Preparation of PVDF with High β-phase for Intelligent Fabrics

Flexible polyvinylidene fluoride (PVDF) has excellent piezoelectric properties, it has broad application prospects in wearable electronic products and smart fabrics. PVDF fibers or films with high phase can be obtained by solution casting, electrospinning, stretching and other preparation methods, but they cannot meet the complex shape requirements of wearable products. The PVDF piezoelectric fibers and films prepared by near-electric field 3D printing method not only have high -phase content, but also do not need to undergo polarization, especially for customized preparation. This provides a new idea for fabricating wearable flexible devices based on intelligent fabrics.
