本文研究了有机改性蒙脱土纳米粘土和相互作用增容剂对聚丙烯/聚对苯二甲酸丙二醇酯熔融共混物热性能的影响。动态力学分析表明，纳米粘土的加入使弹性模量提高，阻尼降低，α-弛豫峰上移，而β-弛豫峰不受影响。热重分析表明，共混物的热稳定性的协同效应伴随着分解速率的降低。在相容剂的存在下，这种效果更加明显。纳米粘土填料的加入通常导致耐热性的增强;然而，双重功能是明显的，即预防和催化，分别在降解开始之前和之后。
In this article, thermal properties of polypropylene/poly(trimethylene terephthalate) melt-mixed blends containing organically modified montmorillonite nanoclays and interacting compatibilizers are studied. Dynamic mechanical analysis showed an enhanced elastic modulus and reduced damping upon nanoclay fillers incorporation, also α-relaxation peak was shifted up while β-relaxation was not affected. Thermogravimetry exhibited a synergistic effect in thermal stability of the blend accompanied by a reduction in decomposition rate. This effect was more pronounced in presence of compatibilizers. The addition of nanoclay fillers generally led to an enhancement of thermal resistance; however, a dual function was evident, namely preventive and catalytic, respectively prior to and after onset of degradation.
