제목 Controlling the Dispersity and Location of Gold Nanoparticles within Polymer Matrix by Varying Composition and Length of Ligands
초록 Nanocomposites have been investigated for many years due to their fascinating features. In spite of the captivative properties, compatibility problem has been an obstacle for manufacturing the nanocomposites. To achieve the compatibility between NPs and polymer matrix, thiol-terminated polymeric ligands have been used for tuning the surface property of the NPs. However, in case of Au NPs, Au-thiol bond is unstable above 60 °C. In our recent work, we designed thermally stable Au NPs by using thiol terminated photo crosslinkable block copolymer. Herein, we prepared thermally stable Au NPs using photo crosslinkable polymeric ligands that have various ligand composition and lengths. As the ligands characteristics were changed, the phase behaviors of Au NPs in both homopolymer and block copolymer bulk sample were significantly different. In this work, morphologies of Au NPs within polymer matrix were systematically investigated using the cross-sectional transmission electron microscopy.
