Initially, it was coated with a layer of polyvinylidene fluoride, a chemical chosen to enhance electrolyte affinity and thermal stability, while also introducing grafting reaction sites.

After health scares with polyvinylidene chloride, cling film is now often made with low-density polyethylene, though that's less, well, clingy.

But cellophane would soon fall out of fashion, overtaken by the likes of Dow Chemical's polyvinylidene chloride.

His work looked at the polyvinylidene fluoride detectors that make up the dust counter, which generate a charge when hit with a dust particle.

Because the nanofibers are made from organic polyvinylidene fluoride, or PVDF, they are flexible and relatively easy and cheap to manufacture.
