Abstract Polytetrafluoroethylene (PTFE) is one of the most significant fluoropolymers, and one of the most recent initiatives is to increase its performance by using metal oxides (MOs). Consequently, the surface modifications of PTFE with two metal o

On the Spectroscopic Analyses of Polytetrafluoroethylene Coated with Nano ZnO and SiO2

Autor: Maroof A. Hegazy, Rasha Ghoneim, Hend A. Ezzat, Heba Y. Zahran, Ibrahim S. Yahia, Hanan Elhaes, Medhat Ibrahim

On polytetrafluoroethylene (PTFE) polymer nanocomposites coated with basically two metal oxides (MOs), SiO2 and ZnO, as well as a mixture of the two MOs, density functional theory (DFT) computations were performed. The B3LYPL/LAN2DZ model was used to
