以过氧化二异丙苯为引发剂,在不同配比下对腰果酚与聚乳酸(PLA)进行接枝反应,并对其力学性能、热性能进行了表征。在不存在过氧化二异丙苯(DCP)的情况下,随着腰果酚含量的增加,PLA/腰果酚共混物表现出典型的塑性行为,即拉伸强度降低,断裂伸长率增加,而缺口冲击强度保持较低水平,直到腰果酚含量达到20 wt.%。当DCP引入共混物中时,仅15 wt. %腰果酚含量以显著改善缺口悬臂梁冲击强度。热性能测试结果表明,在低腰果酚含量下,接枝腰果酚后的聚乳酸冲击强度进一步提高。
Grafting reaction between poly (lactic acid) (PLA) and cardanol was initiated by dicumyl peroxide at different compositions, and the mechanical, thermal properties were characterized. In absence of dicumyl peroxide (DCP), the PLA/cardanol blends showed a typical plastic behavior with increasing cardanol content, i.e. decrement of tensile strength, accompanied by increment of elongation at break, while the notched Izod impact strength kept low level until the cardanol content reached 20 wt.%. When DCP was introduced into the blends, only 15 wt. % cardanol content was needed to improve the notched Izod impact strength significantly. According to the thermal behavior testing results, the grafting of cardanol onto PLA chains might take responsibility for the further improvement of impact strength with less cardanol content.
