Manufacturing process of nanostructured deposition coatings

纳米多孔表面层和涂层在气体传感器、催化和光电子器件等领域有着非常广阔的应用前景。为了将纳米颗粒生产的基本技术带入成功的制造过程，需要制定受控和可重复的工艺条件的指导方针。尤其是多火焰喷雾原位气相混合的新进展，人们对其了解甚少。喷雾火焰混合相对于物种和温度的成功预测可以为定义的纳米界面创建一个有效的处理工具，例如针对许多类型的电子传输/存储问题(例如，水分解、太阳能电池)的异质结。该项目的主要目标是确定合适的工艺条件，通过使用火焰喷雾热解工艺和随后的纳米颗粒沉积来控制试件上纳米结构涂层和层的制造。为了开发和验证数值模型(Uni Blumenau)，采用实验数据采集(Uni Breme)来表示纳米粒子的生产和沉积过程，旨在进行工艺调整和放大研究。火焰和喷雾关键参数的现场实验过程监测将以激光诊断测量为基础。BRAGECRIM框架内的ManuNanoDep项目的主要目标可以概括为：-得出适合制造定制纳米结构涂层的工艺条件。-开发适用于过程监测的现场诊断技术(过程计量学)。-开发用于描述和衡量纳米结构沉积制造的综合综合工艺模型。

Nanostructured porous surface layers and coatings have very promising applications e.g. as gas sensor as well as in catalysis and optoelectronic devices. Guidelines for controlled and reproducible process conditions need to be derived for bringing the basic technology of nanoparticle production into successful manufacturing processes. Especially the very promising new development of in situ gas phase mixing of multiple flame sprays is only poorly understood. The successful prediction of spray flame mixing with respect to species and temperature can create an efficient processing tool for defined nano-interfaces such as heterojunctions for many types of electron transports / storage issues (e.g. water splitting, solar cells). The main aim of the project is the determination of the suitable process conditions for controlled manufacturing of nanostructured coatings and layers on specimen by employing the flame spray pyrolysis process with subsequent nanoparticle deposition. Experimental data acquisition (Uni Bremen) for the development and validation of numerical models (Uni Blumenau) is employed to represent the nanoparticle production and deposition processes aiming for process tailoring and scale-up studies. In situ experimental process monitoring of flame and spray key parameters will be based on laser diagnostic measurements.The main objectives of the project ManuNanoDep within the BRAGECRIM framework may be summarized as:- Derivation of suitable process conditions for manufacturing of tailored nanostructured coatings.- Development of suitable in situ diagnostic techniques for process monitoring (process metrology).- Development of combined integral process models for description and scaling of nanostructured deposition manufacturing.
