Abstract

Leather is one of the most popular products across globe and holds a significant place in the economy, while the pollution, associated to traditional leather industry, is far away on the “green chemistry” principles. In this sense, polyurethanes, which exhibit tunable chemical structures by selecting suitable precursors, can fit specific requirements, and the developments of green strategies make them important candidates for leather industry. This mini review briefly outlines the recent development of conventional (petrol-based) and sustainable polyurethanes in the leather industry, including their design and properties, in applications such as synthetic leather and surface-finishing (coatings/binders). Finally, outlooks of the future tendency, including more environmental-friendly strategies, bio-sourced/recycled materials and development of high-value multifunctional leather materials, are also here proposed.

聚氨酯皮革应用的最新进展:传统和绿色解决方案概述

皮革是全球最受欢迎的产品之一，在经济中占有重要地位，而与传统皮革工业相关的污染与“绿色化学”原则相去甚远。从这个意义上说，聚氨酯通过选择合适的前体，表现出可调节的化学结构，可以满足特定的要求，绿色战略的发展使其成为皮革工业的重要候选者。本文简要概述了传统聚氨酯(汽油基)和可持续聚氨酯在皮革工业中的最新发展，包括它们的设计和性能，在合成革和表面整理(涂料/粘合剂)等应用中的应用。最后，展望了未来的发展趋势，包括更环保的策略、生物源/再生材料和高价值多功能皮革材料的发展。图形抽象
