| titleOfInvention | Formaldehyde purification fiber and preparation method thereof |
| abstract | The invention provides a preparation method of formaldehyde purification fiber, which comprises the steps of dissolving a polymer in an organic solvent to prepare a spinning solution, and obtaining polymer fiber after electrostatic spinning and vacuum drying, wherein the polymer comprises at least one of polymethyl methacrylate, polyacrylonitrile and polyvinylidene fluoride; providing noble metal nano particles and uniformly dispersing the noble metal nano particles in absolute ethyl alcohol to obtain a mixed solution; and (3) soaking the polymer fiber in the mixed solution, taking out, washing, and drying in vacuum to obtain the formaldehyde purification fiber. The preparation method is simple, the preparation process is environment-friendly and pollution-free, the polymer fiber is not required to be treated, the process flow is reduced, the time is saved, the cost is low, and the industrial production is facilitated; the prepared formaldehyde purification fiber has excellent formaldehyde removal effect and wide application prospect in the aspect of removing formaldehyde. |
