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

Abstract

Abstract 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.
