Abstract

Smooth azopolymeric microspheres were first synthesized by means of a microfluidic technique to yield high size uniformity. Both the monodisperse size and smooth surface of the azopolymeric microspheres enabled researchers to deterministically texture various surface relief gratings (SRGs) onto the curved surfaces. These characteristics also allowed systematic study of the optical phenomena, by means of both experimental and theoretical methods. A glass capillary microfl uidic device was used to generate monodisperse and highly smooth azopolymeric microspheres.
