Abstract Hybrid supramolecular hydrogels embedded with carboxyl-functionalized carbon nanotubes (CNTs-COOH) were obtained via physical cross-linking. Transmission electron microscopy (TEM) were used to observe the microstructure of the sample. The effect of the introduction of the CNTs-COOH on the swelling behavior, gel-sol transition temperature and mechanical property of the gel were detected. The results revealed that compared with the initial gel, the inclusion of the carbon nanotubes(2.5wt.%)had no impacts on the morphology and microstructure of the gel, but caused an increase of its gel-sol transition temperature, also an ob-vious enhancement of the mechanical properties of the hybrid hydrogels. In addition, the hybrid hydrogel still retained the basic cha-racteristics of the supramolecular hydrogel, especially the characteristics of shear thinning, temperature sensitivity and spontaneous recovery.

Key words： supramolecular polymer carbon nanotube hydrogel self-assembly stability swelling property gel-sol transition temperature rheological property
