Technical Field

The invention relates to the technical field of nanofiber membranes, in particular to a nanofiber membrane thickness measuring device.

Background

The nanofiber is widely applied to various fields such as filtration, noise reduction, sensors, protective clothing, drug controlled release, biological scaffolds, flexible electronics, new energy and the like by virtue of excellent mechanical, optical and electrical properties of the nanofiber, and the key of industrial application is to realize batch manufacturing of the nanofiber. At present, batch electrospinning technologies capable of manufacturing nanofibers in a large scale mainly include drum electrospinning, centrifugal electrospinning and the like, wherein czech researchers develop "nano-spider" devices by using the drum electrospinning technology and successfully realize commercialization. The thickness uniformity of the electrospun nanofiber membrane is an important index of the nanofiber membrane, and therefore, the online measurement of the thickness of the nanofiber membrane becomes an important link in the electrospinning manufacturing process of the fiber membrane.

Since the diameter (nanometer scale) of the fiber is generally smaller than the wavelength of light (submicron scale), the fiber cannot be detected by an optical measurement method, while the method of electron microscope (SEM) needs to be detected under a very high vacuum degree, has a slow speed and is not suitable for online detection in the batch production and manufacturing process of the nanofiber.

Therefore, we propose a nanofiber membrane thickness measuring device.
