Abstract
Summary: Thiol‐reactive‐functionality decorated multi‐walled carbon nanotubes (MWNTs) have been obtained. Trithiocarbonate‐ended poly(N‐(2‐hydroxypropyl)methacrylamide) (PHPMA) is prepared by reversible addition‐fragmentation chain transfer (RAFT) polymerization of N‐(2‐hydroxypropyl)methacrylamide (HPMA) using S‐1‐dodecyl‐S′‐(α,α′‐dimethyl‐α″‐acetic acid)trithiocarbonate as chain transfer agent, subsequently, thiol‐terminated PHPMA (PHPMA‐SH) is obtained by treating trithiocarbonate‐ended PHPMA with hexylamine. The PHPMA‐S‐S‐MWNT conjugate is formed by simply stirring the mixture of thiol‐reactive‐functionality decorated MWNTs with PHPMA‐SH in phosphate buffered saline by a thiol‐coupling reaction. FT‐IR, HRTEM, ^1^H NMR, and TGA results show that this thiol‐coupling reaction is effective to produce aqueous soluble polymer–MWNT conjugates under mild conditions.
Thiol‐reactive‐functionality decorated multi‐walled carbon nanotubes are modified with thiol end‐capped polymers by a thiol‐coupling reaction.
