Perfluorinated polymer colloids: Controlling the size, shape, and surface charge

► First account of perfluorocyclobutyl (PFCB) aryl ether polymer colloids. ► Size of perfluorinated polymer colloids controlled by concentration. ► Surface charge of colloids modified by post-functionalized sulfonic acid groups. ► Different self-assembly morphologies were observed on four different substrates; spherical (Al), clover-like (Cr), flower-like (C), and “squalloid” (Si).
