Enhanced piezoelectricity from highly polarizable oriented amorphous fractions in biaxially oriented poly(vinylidene fluoride) with pure β crystals

Nature Communications, 2021
Piezoelectric polymers usually have rather low piezoelectric coefficients less than 30 pC/N. Here, the authors achieve a highly piezoelectric polymer (d 33 = −62 pC/N) based on a poled biaxially oriented poly(vinylidene fluoride) with a pure β phase due ...

On blends of poly(vinylidene fluoride) and poly(vinyl fluoride)

Macromolecules, 1986
Experimental evidence indicating immiscibility of the homopolymers poly(vinylidene fluoride) and poly(vinyl fluoride), both in the crystalline and amorphous phases, is presented. The X-ray analysis of the blended samples reveals patterns that are relatively insensitive to blend composition and that are similar to those found in previous studies ...
