    Chemical Structure DescriptionAn Interactive 3-Dimensional (3D) Visualization of Carbon TetrafluorideAdditional Information For Identifying Carbon Tetrafluoride MoleculeAdditional Outstanding ProductsCarbon Tetrafluoride Identification Summary Frequently Asked QuestionsA chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. The CARBON TETRAFLUORIDE molecule contains a total of 4 bond(s) There are 4 non-H bond(s). Images of the chemical structure of CARBON TETRAFLUORIDE are given below: The 2D chemical structure image of CARBON TETRAFLUORIDE is also called skeletal formula, which is the standard notation for organic molecules. The carbon atoms in the chemical structure of CARBON TETRAFLUORIDE are implied to be located at the corner(s) and hydrogen atoms attached to carbon atoms are not indicated – each carbon atom is considered to be associated with enough hydrogen atoms to provide the carbon atom with four bonds. The 3D chemical structure image of CARBON TETRAFLUORIDE is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. The radius of the spheres is therefore smaller than the rod lengths in order to provide a...

  • Selective Etching of Semicrystalline Polymers: CF4 Gas Plasma

    Abstract. A series of poly (ethylene) (PE) films with different degrees of crystallinity was treated with a radio-frequency tetrafluoromethane (CF 4) gas plasma (48−49 W, 0.06−0.07 mbar, and continuous vs pulsed treatment). The etching behavior and surface chemical and structural changes of the PE films were studied by weight measurements, X-ray photoelectron spectroscopy (XPS), static and dynamic water contact angle measurements, scanning electron microscopy (SEM), and atomic force
