Abstract

The fractionation of diatomaceous earth (DE) using sedimentation made it possible to obtain separate unbroken diatom fractions from broken or agglomerated bodies with a range of particle sizes. The produced filler was used to prepare polylactide (PLA)/diatomaceous earth biocomposite samples containing different particle sizes, which were subjected to mechanical testing (tensile strength, flexural strength, impact strength), colloidal testing (contact angle, color change test, SEM/EDS), and thermal testing (TGA, DSC, DMA). Modification of the PLA containing the smallest particle size with diatomaceous earth (Fraction 5) resulted in a higher impact strength compared to both the pure PLA and the PLA/DE composite that contained base diatomaceous earth. Furthermore, the melt flow rate was improved by more than 80 and 60% for the composite modified with fractionated diatomaceous earth (Fraction 4) compared to pure PLA and base diatomaceous earth, respectively. The elasticity of the composite was also improved from 3.3 GPa for pure polylactide to 4.4 GPa for the system containing the smallest diatomaceous earth particles (Fraction 5).

摘要

采用沉降法对硅藻土（DE）进行分级分离，从而能够从破碎或团聚的硅藻土中获得一系列不同粒径的完整硅藻组分。所制备的填料用于制备含有不同粒径的聚乳酸（PLA）/硅藻土生物复合材料样品，并对其进行力学性能测试（拉伸强度、弯曲强度、冲击强度）、胶体性能测试（接触角、颜色变化测试、扫描电子显微镜/能谱分析）以及热性能测试（热重分析、差示扫描量热法、动态热机械分析）。与纯PLA和含有未分级硅藻土的PLA/DE复合材料相比，用硅藻土（组分5）对粒径最小的PLA进行改性后，其冲击强度更高。此外，与纯PLA和未分级硅藻土相比，用分级硅藻土（组分4）改性的复合材料的熔体流动速率分别提高了80%以上和60%以上。复合材料的弹性也从纯聚乳酸的3.3 GPa提高到含有最小粒径硅藻土颗粒（组分5）体系的4.4 GPa。
