介绍了聚合物对微/纳米铝粉表面改性的四种包覆机理,分析认为化学键作用机理、吸附层媒介作用机理相对于库仑静电引力作用机理、过饱和度机理具有作用力强、包覆性好的优点。分析并比较了聚合物包覆微/纳米铝粉常用的几种聚合方法的优缺点及适应性,为后续开展研究工作提供了有益的选择依据。综述了几种常用聚合物包覆微/纳米铝粉的研究进展,指出含能聚合物包覆微/纳米铝粉在固体推进剂中的应用具有广阔的前景。

Four kinds of coating mechanisms of the surface modification for micro/nano aluminum powders with polymer were introduced, and it is found that the chemical bonding mechanism and the adsorption layer medium mechanism relative to the coulomb electrostatic attraction mechanism and the mechanism of over - sat- uration had good advantages such as intense action and fine covering properties. Then the advantages, disad- vantages and adaptability of several polymerization methods of polymer coated micro/nano aluminum powders were analyzed and compared, providing a useful selection basis for subsequent research work. Finally, the re- search progress of several polymer coated micro/nano aluminum powders were reviewed in details, and it is pointed out that the energy-containing polymer coated rnicro/nano aluminum powders had a good prospect of application for the solid rocket propellant.
