固体推进剂中的维生素:中性大分子键合剂的可控合成
Vitamins in Solid Propellants:Controlled Synthesis of Neutral Macromolecular Bonding Agents
摘要
Abstract
Composite solid propellant,serving as the propulsion source of various solid engines in missiles and space vehicles,consist of solid particles(oxidizer and metal fuel)embedded in polymer matrices(binders).This experimental teaching module addresses the challenge of"dewetting"under load in solid propellants,where adhesive and filler separation occurs,compromising interfacial interactions.Through controlled radical polymerization,a well-defined neutral macromolecular bonding agent with controlled molecular weight and composition was synthesized.Its molecular structure was characterized using hydrogen nuclear magnetic spectroscopy and gel permeation chromatography system.This comprehensive experimental teaching not only deepens students'understanding of solid propellant technology,but also enhances their awareness of fundamental principles and methodologies in the field of cutting-edge polymer chemistry.Furthermore,it cultivates students'experimental operation skills,proficiency with sophisticated instrumentation,and capability in result analysis,bridging cutting-edge scientific research with the national imperative for talent development in critical technological domains.关键词
