NOVELTY - The azide polyether thermoplastic elastomer based multi-phase composite micro/nano high-energy fiber membrane comprises fibers distributed in a staggered mode. On each fiber, 25-60 wt.% an azide polyether thermoplastic elastomer is used as a carrier to coat 35-70 wt.% nitramine explosive and 0.1-5 wt.% a nano combustion catalyst. The nano combustion catalyst is tightly attached to the surface interface of the nitramine explosive. USE - Azide polyether thermoplastic elastomer based multi-phase composite micro/nano high-energy fiber membrane. ADVANTAGE - The method has short preparation path, no need of post-treatment, and low product feeling, and can be molded at room temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the fiber membrane, which involves: adding the azide polyether thermoplastic elastomer and nitramine explosive into an organic solvent, and continuously stirring for 8-10 hours at room temperature until the materials are completely dissolved; slowly adding the nano combustion catalyst into the obtained solution, stirring for 1-3 hours, and then performing ultrasonic dispersion for 0.5-1 hour to obtain a spinning precursor solution; and preparing the multiphase composite micro/nano high-energy fiber membrane by using the spinning precursor solution and adopting an electrostatic spinning method.
