Description

technical field

[0001] The invention relates to a polyphosphazene-ether amide material and a preparation method thereof. Background technique

[0002] The special structure and superior performance of polyphosphazene (HCCP) determine its extensive research and application in many fields. At present, it mainly focuses on nonlinear optical materials, special rubber and elastic materials, separation membranes, flame retardant materials, solid electrolytes, and pharmaceutical and biomedical materials. Chemical Structure:

[0003]

[0004] Polyterephthalide-p-phenylenediamine (PPTA) fiber, known as aramid 1414 in our country, has heat resistance close to that of inorganic fiber, high dimensional stability at high temperature, and high flame retardancy. It will not shrink when in contact, and can retain the physical properties of the fiber for a long time, and its biggest feature is its low density, so the specific strength and specific modulus are several times higher than s...
