“…The effects of electrospinning parameters on the crystallinity and β-phase content of PVDF membranes have been reported in published works [ 29 , 30 ]. Here, PVDF electrospun membranes (M3, M8–M10) with different voltages, feed rates, and distances were prepared, and we confirmed that the electrospinning parameters certainly influence the piezoelectric properties of PVDF membranes.…”

“…Many works [ 29 , 30 ] have focused on improving the piezoelectricity of PVDF nanofibrous membranes by controlling the electrospinning parameters. Gee et al [ 29 ] synthesized a set of membranes with systematically variable electrospinning parameters (the fraction between DMF and ACE, tip-to-collector distance (TCD), flow rate, and voltage setting), and they ranked parameters according to the contribution on the β-phase fraction: solvent > flow rate > TCD > voltage.…”

However, the connection among parameters and the relative contribution to the β-phase fraction was not investigated.…”

PVDF electrospun membranes were prepared by employing different mixtures of solvents and diverse electrospinning parameters. A comprehensive investigation was carried out, including morphology, nanofiber diameter, crystallinity, β-phase fraction, and piezoelectric response under external mechanical strain. It was demonstrated that by using low-toxicity DMSO as the solvent, PVDF membranes with good morphology (bead-free, smooth surface, and uniform nanofiber) can be obtained. All the fabricated membranes showed crystallinity and β-phase fraction above 48% and 80%, respectively; therefore, electrospinning is a good method for preparing PVDF membranes with the piezoelectric properties. Moreover, we considered a potential effect of the solvent properties and the electrospinning parameters on the final piezoelectric properties. When PVDF membranes with different β-phase fractions and crystallinity values are applied to make the piezoelectric transducers, various piezoelectric voltage outputs can be obtained. This paper provides an effective and efficient strategy for regulating the piezoelectric properties of PVDF electrospun membranes by controlling both solvent dipole moment and process parameters. To the best of our knowledge, this is the first time that the influence of a solvent’s dipole moment on the piezoelectric properties of electrospun materials has been reported.

Fish sarcoplasmic proteins (FSP) account for 20%–40% of the muscle protein and its high‐value utilization has become an urgent problem to be solved. Here, directly freeze‐dried sarcoplasmic protein (DFSP) and chitosan flocculated sarcoplasmic protein (CFSP) nanofibers were successfully fabricated by electrospinning technology and characterized in terms of morphology, chemical interaction, surface and mechanical properties, and thermal stability. SDS‐PAGE indicated similar protein bands for both DFSP and CFSP. Scanning electron microscopy observation showed good spinnability for CFSP and DFSP. Fourier transform infrared spectrometry and X‐ray diffraction results unveiled an interaction between sarcoplasmic protein and chitosan in CFSP nannofiber. Furthermore, CFSP nanofiber exhibited better performance than DFSP nanofiber in surface hydrophobicity, thermal stability, elasticity and flexibility. These results suggest the potential application of FSP nanofiber in functional components or drugs delivery, contributing to high‐value utilization of FSP.

Poly(vinylidene fluoride) (PVDF)‐based polymers demonstrate great potential for applications in flexible and wearable electronics but show low piezoelectric coefficients (e.g., −d33 < 30 pC N−1). The effective improvement for the piezoelectricity of PVDF is achieved by manipulating its semicrystalline structures. However, there is still a debate about which component is the primary contributor to piezoelectricity. Therefore, current methods to improve the piezoelectricity of PVDF can be classified into modulations of the amorphous phase, the crystalline region, and the crystalline–amorphous interface. Here, the basic principles and measurements of piezoelectric coefficients for soft polymers are first discussed. Then, three different categories of structural modulations are reviewed. In each category, the physical understanding and strategies to improve the piezoelectric performance of PVDF are discussed. In particular, the crucial role of the oriented amorphous fraction at the crystalline–amorphous interface in determining the piezoelectricity of PVDF is emphasized. At last, the future development of high performance piezoelectric polymers is outlooked.
