Structural Analysis of VDF-TFE Copolymer

The vinylidene fluoride copolymer with tetrafluoroethylene P (VDF-TFE) was investigated. The microstructure of its chains was studied with the ¹⁹F NMR method, employing the ¹⁹F type of fluorine isotope with a number of protons equal to 19. The spectra of solutions in acetone-d₆ were recorded with H-decoupling at 303 K using the Bruker Avance II spectrometer (Bruker Corporation, Karlsruhe, Germany) operating at the fluorine frequency of 282.48 MHz. The ¹⁹F NMR chemical shifts were referenced externally to CFCl₃ (0 ppm).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
