中文摘要	Single-walled carbon nanotubes (SWNTs) were homogeneously dispersed in the aqueous solution of poly(N-isopropylacrylamide-co-acrylic acid) (P(NIPAm-co-AA)) with the assistance of sonification as evidenced by UV–vis absorption spectroscopy, transmission electron microscopy, field emission scanning electron microscopy and atomic force microscopy, etc. In addition, the SWNTs were endowed with pH and thermo-sensitivity at the same time. The SWNTs switched reversibly between the aggregated and the well-exfoliated states by using pH or temperature as a stimulus. Moreover, the factors including solvent composition while preparing P(NIPAm-co-AA), concentration and composition of P(NIPAm-co-AA) showed evident influence on the dispersing stability of SWNTs. The introduction of a tiny amount of acrylic acid to copolymerize with N-isopropylacrylamide could greatly enhance dispersing ability of SWNTs.
