Abstract:The present review briefly describes the development of the fluoropolymer industry in the past 70 years. Discussed are industrial fluoropolymers including polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinylidenefluoride, polyvinylfluoride, ETFE, ECTFE, FEP, PFA, THV, Teflon AF and Cytop. Nafion is included as a special functional fluoropolymer material. These industrial fluoropolymers are introduced in the order of their discovery or time of first production, included are their chemical structures, thermal properties, mechanical properties, electrical and electronic properties, optical properties, chemical resistance, oxidative stabilities, weather stabilities, processabilities and their general applications. The main manufacturing companies for the different types of fluoropolymer products are also mentioned.

“…[1,2] In this work, we used Teflon AF 1600, which contains 65% PDD, and is available from DuPont in powder form. While Teflon AF 1600 is, in the main, chemically inert, it is 12-15 wt% soluble in many perfluorinated solvents.…”

“…These properties include high temperature stability, unsurpassed chemical resistance, low water absorption, high optical clarity, and low dielectric constant. [1,2] One possible application would be its use as the insulator between conducting lines in computer packages, where the low dielectric constant (of about 1.9) would allow high signal speeds, [3,4] or perhaps as dielectric layers on integrated circuits. [5] Amorphous fluoropolymers have also been used as a combination anti-reflection and protection coating on optical crystals.…”

Amorphous fluoropolymer films have low dielectric constants and high chemical resistance and, so, have potential to be used as the insulator for high speed interconnects and as protection layers. Many applications would require high resolution patterning of the fluoropolymer film. We have found that these films are easily etched by reactive ion beam etching using an O 2 /Ar gas mixture. High etching rates of 600 nm/min with a 0.2 mA/cm −2 , 500 eV ion beam were obtained. This technique allows good selectivity with typical underlayers such as Si, Au, and photoresist. We have also found that a short Ar ion milling of the fluoropolymer surface allows good wettability of the film by photoresist.

“…Hence, light is scattered, and it has poor optical transparency. New classes of amorphous perfluorinated polymers with extraordinary properties were developed and commercialized by DuPont (as Teflon® AF), Asahi Glass (as Cytop®), and Solvay (as Hyflon® AD) . Teflon® AF and Hyflon® AD are a family of copolymers of 2,2‐bis(trifluoromethyl)‐4,5‐difluoro‐1,3‐dioxole and 2,2,4‐trifluoro‐5‐trifluoromethoxy‐1,3‐dioxole with TFE, respectively (Fig.…”

New amorphous perfluoro polymers: perfluorodioxolane polymers for use as plastic optical fibers and gas separation membranes

To address the need for perfluoro polymers with higher Tg, we have prepared and characterized various perfluorodioxolane monomers via direct fluorination of the hydrocarbon precursors. These monomers were readily polymerized in bulk or in solution initiated by perfluorodibenzoyl peroxide. The polymers obtained have relatively high Tg(~160°C) and exhibited low material dispersion. These polymers are completely amorphous and soluble in fluorinated solvents. The polymers are also chemically and thermally stable (Tg > 300°C). Thus, these perfluorodioxolane polymers may be used as plastic optical fiber material where high Tg is required, such as in automobile and aircraft application. These perfluorodioxolane polymers were also investigated for use as gas separation membrane. Among these polymers, the copolymer of perfluoro (2‐methylene‐1,3‐dioxolane) and perfluoro (2‐methylene‐4,5‐dimethyl dioxolane) showed superior gas separation performance compared with the commercial perfluoro polymers for a number of gas pair, including CO2/CH4, He/CH4, H2/CH4, and N2/CH4.
