采用溶液共混和熔融混合两种方法制备了聚丁二酸丁二醇酯（PBS）/有机粘土纳米复合材料。此外，还通过两步法制备了 PBS/有机粘土纳米复合材料，其中溶液共混混合物随后使用扭矩流变仪在熔融状态下复合（SOAM 方法）。然后，我们首先研究了 PBS/有机粘土纳米复合材料的热性能和机械性能，并确定了制备纳米复合材料泡沫的最佳有机粘土含量。当通过光学显微镜检查时，发现所有 PBS/有机粘土纳米复合泡沫都具有闭合的球形泡孔，没有任何破裂。吹塑比也随着吹塑温度和时间的增加而增加，最大吹塑比为19。此外，发现添加少量有机粘土可以使泡孔尺寸遵循高斯分布。聚合物。 ENG。 SCI., 51:1316–1324, 2011。2011 年塑料工程师学会
Poly(butylene succinate) (PBS)/organoclay nanocomposites were prepared by both solution blending and melt mixing methods. In addition, nanocomposites of PBS/organoclay were also prepared by a two-step process where the solution blended mixture is subsequently compounded in the melt state using a torque rheometer (SOAM method). We then investigated thermal and mechanical properties of the PBS/organoclay nanocomposite at first and determined an optimum organoclay content for the preparation of nanocomposite foams. All PBS/organoclay nanocomposite foams are found to possess closed sphericalshaped cells without any rupture when examined by an optical microscopy. The blowing ratio also increased with the increase in the blowing temperature and time, with the maximum blowing ratio of 19. Furthermore, the addition of a small amount of organoclay is found to allow the cell size to follow Gaussian distribution. POLYM. ENG. SCI., 51:1316–1324, 2011. a 2011 Society of Plastics Engineers
