Electrospun organic piezoelectric nanofibers and their energy and bio applications

A Flexible Multifunctional PAN Piezoelectric Fiber with Hydrophobicity, Energy Storage, and Fluorescence

“…However, after the addition of Eu (NO 3 ) 3 ·6H 2 O and ILs, the strong interaction between them had a certain effect on the orientation of the composite fibers, and the orientation was not as obvious as that of the PAN-IL composite fibers. As the IL concentration increased, the electrostatic force stretching increased, the dipoles became more polarized, and more PAN piezoelectric phases (planar zigzag conformation) were induced to form [ 15 ]. As shown in Figure 3 , the bar graph represented the fiber diameter distribution, and the peak of the curve represented the average diameter.…”

“…Polyacrylonitrile (PAN) is a kind of piezoelectric polymer. PAN nanofibers prepared by electrospinning technology have the advantages of appropriate piezoelectric properties, good mechanical properties, and high piezoelectric sensitivity, which makes it widely used in the field of flexible piezoelectric sensors [ 15 ]. PAN is an amorphous vinyl-type polymer containing a cyano group (-CN) in each repeating unit [ 16 ].…”

Toward a new generation of permeable skin electronics

“…Efforts are underway to develop gas-permeable skin-mountable bioelectrical sensors. [181][182][183][184][185] One method is to fabricate electronic tattoos. 25,186 For example, a breathable electronic tattoo sensor was prepared using laser-induced hierarchical carbon nanofibres (LIHCNFs).…”

An electrospun cellulose-based nanofiber piezoelectric membrane with enhanced flexibility and pressure sensitivity

“…= 1 pC N −1 ). 18 Additionally, electrospinning of cellulose requires special equipment (for cellulose regeneration) and generally produces non-uniform and highly branched nanofibers. 19 Fortunately, cellulose derivatives exhibit higher piezoelectric constants.…”
