The homogeneity of the fibers in the production process of Nanofiber Membrane is crucial to the performance of the final product. The homogeneity of Nanofiber Membrane is not only related to the basic performance of the material, but also affects its practical performance in a variety of applications such as lithium batteries, filtration membranes, waterproof and breathable membranes, and biomedical materials.
Energy Battery Field
Nanofiber Membrane is often used as a diaphragm or electrode material. If the membrane thickness is not uniform, the impedance and current density inside the battery will be messed up, which directly affects the energy output and efficiency, and even affects the safety of the battery. Therefore, ensuring the uniformity of Nanofiber Membrane in microstructure is one of the keys to optimize battery performance.
In the field of filtration membranes, the high specific surface area of Electrospun Nanofbers has made them highly sought after among high-efficiency filtration materials. However, an uneven distribution of the fiber layer will drastically reduce the filtration efficiency, as well as increase the filtration pressure drop, leading to higher energy consumption and maintenance costs. Not only that, the non-uniformity of the membrane can cause overfiltration or underfiltration in localized areas, affecting the overall filtration effect.
In the field of biomedical materials, Nanofiber Membrane is widely used in the construction of tissue engineering scaffolds. The homogeneity of the scaffold material directly affects its drug loading capacity and drug release rate. Uneven fiber distribution not only affects the diffusion effect of the drug in the tissue, but also may lead to inconsistency in the local tissue repair effect, affecting the therapeutic effect.
In fact, it is not difficult to ensure the high uniformity of the electrospun film, first of all, to ensure that the syringe pump liquid supply is uniform and stable, in addition, the nozzle and the collector is also the key to obtain uniform fiber.
