.

Manipulation of the charge of the dielectric interface between two bulk liquids not only enables the adjustment of the interfacial tension, but also controls the storage capacity of ions in the ionic double layers adjacent to each side of the interface.

A lotus leaf inspired Janus hybrid film was exquisitely fabricated through a self-assembly process on the water/air interface with subsequent in situ asymmetric modification at the oil/water interface. The interfacial asymmetric decoration strategy thus provides a novel pathway for achieving a 2D Janus hybrid film with asymmetric wettability and functionality.
