Abstract

The preparation of the polyimine (PI) networks from renewable feedstocks has attracted increasing attention due to the degradability and self-healing capabilities of PI networks, which contribute to sustainable development. However, most of bio-based PI networks possess poor environmental stability and mechanical strength. Herein, natural peach gum w·as employed to construct water-resistant bio-based PI networks with high performances, by the curing reaction of Schiff base between 4-aminobenzoic acid grafted peach gum polysaccharide and vanillin-derived difunctionalized aldehyde. The resultant polyimine networks (PGBV) exhibit high tensile strength and high Young’s modulus, due to their unique network structures. Moreover, PGBV-100 demonstrates excellent hydrophobicity, welding, self-healing and reprocessing abilities. Furthermore, PGBV-100 can completely degrade in an aqueous solution of HCl (0.1 M), enabling closed-loop recycling. In this work, a research strategy for constructing bio-based PI networks with high performances is presented and the resultant PGBV networks show promising potential application as materials for transportation and building materials.

桃胶基聚酰亚胺网络具有防水、高强度和可回收的性能

由于聚酰亚胺（PI）网络具有可降解性和自愈能力，有助于可持续发展，因此利用可再生原料制备聚酰亚胺（PI）网络日益受到关注。然而，大多数生物基 PI 网络的环境稳定性和机械强度较差。本文利用天然桃胶，通过 4-aminobenzoic acid 接枝桃胶多糖与香兰素衍生的双官能团醛之间的希夫碱固化反应，构建了具有高性能的防水生物基 PI 网络。由于其独特的网络结构，生成的聚亚胺网络（PGBV）具有很高的拉伸强度和杨氏模量。此外，PGBV-100 还具有出色的疏水性、焊接性、自愈性和再加工能力。此外，PGBV-100 还能在盐酸（0.1 M）水溶液中完全降解，从而实现闭环回收。本研究提出了一种构建高性能生物基 PI 网络的研究策略，所得到的 PGBV 网络作为运输和建筑材料的材料具有广阔的应用前景。
