Research Topic

A systematic approach to investigate Materials-Processing-Property-Structure (MaP2S) relationship in selected classes of chemical products

Abstract

The aim of chemical product design is to come up with a product with a desired set of target properties. Ingredients and product structure are two key drivers of product quality having direct effect on the physical, mechanical, electrical, and thermal properties of chemical products. Whereas the choice of a pure ingredient with given material properties can be conveniently made based on available information in the literature and predictive methods, the prediction of the properties of a mixture is still a challenging task. At present, there is a keen interest in finding a relationship of product properties with materials involved, structure and processing in product manufacturing that has broad and direct implications on chemical product design. This study extends prior work on Grand Product Design Model covering product conceptualization, ingredients selection and properties, product structure, and processing conditions and techniques. The main purpose of this research is to develop a well-organized design framework on Material-Property-Processing-Structure (MaP2S) relationship for selected classes of chemical products that effectually provide the guidelines for design and development with special emphasis on examining the relationship between product structure and property. The preliminary MaP2S framework is developed at first in section 2, and applied to heat conductive polymer composite by using a case study on die attach adhesive (DAA) in section 3. Mostly heuristics are used for ingredients selection, while topology optimization is adopted to generate optimized microstructure with respect to target property by employing spatial branch and bound method of mixed integer nonlinear programming. The initial results show good agreement when tested on a commercial simulation platform that provide confidence to go for more complex problems in future. After having conclusive evidence from section 3, the same MaP2S design framework will be used for certain types of food and personal care emulsions in section 4 and 5 respectively.
