電紡絲技術是基於高壓靜電場下導電流體產生高速噴射的原理發展而來,其基本過程是:聚合物溶液或熔體在幾千至幾萬伏的高壓靜電場下克服表面張力而產生帶電噴射流,溶液或熔體射流在噴射過程中乾燥、固化,並保持一定電荷量,最終落在接收裝置上形成纖維氈或其它形狀的纖維結構物。The neutral gas pressure is smaller where electric fields is stronger, which is independent of the instantanious electric polarity of the electrode and cause gas flow from high pressure region to low pressure region. so flow can be accelerated if electric field is properly adjusted, which is the mechanism of the active flow control
