Characterization of silica/PET antiglare films using image analysis and dynamic dispersity index

Abstract

This article proposes an advanced theoretical framework that quantitatively evaluates dispersion state of silica beads of a PET-based antiglare film. The positional randomness of bead dispersion is expressed via a single scalar value, the dynamic dispersity index. The static dispersity index definition based on molecular dynamics, which was proposed in our previous work, was improved with a pseudo-relaxation algorithm. PET-based antiglare films, which had the variable degree of particle dispersion, were used for the verification together with graphically drawn artificial bead images. © 2013 Wiley Periodicals, Inc.
