Pyrolysis of fluorocarbon polymers
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961 The thermal decomposition of various fluorocarbon polymers were investigated; volatile products of the decomposition were determined along with the overall rates of volatilization, and from these rates the activation energies were calculated for the thermal degradation reactions.

Gamma irradiation of fluorocarbon polymers
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1961 Several fluorocarbon polymers were irradiated with Co60 gamma radiation at doses up to 1022 ev/g. The polymers studied included polytetrafluoroethylene, polytrifluoroethylene, polychlorotrifluoroethylene, a copolymer of tetrafluoroethylene with hexafluoropropylene, and several rubbery vinylidene fluoride copolymers.

Applications of fluorocarbon polymers in micromechanics and micromachining [PDF]
Sensors and Actuators A: Physical, 1994 Several thin-film deposition and etching techniques of the polymer fluorocarbon are investigated and the resulting thin-film properties will be compared with those of commercially available bulk polytetrafluoroethylene. The most promising deposition technique is performed in a conventional reactive ion etcher using a carbonhydrotrifluoride (CHF3 ...

Analogy of morphology in electrodeposited hydrocarbon and fluorocarbon polymers
RSC Adv., 2013 The control of the surface morphology is critical in the development of superhydrophobic surfaces. In this article, we report the synthesis of a novel 3,4-ethyleneoxythiathiophene (EOTT) platform and its fluorocarbon and hydrocarbon derivatives with various chain lengths (C8F17, C6F13, C4F9, C12H25, C10H21, C8H17).

Micellar polymers with hydrocarbon and fluorocarbon hydrophobic chains
, 2022 S.1091-1101Cationic ionenes bearing hydrophobic side chains were synthesized, which behave as micellar polymers of the polysoap type. The hydrophobic chains were either hydrocarbons or fluorocarbons, or a mixture of both, in the form of statistical as ...

Creation and recombination of free radicals in fluorocarbon plasma polymers
, 2022 S.33-43Generation and recombination processes of plasma-induced radicals in plasma polymers are investigated using ESR, which provides valuable information about radicals in thin polymer films. The polymer films are prepared by means of r.f.

Amyloid fibril formation of human recombinant insulin due to the interfacial hydrophobicity of fluorocarbon polymer membranes [PDF]
Exploration of BioMat-XAim: Although polytetrafluoroethylene (PTFE) is more hydrophobic than polyvinylidene fluoride (PVDF) in fluorocarbon polymer (FCP) membrane filters, it has been reported that the rate of amyloid fibril formation is faster on PVDF than on PTFE. To clarify
