제목 Synthesis of Optically Enhanced Polymer Nanocomposites: Integration of Inorganic-Ligands-Exchanged ZnS Nanocrystals into an Amorphous Polymer Matrix
초록 Colloidal syntehsis can provide organically-capped nanocrystals with long chains, which enable for NCs to stabilize in a nonpolar solvent, however, having various infrared peaks in the fingerprint region. Inorganic surface ligands with short chains, on the other hand, exhibit a stability in a polar solvent and more optically transparent property due to the less IR peaks in the region of interest in general. Herein, organic capping ZnS NCs were modified with inorganic ligands so that NCs can functionalize in a specific polymer system where the as-synthesized NCs do not work, resulting in a successful distribution of ZnS NCs into an amorphous polymer matrix. The synthesized polymer nanocomposites characterize in an enhanced high refractive index due to the integration of ZnS. As well, the increase of IR-transmittance can be accomplished by replacing the the organic polymer volume into the inorganic surface ligands.
