Description
Summary:TPU nanofibers' properties are affected by various electrospinning parameters, such as solution concentration, applied voltage, flow rate and rotational speed. [...]29 sets of experiments were designed here by the efficient and low-cost response surface methodology (RSM). [...]TPU is lighter in weight compared to rubber and does not require the vulcanization process necessary for synthetic rubber, so the production process is shortened by 25%, energy consumption is reduced by 25 to 40%, and production efficiency is increased by 10 to 20 times [3]. [...]TPU is not only a high-performance, high-quality polymer material but also a friendly material, in line with the requirements of green development [ ]. [...]RSM can also be considered an effective method to systematically explore the effect of multiple electrospinning parameters on the micromor-phology and mechanical properties of TPU nanofibers, thus promoting the development and application of TPU nanomaterials. [...]electrospinning parameters with ideal nanofiber diameter and mechanical properties were obtained.
