摘要

为了获得具有良好红外吸收特性及低发射率复合颜料，通过将纳米NiO复合于片状金属铝粉表面的方法，获得了复合效果好的纳米NiO/Al复合粒子.为了保证复合物的红外伪装性能，通过对复合前驱体Ni2CO3(OH)2/Al的热分析，确定了对复合物的热处理温度.通过对复合物热处理前后的电镜照片分析，发现热处理前复合物表面是由线状的Ni2CO3(OH)2交织而成的，而热处理后则变成了由纳米球状NiO粒子连接而成的球链.这种现象在同类研究中尚未见报道.对比所制备的纳米NiO/Al和NiO的XRD图谱，发现纳米NiO/Al中的NiO衍射峰宽化，表现出纳米粒子的特征，由半高宽计算出其晶粒粒径为12 nm.

Abstract

To obtain composite paint with good infrared absorption and low emissivity

nanometer NiO/Al composite particle was prepared with nanometer compounding technique. To ensure the IR camouflage performance of the composite

heat treatment temperature was fixed by heat analysis on composite intermediate of Ni2CO3(OH)2/Al.The results of SEM on composite fore-and-after heat treatment indicated that NiO on the composite surface became nanometer sphere after heat treatment from wire-like Ni2CO3(OH)2.This phenomenon has not been reported in similar fields up to now. Compared with the XRD charts of NiO/Al and NiO prepared in experiment

it was found that the diffraction peaks of NiO of NiO/Al were broadened

and the characteristics of nanometer particles were shown evidently.The crystal diameter of NiO in composite particles was 12 nm

calculated by the width of the curve peak at half height.
