The directional migration of SiO2 particles enhances the multiple scattering effect: New insights for improving the performance of light-scattering materials
Source abstract
Abstract
Abstract Regulating the selective distribution of functional fillers in polymer blends is an effective way to improve the properties of materials. In this paper, the directional migration and selective distribution of SiO2 particles within polycarbonate (PC)/poly (styrene-co-acrylonitrile) (SAN) microparts were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM), which are correlated with the multiple scattering effect and the light-scattering performance. Compared with the undirected migration, when SiO2 (2.00 × 10−2 g/cm3) migrated into the SAN phase, the scattering angle of the composites increased by 22.75%, and the scattering patterns and scattering surfaces also improved significantly. We believe that the multiple scattering of SiO2 particles greatly improved the scattering ability of the material under the limited volume of the SAN phase, which can provide new methods and ideas for the preparation of light-scattering materials with comprehensive performance.
