摘要

复合材料是一种具有多相的材料,因其能够改善孤立材料的物理和化学特性而备受关注。从这个意义上说,这些复合材料通常被用作两种用途的关键成分:着色和改善操作性能;此外,它们还有符合绿色化学原则的替代合成路线。因此,本报告利用天然产品靛蓝和高岭石开发了一种新的复合材料,作为一种新的无毒指痕显影剂应用于乳突镜检查。该复合材料通过绿色程序获得,并通过光谱和色谱技术进行了表征。因此,为了研究这种材料作为指痕显影剂的潜力,我们采用了不同的技术,如损耗、老化、与商用粉末比较以及在不同表面显现潜伏指痕。测试表明,即使经过 15 天的沉积,复合材料与潜伏指痕的对比度和附着力都很好。本研究介绍了一种天然靛蓝/高岭石复合粉末,与商用指纹粉末相比,这种粉末显示出相似或更高的效率,并能形成可识别的天然和皮脂腺指印。- 复合材料由环保材料制成。- 复合材料的形成遵循了绿色化学和低成本的理念。-该复合材料可用作潜伏指印显影剂。

The effectiveness of natural indigo/kaolinite composite powder in the development of latent fingermarks
Composites are materials that have multiple phases and have attracted much attention as they are able to improve physical and chemical properties of an isolated material. In this sense, these composites are commonly used as key components for two purposes: coloring and improving the operational properties; besides that, they have alternative synthesis routes that respect the principles of green chemistry. Thus, this reports the development of a new composite using natural products, indigo and kaolinite, for application in papilloscopy as a new nontoxic fingermark developer. The composite was obtained via green procedures and was characterized by spectroscopic and chromatographic techniques. Thus, to investigate the potential of the material as a fingermark developer, different techniques were applied such as depletion, aging, comparison with commercial powder, and development of latent fingermarks on different surfaces. Tests revealed that the composite presented good contrast and adhesion with the latent fingermarks, even after 15 days of deposition. This study presents a natural indigo/kaolinite composite powder that showed similar or higher efficiency when compared to the commercial fingerprint powder and was able to develop identifiable natural and sebaceous fingermarks. • A composite was formed from eco-friendly materials. • The composite formation follows the concepts of green chemistry and low cost. •The composite was applied as a latent fingermark developer.
