STUDY ON PREPARATION OF NANO LATENT MATERIALS WITH HALLOW CENOSPHERE AS NUCLEAR

叙述了纳米金属微粒及金属氧化物微粒的吸波隐形原理和空心微珠为基核载体 ,表面镀覆纳米金属微粒Cu、Ni及金属氧化物微粒TiO2 ,制备隐形材料的工艺过程。作为吸波材料的基体 ,空心微珠的粒度 0～ 10 μm较好 ,控制一定的金属置换与沉降速度 ,可获得在 470～ 35 0 0nm、389～ 415nm波长内具有较高吸收率 (>85 % )的空心微珠镀Cu、Ni、TiO2

The technology of plating nano tiny particles of metals such as Cu,Ni and metal oxides such as TiO 2 on the cenosphere surface and the relative principle of absorbing light wave was introduced *'This technology has been used for preparation of latent materials The granular size of cenospheres as the matrix of light absorbing materials is better between 0μm and 10μm By controlling the sedimentation and exchange rates of metals and metal oxides,the light absorbing materials having cenospheres plated with Cu,Ni or TiO 2 and a high absorption rate in wavelength ranges of 470～3500nm and 389～415nm were obtained
