PVDF is one of the few plastics that meets these high purity requirements, which is why manufacturers use it not only for pipes and hoses but also for other components such as acid baths, complete piping systems, and transport and storage vessels.

The Japanese physicist H. Kawai discovered its piezoelectric properties more than forty years ago. A few years later, two further Japanese physicists, K. Nakamura and Y. Wada, demonstrated the material\u2019s ferroelectric properties. The piezoelectric effect describes the generation of a voltage through directed external pressure on a material, and engineers use it to measure vibration or rotation, for example in buildings, vehicles or machinery. These sensors contain a thin PVDF film that converts even the smallest movements into an electrical signal.<\/p>\n<figure id=\"attachment_2003\" aria-describedby=\"caption-attachment-2003\" style=\"width: 600px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2003 size-full\" title=\"Hearing aid\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/Hoergeraet.jpg\" alt=\"hearing-aid\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/Hoergeraet.jpg 600w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/Hoergeraet-300x200.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><figcaption id=\"caption-attachment-2003\" class=\"wp-caption-text\">\u00a9 aigarsr \/ Fotolia.com<\/figcaption><\/figure>\n<p style=\"text-align: justify;\">Engineers also exploit the opposite effect, the build-up of pressure when an external voltage is applied. As so-called actuators, films are used in components such as transistors or diodes, where they act as control elements. In medical technology, manufacturers build PVDF membranes into cochlear implants for people with hearing impairments. External sound waves set a membrane implanted in the cochlea vibrating, which induces electrical voltages of differing strength depending on the frequency. This imitates the basilar membrane of the inner ear: the auditory nerve \u201cmeasures\u201d the resulting voltages and passes them on to the brain. Cochlear implants are commercially available and allow people with hearing impairments to regain their hearing.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Plastics_as_Storage_Media_and_Motion_Detectors\"><\/span>Plastics as Storage Media and Motion Detectors<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: justify;\">A sudden change in external temperature can likewise generate a measurable electrical voltage in films made of polyvinylidene fluoride. Motion and flame detectors make use of this pyroelectric effect. The ferroelectric effect occurs when the dipole moments present in a material align with an external electric field. Researchers are working on how materials with this property can serve as storage media for electronic data.<\/p>\n<blockquote>\n<p style=\"text-align: justify;\">Plastic transistors and diodes made from PVDF film already exist; a storage medium made from this material is still the subject of research.<\/p>\n<\/blockquote>\n<h2><span class=\"ez-toc-section\" id=\"PVDF_Membranes_in_Biochemical_Analysis\"><\/span>PVDF Membranes in Biochemical Analysis<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Biochemists use PVDF membranes to immobilise proteins. In western blotting, or immunoblotting, proteins separated on an SDS gel are transferred to a membrane, immobilised there and then identified using antibodies. Either nylon or PVDF membranes are used &#8211; proteins bind to both materials. Compared with nylon membranes, polyvinylidene fluoride offers the advantage of a greater protein-binding capacity as well as higher stability and robustness. This also allows the membranes to be reused once a washing procedure has removed the bound proteins. Alternatively, the PVDF membrane can be modified so that it has a very low protein-binding capacity. Such a membrane is used in the sterile filtration of solutions to reliably remove bacteria, unwanted proteins and other accompanying substances.<\/p>\n<p><center><a href=\"https:\/\/www.rct-online.de\/en\/fasteners\/washers-and-rings\/30443\/washer-din-125-made-of-pvdf\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2030 size-full\" title=\"Washer (DIN 125) made of PVDF (polyvinylidene fluoride) | colour: natural, slightly translucent\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/unterlegscheibe-din-125-pvdf.jpg\" alt=\"washer-din-125-pvdf\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/unterlegscheibe-din-125-pvdf.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/unterlegscheibe-din-125-pvdf-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a> <a href=\"https:\/\/www.rct-online.de\/en\/fasteners\/screws\/slotted-cheese-head-screw\/30477\/slotted-cheese-head-screw-din-84-made-of-pvdf\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-2031 size-full\" title=\"Slotted cheese head screw (DIN 84) made of PVDF (polyvinylidene fluoride) | colour: natural, slightly translucent\" src=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/zylinderschraube-din-84-pvdf-schlitz.jpg\" alt=\"slotted-cheese-head-screw-din-84-pvdf\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/zylinderschraube-din-84-pvdf-schlitz.jpg 300w, https:\/\/www.rct-online.de\/magazin\/wp-content\/uploads\/2018\/07\/zylinderschraube-din-84-pvdf-schlitz-150x150.jpg 150w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/a><\/center><\/p>\n<h2><span class=\"ez-toc-section\" id=\"PVDF_%E2%80%93_A_Material_with_a_Future\"><\/span>PVDF \u2013 A Material with a Future<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: justify;\">Polyvinylidene fluoride, a plastic first synthesised more than fifty years ago, has found its way into many areas of everyday life.
