摘　　要：A novel photosensitive copolymer P（SS-co-AA-g-GMA）（PSAG） was synthesized and utilized to noncovalently functionalize pristine single-walled carbon nanotubes（SCNTs）. PSAG was highly effective for the solubilization of SCNTs in water and validated by UV-vis absorption spectra experiments, resulting in homogeneous and stable PSAG-SCNT aqueous dispersion. The microstructure of SCNTs was observed through Raman spectroscopy and transmission electron microscopy. In addition, compared with the two common polymeric dispersants of Triton X-100 and PSS, PSAG demonstrated more effective performances for dispersing SCNTs under identical conditions. Furthermore, the photosensitive PSAG-SCNTs can be crosslinked after UV irradiation, leading to significant improvement in the water resistance of SCNT films. UV-cured films can be transferred to plastic wrap to form a flexible film with high electrical conductivity.A novel photosensitive copolymer P（SS-co-AA-g-GMA）（PSAG） was synthesized and utilized to noncovalently functionalize pristine single-walled carbon nanotubes（SCNTs）.
