外文摘要：To optimize the independent bubble electrospinning process and control the bubble stability and size, an improved approach, critical bubble spinning, for obtainingmass production of high-quality nanofibers was proposed. Continuous spinning behaviors could be achieved by the perturbations of the free surface from the polymer bubble film in airflow and electric fields, which became sites of jetting directed upward efficiently. Subsequently, the formation law of multiple jets and its mechanism were studied. As a result, the internal and external forces triggered the formation of daughter bubble cascades, so lower energy was needed for nanofiber fabrication. At last, the universality of critical bubble electrospinning was verified, and it should be noted that both high-quality organic and inorganic nanofibers could be obtained, indicating that innovation of critical bubble electrospinning was feasible for practical applications. ? 2020 by the authors.
