FTIR spectrum of perfluoropolyether tetraacrylate, . The molecular structure of is also shown.
(a) Photograph of a replicated nipple array on a size glass substrate illuminated with white light. (b) AFM image of a nipple array with height. (c) Experimental (solid) and simulated (dotted) specular optical reflectivity at normal incidence. Black: flat glass substrate. Orange: nonfluorinated polymer (PETPTA) nipple array with height. Red: nipple array with height. Blue: hemispherical nipple array with height. All samples are templated from diameter silica spheres.
Simulated specular reflectivity at normal incidence for nipple arrays templated from silica particles with diameters ranging from .
(a) Scanning electron microscope (SEM) image of an ordered colloidal monolayer template. Inset showing Fourier transform of the image. (b) SEM image of a disordered template with the same particle number density as (a). Inset showing Fourier transform of the image. (c) Comparison of the measured normal-incidence specular reflectivity between disordered and ordered nipples with the same size, height, and number density.
