TY - JOUR TI - MICRO-NANOFIBERS WITH HIERARCHICAL STRUCTURE BY BUBBFIL-SPINNING AU - Liu Peng AU - Cai Juan-Juan AU - Zhao Lei AU - He Ji-Huan JN - Thermal Science PY - 2015 VL - 19 IS - 4 SP - 1455 EP - 1456 PT - Article AB - Bubbfil spinning is used to fabricate micro/nanofibers with hierarchical structure. The wall of a polymer film is attenuated unevenly by a blowing air. The burst of the bubble results in film fragments with different thickness, as a result, different sizes of fibers are obtained.
