Abstract

Polyhydroxyalkanoates (PHA) envisage a potential biomaterial alternative to replacing synthetic polymers for their biodegradability and biocompatibility. Modification approaches exploit the attributes and adjust the intrinsic hydrophobic properties, such as blending to produce a new polymer mix with novel properties. Functionalization of PHA, especially chemical grafting, perform to introduce additional compounds covalently to PHA. As these methods address PHA potential and enable extensive utilization as a responsive material, reports are readily available in academia as confirmation. There are also substantial responsive PHA-based material applications in the biomedical area and agriculture materials, packaging materials, and nanocomposite materials.

摘要

聚羟基链烷酸酯 (PHA) 设想了一种潜在的生物材料替代品，以替代合成聚合物的生物降解性和生物相容性。改性方法利用这些属性并调整固有的疏水特性，例如混合以产生具有新特性的新聚合物混合物。PHA 的功能化，尤其是化学接枝，用于将其他化合物共价引入 PHA。由于这些方法解决了 PHA 的潜力并能够广泛用作响应材料，因此学术界很容易获得报告作为确认。在生物医学领域和农业材料、包装材料和纳米复合材料中也有大量响应性 PHA 材料应用。
