✦ Synopsis

Abstract

In this paper, we modified carbon nanotubes with the thiol‐reactive species, subsequently combined the thiol‐coupling reaction and reversible addition‐fragmentation chain transfer (RAFT) polymerization to prepare temperature‐responsive PNIPAAm (poly(N‐isopropylacrylamide))‐carbon nanotube conjugates. The prepared PNIPAAm‐carbon nanotube conjugates have temperature‐responsive PNIPAAm chain, and disulfide linkages between PNIPAAm and carbon nanotube which are sensitive to bio‐stimuli such as glutathione, therefore dual‐responsive polymer‐carbon nanotube conjugates have been prepared.

## Abstract **Summary:** Polyaniline composite film with nano‐structure was prepared through a chemical oxidation method by adding carbon nanotubes (CNTs) as nano‐fiber seeds. Spin‐coating or casting method was employed on the interdigital electrodes of carbon and the composite film was formed with
