摘要

为了研究增塑剂官能团对淀粉增塑的影响,本研究选择了三种不同的增塑剂:乙二醇(EG)、乙二胺(EDA)和乙烯双甲酰胺(EBF)。利用分子动力学(MD)模拟构建了增塑剂/淀粉体系的三个模型,分析包括计算每个体系的均方位移(MSD)、径向分布函数(RDF)和氢键能。此外,还利用模拟比例制备了热塑性淀粉薄膜,随后对薄膜进行了 DSC、XRD、傅立叶变换红外光谱、扫描电镜和机械性能测试。通过对三种体系的模拟数据和制备的热塑性淀粉(TPS)性能进行比较分析,发现增塑剂的不同官能团对淀粉塑化有显著影响。在不同的增塑剂官能团类型中,可以观察到 EG 中的羟基和 EDA 中的氨基主要与淀粉分子链中的羟基形成氢键。相比之下,EBF 中的酰胺基不仅能与淀粉的羟基形成氢键,还能与淀粉主链上的醚键形成氢键,从而使淀粉塑化更有效。

Effect of functional groups of plasticizers on starch plasticization

To investigate the impact of plasticizer functional groups on starch plasticization, three distinct plasticizers were selected in this study: ethylene glycol (EG), ethylenediamine (EDA), and ethylenebisformamide (EBF). Three models of the plasticizer/starch system were constructed using molecular dynamics (MD) simulations, and the analysis encompassed the computation of mean square displacement (MSD), radial distribution function (RDF), and hydrogen bonding energy for each system. Additionally, the proportions of simulation were used to prepare thermoplastic starch films, which were subsequently subjected to examinations such as DSC, XRD, FT-IR, SEM, and mechanical property testing. Comparative analysis of the simulation data from the three systems and the properties of the manufactured thermoplastic starch (TPS) established that the diverse functional groups of plasticizers significantly influenced starch plasticization. In different plasticizer functional group types, it was observed that hydroxyl groups in EG and amino groups in EDA predominantly form hydrogen bonds with hydroxyl groups in starch molecular chain. In contrast, amide groups in EBF can establish hydrogen bonds not only with hydroxyl groups of starch but also with ether bonds on the starch main chain, thereby resulting in more effective starch plasticization.
