Beschreibung
Zusammenfassung:	The invention provides a double-layer composite nanofiber membrane with a photothermal conversion function and a preparation method of the double-layer composite nanofiber membrane. The double-layer composite nanofiber membrane is formed by mutually compounding a self-floating polymer fiber layer and a composite nanofiber layer. The composite nanofiber layer comprises a thermoplastic polymer nanofiber membrane with a three-dimensional porous structure and photo-thermal nanoparticles, wherein the thermoplastic polymer nanofiber membrane is formed by mutually staggering thermoplastic polymer nanofibers after cross-linking reaction, and the photo-thermal nanoparticles are completely coated in the thermoplastic polymer nanofibers. The double-layer composite nanofiber membrane has good self-floating performance, excellent mechanical performance, high water delivery rate and excellent photothermal conversion performance. According to the preparation method, the integrated photo-thermal composite nanofiber is prepar
