Facile Preparation and Properties of Crosslinked Copolyether Elastomers with 1,2,3‐Triazole and Urethane Subunit via Click Polymerization

ChemistryOpen, Volume 8, Issue 5, Page 571-579, May 2019., 2019
Click and cross: A novel azide terminated ethylene oxide‐tetrahydrofuran copolymer with urethane segments (ATUPET) has been prepared through a facile method. The elastomers based on ATUPET exhibited improved mechanical properties and satisfactory thermal stability, which indicated that this might be a promising polymeric binder for future propellant ...

Research Progresses of Flash Evaporation in Aerospace Applications

International Journal of Aerospace Engineering, Volume 2018, Issue 1, 2018., 2018
Liquid is overheated and evaporated quickly when it enters into the environment with lower saturation pressure than that corresponding to its initial temperature. This phenomenon is known as the flash evaporation. A natural low‐pressure environment and flash evaporation have unique characteristics and superiority in high altitude and outer space ...
