Abstract

A new and facile method to obtain polymeric nanodroplets was developed by thermally annealing of electrospun fibers of immiscible polymer blends. Through thermally annealing at a temperature slightly above the glass transition temperature of the matrix, the ribbon- or fiber-like dispersed phase broke up into nanodroplet with the diameter mainly in the range of 50–300 nm due to the Plateau-Rayleigh instability. Our study shows that these nanodroplets can be used to study the fractionated crystallization and homogeneous nucleation of almost any semicrystalline polymers, such as poly(ethylene oxide), poly(vinylidene fluoride), polyethylene, and polypropylene. We observed that the homogeneously nucleated crystallization of PVDF took place at 55–60°C for the first time. Additionally, this method can be utilized to investigate the effect of nanoconfinement on crystalline morphologies of semicrystalline polymers.
