Water-assisted fabrication of porous bead-on-string fibers

We use the Rayleigh instability technique and breath figure method to fabricate porous bead-on-string fibers and regulate the size and distribution of the pores by controlling the resin reaction conditions. Interestingly, a variety of bead-on-string fibers , with smooth, less porous, homogenous porous, gradient porous and dented microstructures could be easily prepared.
