Abstract

Biofoam products have attracted considerable attention lately because there is a growing demand for green/sustainable products. To this end, various biobased foams have either been developed or are currently in development, e.g., bio-based polyurethanes (PUs), polylactic acid (PLA), starch, and polyhydroxyalkanotates (PHAs). Indeed, significant progress has been made; however, challenges still persist, for example, biobased foam products have poor processability, inferior compatibility, thermal and strength properties. In this review, we focus on five biofoam products: namely bio-based PUs, PLA, starch, PHAs, and cellulose biofoam products, along with their properties and performance, as well as their manufacturing processes. Further efforts are still needed to unlock the full potential of these bio-based products and meet the goal of complementing and gradually replacing some of their fossil-based counterparts. Finally, the challenges, as well as arising opportunities of future research directions are discussed.

生物基泡沫的起始材料、工艺和特性：综述

由于人们对绿色/可持续产品的需求日益增长，生物泡沫产品近来引起了广泛关注。为此，已经开发或正在开发各种生物基泡沫，例如生物基聚氨酯（PUs）、聚乳酸（PLA）、淀粉和聚羟基烷酸酯（PHAs）。事实上，生物基泡沫产品已经取得了重大进展，但挑战依然存在，例如，生物基泡沫产品的加工性差、兼容性低、热性能和强度低。在本综述中，我们重点介绍了五种生物泡沫产品：即生物基聚氨酯、聚乳酸、淀粉、PHAs 和纤维素生物泡沫产品，以及它们的特性和性能及其制造工艺。要充分挖掘这些生物基产品的潜力，实现补充并逐步取代部分化石基产品的目标，仍需进一步努力。最后，还讨论了未来研究方向所面临的挑战和机遇。
