| 英文摘要 | A well-dispersed gold nanoparticle-poly-n-isopropylacrylamide (pnipam) hydrogel composite with thermo-switchable electrical properties was prepared by the co-polymerization of au nanoparticles with attached vinyl groups with nipam. the an nanoparticles and the composite are characterized by tem, uv-vis, ftir, and nmr. at the same time. the electrical conductivity, cyclic voltammetry and constant-pontential technique were used to demonstrate the electrical properties of the composite. it was found that the electrical properties of the composite show a tunable property with changing temperature and the electrical conductivity changes by two orders of magnitude at the transition temperature (t-tran). the t-tran of the composite can be adjusted from 0 degrees c to 40 degrees c by changing the concentration of au nanoparticles, the degree of cross-linking or the composition of composite. the change in electrical properties is reversible in a heating and cooling cycle. |
