When, Where, and How was the Element Discovered Many chemists had speculated the presence of an unknown element having properties similar to chlorine in metal fluorides. In fact, Humphry Davy, a Cornish chemist, while trying to isolate it from hydrochloric acid, fell ill. ...
This article reviews the preparation, properties, and uses of poly(vinylidene fluoride) (PVDF or PVF 2 ), including preparation of 1,1-difluoroethene or vinylidene fluoride (VDF or ), and commercially important copolymers of VDF with other fluorinated comonomers. PVDF is commercially produced by...

Properties of FluorineFluorine shows different physical and chemical properties.Chemical Properties of FluorineFluorine is one of the most powerful oxidising agents since it is a strongly electronegative element. According to the Pauling scale, fluorine has an electronegativity of 3.98. The strong force ...
Fluorine's highest electronegativity and small atomic radius give unique properties to many of its compounds. For example, the enrichment of 235U, the principal nuclear fuel, relies on the volatility of UF6. Also, the carbon–fluorine bond is one of the strongest bonds in organic chemistry. This...
Physical and chemical properties. Fluorine gas has a density of 1.693 g/liter (0°C and a pressure of 0.1 meganewton/m2, or 1 kilogram-force/cm2), while liquid fluorine has a density of 1.5127 g/cm3 (at the boiling point). The melting point is – 219.61°C, and the boiling point,...
The structure of the sulfobetaines obtained was confirmed by 1 H--NMR spectra and IR spectra thereof. The table below shows the superior properties of aqueous solutions of sulfobetaines according to the invention in respect to their surface tension and their interfacial surface tension towards cycl...
