Research Applications

  • PTFE tube can be used to prepare PTFE membrane flow reactor for aerobic oxidation reaction. Because PTFE tube is impermeable and non-reactive, harmful interaction between Cu catalyst system and steel tube can be avoided, it is an alternative traditional stainless steel reactor. Studies have shown that PTFE tubes have sufficient oxygen permeability and can be used as membranes in tube-in-shell reactors. The prepared reactor exhibits excellent performance, which can be used for continuous flow reactions using gaseous reagents.

  • PTFE rods can be used for some theoretical studies on interfaces, such as corona propagation and charge deposition on the surface of PTFE [2], or some solid-liquid interface scientific issues, such as the critical meniscus height of liquid with round edges. Studies have shown that for two liquids, water and glycol, the more lyophobic PTFE rod shows a higher meniscus than the polycarbonate rod. [3]
