摘　　要：在实际工作中,亚光漆涂膜面上的手印难以清晰的显现,用水热法制备出磁性纳米四氧化三铁粒子(Fe3O4,40nm)可以改良现有方法。在亚光漆涂膜面上,与传统的磁性粉和银粉相比,磁性纳米四氧化三铁粒子显现的纹线更为流畅,细节特征清晰。这表明,磁性纳米四氧化三铁粒子可以有效显现亚光涂膜面客体上的手印,对于陈旧手印也有比较理想的显现效果,具有较好的应用前景。It was found difficult to show fingerprints on the matte coating materials in practical work.Toimprove the efficiency of the fingerprint development,we used Ferro ferric oxide nano particles(40nm)toshow the fingerprints.The fingerprint showed by Ferro ferric oxide nano powder is smoother and clearercomparing with traditional powder in matte coating.Research shows that the Ferro ferric oxide nano particlecan show matte coated surface object fingerprints effectively and is an effective reagent for the latentfingerprints.This paper verified it is feasibility,and laid the foundation for further research.
