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.
