“…The work reported in this paper is aimed at complementing work done by three other groups [12,17,18] in addition to investigating the piezoelectric response of the PVDF/AgNPs electrospun mats. The first group [17] used 5 nm prepared AgNPs to enhance the antifouling properties of PVDF membranes and reported that the produced nanocomposite fibers became smoother and finer with addition of silver.…”

“…The preparation of the PVDF/AgNPs composite fiber mats was based on previously reported methods [17,18]. PVDF/AgNPs solutions were prepared as follows: 0.0525 g of AgNPs was mixed with 20 g of the 13% PVDF solution to prepare a 2% PVDF/AgNPs stock solution.…”

“…Shrivastava et al [16] reported that 25 μg·mL −1 will completely inhibit the bacteria, regardless of whether it is positive or negative, or it is antibiotic resistant or non-resistant. The AgNPs apparently attach to walls of the bacterial cells, penetrate them, and destroy the cell content, either as silver clusters or as silver ions [16,17].…”

Poly(vinylidene fluoride) (PVDF) is a piezoelectric material with outstanding physical and mechanical properties. The piezoelectric properties depend on the β-phase content of this polymer, while the physical and mechanical properties depend on the morphology and degree of crystallinity of the material. Silver has antibacterial effects, and silver nanoparticles (Ag-NPs) have large surface areas rich in electrons. In this paper, we produced electrospun PVDF fibrous mats that contained different contents of Ag-NPs between 0% and 1.0%. The β-content in PVDF was found to increase by about 8% for Ag-NPs content of 0.4-0.6%. The electrospun fiber mats had a higher β-crystalline content, nano-pores were visible on the fiber surfaces, and the tensile strength and thermal stability were improved. Dielectric analysis indicated weak interfacial adhesion between the PVDF and AgNPs. Good piezoelectric response was observed in the electrospun fibers containing 0.4% AgNPs, which shows a good correlation between the β-crystalline phase content of the composites and its energy-harvesting application.

“…the coaxial electrospinning provides a versatile method to encapsulate immobilized antibacterial agents in the core-shell micro/nanofibers. The antibacterial mechanism of this new kind of core-shell nanofibers may be different from the mechanism of Ag-doped antibacterial nanofibers [22,23]. One reason is that the PySMPU like PUPy53 and PUPyMDI35 contains large fraction of BINA unit which have an amido group in !…”

Abstract.A novel kind of shape memory polyurethane (SMPU) nanofibers with core-shell nanostructure is fabricated using coaxial electrospinning. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) results show that nanofibers with core-shell structure or bead-on-string structure can be electrospun successfully from the core solution of polycaprolactone based SMPU (CLSMPU) and shell solution of pyridine containing polyurethane (PySMPU). In addition to the excellent shape memory effect with good shape fixity, excellent antibacterial activity against both gramnegative bacteria and gram-positive bacteria are achieved in the CLSMPU-PySMPU core-shell nanofiber. Finally, it is proposed that the antibacterial mechanism should be resulted from the PySMPU shell materials containing amido group in ! position and the high surface area per unit mass of nanofibers. Thus, the CLSMPU-PySMPU core shell nanofibers can be used as both shape memory nanomaterials and antibacterial nanomaterials.

This article overviews the current research trends in the field of electroactive polymer poly(vinylidene fluoride) (PVDF) composites with various nanofillers, such as clay, carbon nanotube, graphene, and inorganic nanoparticles. Here we give a concise account on the preparation and properties of different nanocomposites, highlighting some of their applications. Important aspects such as PVDF nanocomposite properties, morphology, structure, thermal stability, mechanical properties, phase transitions, crystallinity, conductivity, dielectric permittivity, piezoelectric polymorph formation, electromagnetic induction shielding etc. are discussed. Particular emphasis is given on the piezoelectric β‐phase formation and the subsequent improvement of mechanical properties, conductivity, dielectric permittivity, and electromagnetic shielding, which are of interest in the application of PVDF nanocomposites in both commodity and technological fields. Apart from the binary nanocomposites, ternary nanocomposites containing two nanofillers and their synergistic effect on PVDF properties are also discussed.
