Thermosensitive Nanocables Prepared by Surface-Initiated Atom Transfer Radical Polymerization

Thermosensitive Nanocables Prepared by Surface-Initiated Atom Transfer Radical Polymerization

<p>Abstract</p> <p>Thermosensitive nanocables consisting of Au nanowire cores and poly(<it>N</it>-isopropylacrylamide) sheaths (denoted as Au/PNIPAAm) were synthesized by surface-initiated atom transfer radical polymerization (SI-ATRP). The formation of PNIPAAm sheath w...
