选择性热辐射聚酰亚胺复合织物的可控构筑及其红外隐身与电磁防护性能研究
Selective thermal radiation polyimide composite fabric for efficient infrared stealth and electromagnetic protection
摘要
Abstract
The low emissivity of traditional metal across the entire infrared spectrum causes excessive heat accumulation on the infrared stealth materials.It leads to an abnormally elevation in surface temperature,restricting the optimization of infrared stealth performance.In this paper,a robust selective thermal radiation polyimide composite fabric(PA66/Ni@PI)is prepared by integrating wet-chemical metallization with polyamide 66(PA66)coating on the surface of polyimide fabric(PI).A silver-activated electroless nickel plating effectively promotes the formation of conductive network with low infrared emissivity.Benefited from the existence of unique polyamide structure,the high transmittance of PA66 coating in 3-5 and 8-14 μm facilitates the expression of low-emissivity performance in Ni@PI,while the high absorptance of that in 5-8 μm endows PA66/Ni@PI with high emissivity for radiative cooling.As a result,an optimal infrared stealth performance can be successfully achieved under selective thermal radiation.Meanwhile,the formation of a continuous conductive nickel plating brings excellent electromagnetic interference shielding performance.Such outstanding comprehensive performance makes it possible for PA66/Ni@PI to become a potential candidate with competitive advantage in military camouflage.关键词
