Description

technical field [0001] The invention belongs to the field of electrospinning and relates to a device for collecting electrospun fiber samples in a constant humidity and constant temperature environment. Background technique [0002] Electrospinning technology is widely used in the field of nanofiber material preparation. Due to its excellent physical and chemical properties, nanofiber materials have a wide range of application fields and unlimited development prospects. Countries are stepping up to improve the existing electrospinning technology or develop new electrospinning equipment. In the process of electrospinning, the charged polymer solution is sprayed, stretched, split, volatilized and solidified in a high-voltage electrostatic field to finally form fibrous properties. There are many parameters that affect the morphology and properties of electrospun fibers, such as the voltage provided by the high-voltage power supply, the distance between the collecting plate and...
