‘‘Click’’ Synthesis of Thermally Stable Au Nanoparticles with Highly Grafted Polymer Shell and Control of Their Behavior in Polymer Matrix |
| 초록 |
Thermally stable coreshell Au NPs with highly grafted polymer shells were synthesized by combining RAFT polymerization and click chemistry of CuAAC. First, alkyne-terminated poly(4-benzylchloride-b-styrene) (alkyne-PSCl-b-PS) was prepared from the alkyne-terminated RAFT agent. Then, an alkyne-PSCl-b-PS chain was coupled to azide-functionalized Au NPs via the CuAAC reaction. Careful characterization showed that PSCl-b-PS chains were successfully grafted onto the Au NP surface with high grafting density. Finally, azide groups were introduced to PSCl-b-PS chains on the Au NP surface to produce thermally stable Au NPs with crosslinkable polymer shell (Au-PSN3-b-PS 1). As the control sample, PS-b-PSN3-coated Au NPs (Au-PSN3-b-PS 2) were made by the conventional ‘‘grafting to’’ approach. The grafting density of polymer chains on Au-PSN3-b-PS 1 was found to be much higher than that on Au-PSN3-b-PS 2. |
