| titleOfInvention | Palygorskite-double-network gel sponge with oil repellency and water absorption functions as well as preparation method and application thereof |
| abstract | The invention discloses an oil-repellent water-absorbent palygorskite-double-network gel sponge, a preparation method and application thereof, wherein polyacrylamide hydrochloride solution and palygorskite dispersion liquid are mixed and centrifugally dried to obtain polyacrylamide modified palygorskite powder; uniformly dispersing polyacrylamide modified palygorskite powder in water to obtain polyacrylamide modified palygorskite dispersion liquid; mixing and reacting the polyacrylamide modified palygorskite dispersion liquid with a sodium perfluorooctanoate solution, and performing centrifugal drying treatment to obtain modified palygorskite powder; uniformly dispersing modified palygorskite powder in water to obtain modified palygorskite dispersion liquid; adding acrylamide and sodium alginate into the modified palygorskite dispersion liquid, dissolving, adding potassium persulfate and N, N' -methylene bisacrylamide, dissolving, adding tetramethylethylenediamine, and stirring until the solution is converted into gel; and (3) soaking the gel in a calcium chloride solution, and performing freeze drying treatment to obtain the palygorskite-double-network gel sponge. The invention can realize the purification treatment of oil substances. |
