Nanoclay-Directed Structure and Morphology in PVDF Electrospun Membranes

Abstract EN

The incorporation of organically modified Lucentite nanoclay dramatically modifies the structure and morphology of the PVDF electrospun fibers.

In a molecular level, the nanoclay preferentially stabilizes the all-trans conformation of the polymer chain, promoting an α to β transformation of the crystalline phase.

The piezoelectric properties of the β-phase carry great promise for energy harvest applications.

At a larger scale, the nanoclay facilitates the formation of highly uniform, bead-free fibers.

Such an effect can be attributed to the enhanced conductivity and viscoelasticity of the PVDF-clay suspension.

The homogenous distribution of the directionally aligned nanoclays imparts advanced mechanical properties to the nanofibers.
