PVDF

PVDF polyvinylidene fluoride is translucent or white powder or particle in appearance, closely arranged between molecular chains, and has strong hydrogen bond. The oxygen index is 46%, nonflammable, the crystallinity is 65%~78%, the density is 1.17~1.79g/cm3, the melting point is 172 ℃, the thermal deformation temperature is 112~145 ℃, and the long-term use temperature is - 40~150 ℃.

2. Common applications of PVDF

However, the stability to light and heat is poor. When it is above 100 ℃ or exposed to the sun for a long time, it will decompose to produce hydrogen chloride, and further autocatalytic decomposition will cause discoloration, and the physical and mechanical properties will also decline rapidly. In practical applications, stabilizers must be added to improve the stability to heat and light.

3. Development history of PVDF

PVDF is a kind of high-strength and corrosion resistant material, which is usually used to make water pipes. PVDF membrane can bind proteins, and can separate small segments of proteins. It was originally used for protein sequencing. Because the nitrocellulose membrane can be degraded in Edman reagent, PVDF was found as a substitute. Although PVDF membrane binding protein is not as efficient as nitrocellulose membrane, it is stable Corrosion resistance makes it an ideal product for protein sequencing, which has been used until now. PVDF membrane, like nitrocellulose membrane, can be used for various dyeing and chemiluminescence detection, and has a wide range of applications. The sensitivity, resolution and protein affinity of this PVDF membrane are higher than those of conventional membranes under fine process, which is very suitable for the detection of low molecular weight proteins.
