Abstract

Polyurethanes (PUs) are extremely versatile materials used across different industries. Traditionally, they are synthesized by reacting polyols and isocyanates, both of which are petroleum-derived reagents. In response to the demand for more eco-friendly materials, research has increasingly focused on developing new routes for PU synthesis using renewable feedstocks. While substituting isocyanates remains a greater challenge, replacing fossil-based polyols with bio-based alternatives is now a promising strategy. This review explores the main natural sources and their transformations into bio-polyols, the incorporation of bio-fillers into PU formulations, and the production of non-isocyanate polyurethanes (NIPUs). Additionally, the study summarizes the growing body of research that has reported successful outcomes using bio-polyols in PU foams for distinct applications.

生物基聚氨酯泡沫:原料,合成和应用。
聚氨酯(pu)是一种用途广泛的材料,用于不同的行业。传统上,它们是通过多元醇和异氰酸酯反应合成的,两者都是石油衍生的试剂。为了响应对更环保材料的需求,研究越来越集中于开发使用可再生原料合成PU的新路线。虽然取代异氰酸酯仍然是一个更大的挑战,但用生物基替代品取代化石基多元醇现在是一个很有前途的策略。本文综述了主要的天然来源及其转化为生物多元醇,将生物填料掺入PU配方,以及非异氰酸酯聚氨酯(nipu)的生产。此外,该研究总结了越来越多的研究报告,这些研究报告成功地将PU泡沫中的生物多元醇用于不同的应用。

期刊介绍: Biomolecules (ISSN 2218-273X) is an international, peer-reviewed open access journal focusing on biogenic substances and their biological functions, structures, interactions with other molecules, and their microenvironment as well as biological systems. Biomolecules publishes reviews, regular research papers and short communications.  Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced.
