Polyhydroxybutyrate (PHB) is a renewable biopolymer obtained from microbial fermentation. The current challenge of PHB derived materials includes finding a 'killer application' that can substitute the current petroleum-based commodity polymers. Whereas food packaging and biomedical applications have been suggested as suitable applications, diversifying the application to large-quantity application can significantly boost the biopolymer production industry. Recently, PHB-derived material exhibited a nearly constant dielectric loss behavior over a broad frequency range (0.01 - 10e+7 Hz), suggesting that PHB can be a compelling material for broadband capacitors. Here, we will investigate processing/property relationship of modified PHB materials. Specifically, we will study complex dielectric properties and mechanical properties.

聚羟基丁酸酯（Polyhydroxybutyrate，简称PHB）是一种由微生物发酵得到的可再生生物聚合物。当前 PHB衍生材料面临的挑战包括找到一种可以替代现有材料的“杀手级应用”， 石油基商品聚合物。尽管食品包装和生物医学应用一直是 建议作为合适的应用程序，多样化的应用程序，以大量的应用程序可以显着 促进生物聚合物生产行业。最近，聚羟基丁酸衍生的材料表现出几乎恒定的 在宽频率范围（0.01 - 10 e +7 Hz）内的介电损耗行为，表明PHB可以是一种 宽带电容器的引人注目的材料。在这里，我们将研究处理/属性关系， 改性聚羟基丁酸酯材料。具体来说，我们将研究复杂的介电性能和机械性能。
