摘要: 以聚丁二酸丁二醇酯(PBS)为基体,ST-CE37B为扩链剂,通过熔融共混法制备扩链PBS,然后以超临界CO2为发泡剂,通过快速卸压制备PBS开孔泡沫。结果表明,扩链剂的加入使PBS的储能模量提高1个数量级,结晶温度上升7.69 ℃。当发泡温度为100 ℃,发泡压力为20 MPa时,制得的PBS泡沫开孔率可达96.58 %,CCl4吸附量为31.76 g/g,可快速从水中去除CCl4和环己烷。

Abstract: In this study, poly(butylene succinate) (PBS) and ST-CE37B were used as a matrix and an chain extender, respectively, to prepare chain extended PBS samples through melt blending. Furthermore, the open-cell PBS foams were prepared by using a supercritical CO2 foaming method. The results indicated that the addition of chain extender increased the storage modulus of PBS by one order of magnitude and resulted in an increase in its crystallization temperature by 7.69 ℃. When the foaming temperature was 100 ℃ and the foaming pressure was 20 MPa, the open cell content and adsorption capacity for CCl4 of the CPBS foam reached 96.58 % and 31.76 g/g, respectively. Moreover, CCl4 and cyclohexane in water were both removed quickly by the CPBS foam.
