A polyvinylidene fluoride (PVDF) film-based capacitive biosensor was developed for glucose sensing. This device consists of a PVDF film sandwiched between two electrodes. A capacitive biosensor measures the dielectric properties of the dielectric layers at the interface between the electrolyte and the electrode. A glucose oxidase (GOx) enzyme was immobilized onto the electrode to oxidize glucos...

Although polyvinylidene fluoride (PVDF) is non-toxic and stable in vivo, its hydrophobic surface has limited its bio-applications due to poor cell-material interaction and thrombus formation when used in blood contacting devices. In this study, surface modification of PVDF using naturally derived non-mammalian collagen was accomplished via direct surface-initiated atom transfer radical polymeri...

An improved high throughput assay for measuring murine antibodies to squalene (SQE) is described. The assay is highly reproducible and sensitive and can detect 80 ng/ml of antibody to SQE. The assay, an ELISA, is similar to our previously described assay in which plates containing PVDF membranes were used [J. Immunol. Methods 245 (2000) 1]. The PVDF plates worked well for detection of murine mo...

Polymer solid electrolytes (SEs) with high safety and flexibility are ideal for advanced lithium-metal solid-state batteries (SSBs). Among various polymer SEs, polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) SEs have gained increased attention their dielectric constants, ionic conductivity, excellent flexibility. However, severe side reactions at the interface caused by decomposition ...

Polyvinylidene difluoride (PVDF) is a ferroelectric polymer characterized by negative strain along the direction of applied electric field. However, electromechanical response mechanism PVDF remains unclear due to complexity hierarchical structure across length scales. As described in this letter, we employ Finsler geometry model as new solution aforementioned problem and demonstrate that defor...

Most polymer materials are thermal and electrical insulators, which have wide potential in advanced energy-power applications including energy conversion. However, polymers get softened when contact with heat, causes their molecular chains to flow as the temperature increases. Although dielectrics exhibit high power density, they face challenges of low density is due dielectric permittivity ass...
