| 英文摘要 | Effects of an ionic liquid, 1-n-tetradecyl-3-methylimidazolium bromide ([C14MIM] Br), as a foaming additive on the foaming behavior of polypropylene(PP) by supercritical CO2 technique was reported. Mass ratio of PP/[C14MIM] Br up to 100: 10 was incorporated via melt blending. The melting behavior and fractured morphology of PP/[C14MIM] Br samples were investigated by differential scanning calorimetry(DSC) and scanning electron microscopy(SEM), respectively. The CO2 sorption was measured by commonly accepted gravimetric method. The results of DSC and CO2 sorption experiments show that [C14MIM] Br has little effect on the crystallinity, melting point and the mass uptake of CO2 of PP. SEM images reveal that [C14MIM] Br forms a well-dispersed phase, whose size increases with [C14MIM] Br content, in the PP matrix. The foamed PP/[C14MIM] Br samples exhibit close cell structure, increased cell size and decreased unfoamed region and bulk density, compared with pure PP foamed under the same saturation conditions of 155 degrees C/10 MPa, indicating ionic liquid [C14MIM] Br has significant effect on the foaming behavior of PP. |
