| 英文摘要 | The objective of the present work was to report the unprecedented cell structure variation in multilayered alternating polystyrene (PS)/PS-SiO2 foams. The multilayered alternating PS/PS-SiO2 foams were prepared via a coextrusion technique and a subsequent batch foaming process with high-pressure carbon dioxide (CO2). The multilayered PS/PS-SiO2 stacks were controlled of different layers (2, 4, 8, 16, 32, 64, and 128) using the layer-multiplying elements (LMEs). The PS-SiO2 nanocomposite was prepared using a twin-screw extruder with 99 wt % PS resins and 1 wt % SiO2 nanoparticles. With the increase of the layer number, three types of cell structures were observed: alternating big-cell/small-cell layers, a single big-cell layer in small-cell layers, and alternating film/small-cell layers. The original big cells were formed in the pure PS layer, and the small ones in the PS-SiO2 layers. It was considered that the decrease in the thickness of the pure PS layer and the increase in the thickness of the PS-SiO2 layer due to the interfacial mixing between the adjacent layers is the reason for the unprecedented cell structure variation. A possible mechanism was proposed for interpreting the cell structure variation in the preparation of multilayered PS/PS-SiO2 foams. The interfacial mixing can be taken as the strategy to tune the cell structures for the purpose of end-use demands in preparing multilayered foams using the same polymer in adjacent layers. |
