제목 Controlling the Location of Thermally-Stable Au Nanoparticles with Tuned Surface Property within Block Copolymers and Homopolymer Blends
초록 Polymer/nanoparticle hybrid materials have been investigated for many years due to their captivative properties. To control the dispersion of inorganic nanoparticles within polymer matrix, thiol-terminated polymers have been often used as a ligand to tune surface property of the nanoparticle. However, the interaction between the thiol group and metal is precarious with increasing temperature. To obtain the thermally-stable Au nanoparticles with precisely tuned surface property, we designed various UV-crosslinkable polymer ligands, which have different compositions of polar, UV-crosslinkable azide unit comparing to non-polar styrene units. After crosslinking the Au nanoparticles, it was found that the nanoparticles have superb stability at high temperature. Also we observed the location of the Au nanoparticles were well controlled within the polymer matrixes, such as hopolymer blends or block copolymers.
