The invention relates to a preparation method of a composite color-changing nanofiber membrane, which is prepared by preparing a fiber membrane precursor from spinning stock solution containing composite color-changing capsules, water-based UV resin, a photoinitiator and polyvinyl alcohol through electrostatic spinning, and then carrying out photo-initiated polymerization. The preparation process is simple, the prepared nanofiber membrane has good mechanical strength and water resistance, has good visual correspondence to ultraviolet intensity and temperature change, has afterglow fluorescence in dark environment, has good color expression in bright and dark environments, and has wide application prospect. |
