| titleOfInvention | Nanosheet carbon nitride composite pH-sensitive hydrogel with Pizza structure, and preparation method and application thereof |
| abstract | The invention relates to a nano-sheet carbon nitride composite hydrogel with a Pizza structure, and a preparation method and application thereof. The invention directly polymerizes into a polyacrylic acid film (PAA) by irradiating acrylic acid solution under certain conditions in ultraviolet, nano-sheet carbon nitride (CNNS) with certain mass is bound on a substrate by taking the PAA as the substrate, and then the CNNS/PAA and acrylamide solution are irradiated by a xenon lamp under the filtration of a 420nm optical filter, so that the CNNS can initiate acrylamide to polymerize on the CNNS/PAA to generate the Pizza CNNS composite hydrogel with an interpenetrating network structure. The PAM/CNNS/PAA with the interpenetrating network structure is found to be greatly improved in tensile strength compared with PAA, the membrane morphology structure of the PAM/CNNS/PAA composite hydrogel is different from the agglomerate hydrogel structure of common organic polymeric materials and photocatalysis materials, the adsorption effect of PAM and PAA and the photodegradation effect of CNNS can be efficiently coordinated in the printing and dyeing wastewater treatment, and the problem that most photocatalysts are difficult to recover is solved. |
