纳米颗粒沉积技术有望简化薄膜沉积，同时通过控制薄膜密度、孔隙率和组成来增强性能。在本文中，二氧化铈纳米颗粒沉积从溶液到薄膜通过旋涂。的纳米粒子的形状和薄膜形态之间的比较，从不同的混合方法沉积。本文分别采用传统的间歇沉淀反应器和连续微通道反应器（T型混合器）进行了不同混合方式的研究。初步结果表明，不同的颗粒形状和膜形态作为前体浓度的函数。微通道方法的优点包括更好地控制纳米颗粒的形状和更均匀的膜，更少的团聚。Copyright © 2007 by ASME
Nanoparticle deposition techniques hold the promise of simplifying thin film deposition while enabling enhanced performance through the control of film density, porosity and composition. In this paper, ceria nanoparticles are deposited from solution to a film via spin coating. A comparison is made between the nanoparticle shape and film morphology produced by depositing from different mixing approaches. In this paper, different mixing approaches were carried out by using traditional batch precipitation reactor and continuous microchannel reactor (T-mixer). Preliminary results show different particle shape and film morphology as a function of precursor concentration. Advantages of the microchannel approach include better control of nanoparticle shape and more uniform film with less agglomeration.Copyright © 2007 by ASME
