Abstract: (1570 Views)
Since the last two decades, polymeric nanocapsules have gained extensive interests and they have been widely used in various scientific fields. Although many studies have been performed on theoretical and experimental investigations of nanoencapsulation characterization so far, no study has been reported to measure the dye loading efficiency in a dye-doped liquid crystal (DDLC) mixture nanoencapsulated inside the core of polymeric nanocapsules because it’s impossible to evaluate the loading efficiency of dyes with low concentration using routine weight-based methods. In this work loading efficiencies of the liquid crystal and azo disperse dyes inside the core of fabricated polymeric nanocapsules were measured separately by using a comparative all spectroscopic analysis.
