Hierarchical polystyrene patterns produced by electrospinning

  title={Hierarchical polystyrene patterns produced by electrospinning},
  author={Yu Xin and Darrell H. Reneker},
Abstract When a 25 wt% polystyrene solution was electrospun at relatively low applied voltage, the bending instability initiated, grew and disappeared, repeatedly. Upon further lowering of the applied voltage, the bending instability died immediately after it started and only a straight electrified jet was observed. By manipulating the bending instability of the jet, uniform polystyrene hierarchical patterns were produced by a buckling process. The observed buckling patterns are similar to… CONTINUE READING
