Preparation of cross-linking multi-walled carbon nanotubes incorporated polymer via “click” chemistry |
| 초록 |
Chemical cross-linking of polymer incorporated multi-walled carbon nanotubes was prepared by azide–alkyne cycloaddition click chemistry. Firstly, block copolymer of poly(styrene-alt-maleic anhydride) (PSMA) were prepared by the reversible addition-fragmentation chain transfer (RAFT) polymerization. The highly reactive anhydride units were functionalized with furfuryl amine and propargyl amine in a one-pot reaction affording alkyne-furan bifunctional PSMA block copolymer (PSAF). The PSAF chains were covalently anchored to the surface of MWNTs affording PSAF/MWNTs by the Diels-Alder reaction in water under ultrasound assistance. Then, azide–alkyne cycloaddition click reaction took place between the PSAF/MWNTs and bis-(azidoethyl)disulfide as a crosslinking agent in the presence of Cu(0) wire/PMDETA. The obtained hybrid materials were characterized by TGA, FT-IR, Raman spectroscopy, and TEM analysis. The cross-linked PSAF/MWNTs could well enhance electrical conductivity. |
