摘要
通过溶剂浇铸法制备了填充了两种粘土(无机结构的生高岭土(KAO)和有机结构的莱昂纳多石(LEO)以及 KAO/LEO 混合物)的聚乳酸(PLA)薄膜复合材料。本研究的主要目的是研究 LEO 和 KAO 共同加入聚乳酸基体后的单独效应和协同效应。通过 DSC、TGA、傅立叶变换红外光谱、扫描电镜、XRD、颜色、雾度和不透明度分析,研究了这些填料含量对复合材料形态和结构特征的影响。根据 TGA 分析,在聚乳酸中添加 LEO 后,Tmax2 明显降低。在含有 KAO/LEO 的薄膜中也可以看到这一结果。利用溶剂浇铸法,聚乳酸薄膜形成了两个熔点。P0 薄膜的 Tg、Tcc 和 Tm1 值低于其他薄膜。然而,所有薄膜的 Tg 值和 Tm2 值变化都很小。当 LEO 和 KAO 的用量达到 7.5% 时,薄膜的机械性能有所改善。3L 薄膜的机械性能最好。根据扫描电镜分析,所使用的填料大部分分布均匀,随着用量的增加,表面的填料出现了团聚现象。加入 LEO 和 KAO 后,表面颜色、视觉外观和不透明度都发生了显著变化。薄膜的雾度值接近 100。事实证明,这些薄膜复合材料改善了 P0 薄膜的许多性能。
Structure, performance, and crystallization behavior of Turkey leonardite and raw kaolin added polylactic acid composite films
Polylactic acid (PLA) film composites filled with two clays, Raw Kaolin (KAO), an inorganic structure, and Leonardite (LEO), an organic structure, as well as KAO/LEO mixtures, were prepared via solvent casting method. The main aim of this research was to investigate both the individual and the synergetic effects of LEO and KAO; they are incorporated together into a PLA matrix. The influence of these fillers content on the morphological and structural characteristics of the composites was investigated by the DSC, TGA, FT-IR, SEM, XRD, color, haze, and opacity analysis. According to the TGA analysis, significant decreases in Tmax2 were observed with the addition of LEO in PLA. It is also seen in films with KAO/LEO that support this result. Utilizing the solvent casting method, two melting points were formed in PLA films. The P0 film has lower Tg, Tcc, and Tm1 values than other films. However, there were small changes in Tg and Tm2 values in all films. Up to 7.5% amount of LEO and KAO, the mechanical properties of the films improved. The 3L film exhibited the best mechanical properties. The filler materials used were mostly homogeneously distributed, according to the SEM analysis, and as the amount increased, agglomerations were observed in the fillings on the surface. The addition of LEO and KAO changed the surface color, visual appearance, and opacity significantly. The haze values of films are near 100. These film composites have been shown to improve many properties of the P0 film.
