英文摘要： The cell morphology controllability of microporous foamed polymer is the bottleneck and major problem to achieve its industrial production and expand the application areas. This project proposes a theoretical method that adding nanoparticles to the microcellular foamed polymer molding process to control the cell morphology of microcellular foamed polymer. Firstly, the nanoparticles quantitative processing method is used to study the mechanism of action between the nanoparticles and the microcellular foaming process, and it provides theoretical support for the realization of the cell morphology controllability. Secondly, the regulative mechanism of the nanoparticles on the microporous structure morphology of the polymer is studied to establish the quantitative relationship between them, and the mechanism of action of the cell morphology is covered under the matix and process parameter coupling condition. Finally, the precise control of the microcellular foamed polymer molding process is surveyed under the action of nanoparticles to predict the material performance. This project is expected to realize the quantitative control of cell morphology of microcellular foamed polymer and provide the basic theoretical methods for the industrialization of microcellular foamed polymer.
