Multiscale Modeling and Optimization of Nanoclearcoat Curing for Energy Efficient and Quality Assured Coating Manufacturing

Nanopaint is a new type of coating material that could offer significantly improved coating performance and/or a number of new functionalities, such as super scratch resistance, self-healing, surface texture alteration control, and toxic chemical/acid/corrosive agent repelling. However, how to ensure the achievement of the anticipated nanocoating performance and functionalities in coating manufacturing is a great challenge. In this paper, we introduce a multiscale modeling and analysis methodology for characterizing nanoclearcoat curing in a multi-stage manufacturing system. The methodology provides an opportunity to gain a deep understanding of the nanocoating formation process, which involves solvent evaporation, cross-linking reaction, and film thickness change at the presence of nanoparticles in the coating layer. The information provided by the integrated model facilitates the analysis of nanocoating quality the development of optimal operation strategies for energy efficient coating manufacturing. Methodological efficacy is demonstrated through a comprehensive case study. _____________________________________________________________________________ † For publication in Industrial and Engineering Chemistry Research (Special Issue on Sustainable Chemical Manufacturing). * All correspondence should be addressed to Prof. Yinlun Huang (Phone: 313-577-3771; FAX: 313-577-3810; E-mail: [email protected]).
