Modular ambient temperature functionalization of carbon nanotubes with stimuli-responsive polymer strands
Abstract
Cyclopentadienyl end-capped poly(N-isopropylacrylamide) (PNIPAM-Cp, M n = 5400 g mol-1, PDI = 1.13) was synthesized via a combination of RAFT (Reversible Addition-Fragmentation Chain Transfer) polymerization and modular conjugation (characterized via Nuclear Magnetic Resonance (NMR) as well as Electrospray Ionization-Mass Spectrometry (ESI-MS)), and reacted with untreated Single Walled Carbon Nanotubes (SWCNTs) as dienophiles in a Diels-Alder reaction with PNIPAM-Cp (diene) at ambient temperature in the absence of any catalyst. The obtained stimuli-responsive hybrid materials display thermo-responsive behaviour evidenced via UV-VIS-spectroscopy and Dynamic Light Scattering (DLS). The grafting density of the PNIPAM chains at the surface of the SWCNTs was determined via Thermogravimetric Analysis (TGA), Elemental Analysis (EA) and X-ray Photoelectron Spectroscopy (XPS), to be close to 0.0288 chains per nm 2. © 2013 The Royal Society of Chemistry.
