Abstract

Interesting alternatives to expensive biodegradable polymers are their composites with natural fillers. The addition of biochar to a blend of poly(lactic acid) (PLA) and poly(3-hydroxybutyrate--4-hydroxybutyrate) was studied, and the resulting materials were evaluated for their properties and changes during degradation. Introducing biochar as a filler brought a noticeable improvement in electrostatic properties. Surface resistivity decreased from 3.80 × 10 for the sample without biochar to 1.32 × 10 for the sample with 30% filler content. Degradation tests revealed distinct differences in the degradation profile for composites due to the presence of filler. Composites with a lower biochar content displayed curling crack edges during hydrolytic degradation, and when the filler content reached 20 wt%, PLA loss accelerated. This study suggests that biochar-based composites have potential to be used as sustainable materials with improved properties.

摘要

昂贵的可生物降解聚合物的有趣替代品是它们与天然填料的复合材料。研究了将生物炭添加到聚乳酸（PLA）和聚（3-羟基丁酸酯-4-羟基丁酸酯）的共混物中，并对所得材料的性能及其在降解过程中的变化进行了评估。引入生物炭作为填料使静电性能有了显著改善。表面电阻率从不含生物炭的样品的3.80×10降低到填料含量为30%的样品的1.32×10。降解测试表明，由于填料的存在，复合材料的降解曲线存在明显差异。生物炭含量较低的复合材料在水解降解过程中显示出卷曲的裂纹边缘，当填料含量达到20 wt%时，PLA的损失加速。这项研究表明，基于生物炭的复合材料有潜力用作性能得到改善的可持续材料。
