Complex Dielectric Properties of Modified Polyhydroxybutyrate

聚羟基丁酸酯(PHB)是微生物发酵产生的一种可再生生物聚合物。海流 PHB衍生材料面临的挑战包括找到一种可以取代当前 以石油为基础的商品聚合物。鉴于食品包装和生物医学应用已经 建议作为合适的应用，将应用多样化到大量应用可以显著 提振生物聚合物生产产业。最近，PHB衍生材料表现出几乎恒定的 在很宽的频率范围(0.01-10E+7赫兹)上的介质损耗行为，表明PHB可以是一个 令人信服的宽带电容器材料。在这里，我们将调查处理/属性关系 改性PHB材料。具体地说，我们将研究复杂的介电性能和机械性能。

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.
