Controllable Underwater Oil-Adhesion-Interface Films Assembled from Nonspherical Particles

A controllable underwater oil-adhesion-interface is presented based on colloidal crystals assembled from nonspherical latex particles. The underwater oil-adhesive force of the as-prepared film can be effectively controlled from high to low adhesion by varying the latex structures from spherical or cauliflower-like to single cavity, which effectively adjusts the solid/liquid contact mode/wetting state of oil droplets on the films. This facile fabrication of functional films with special underwater oil-adhesion properties based on a flexible design of a latex structure will offer significant insight for the design and creation of novel underwater antifouling materials.
