摘要

聚己二酸-对苯二甲酸丁二醇酯(PBAT)是一类兼具优异柔韧性和可加工性的可生物降解聚酯，但其力学强度不足，限制了更广泛的应用. 本研究通过扩链法将磺酸钠盐基团(SS)引入到含丰富

结构的PBAT链段中，制备得到PBATSS离聚物. 利用链段间静电作用、阳离子-

以及氢键相互作用的协同效应，显著提升了材料的力学性能及熔体强度. 共聚物保持良好的结晶性和宽熔程(Δ

30 ℃)，使其具备呈现形状记忆效应的必要条件. PBATSS1在120 ℃下编程，其形状固定率和回复率分别达到96.7%和93.3%. 该材料还具有良好的热加工性，通过3D打印制备“蝴蝶”模型，并展现出多形态可逆变形与回复能力. 本研究为PBAT基材料的高性能及多功能化提供了一种新的分子设计策略.

Abstract

Poly(butylene adipat

-terephthalate) (PBAT) is a biodegradable polyester with excellent flexibility and processability

yet its relatively low mechanical strength limits broader applications. In this study

sodium sulfonate (SS) groups were introduced into the

-rich PBAT chains

via

coupling strategy to prepare PBATSS ionomers. The synergistic interactions of intermolecular hydrogen bonding and sulfonate anion-sodium cation-

interactions effectively enhanced the mechanical properties of the copolymers. The PBATSS series maintained desirable crystallinity and exhibited a broad melting range (Δ

30 ℃)

providing the thermal prerequisites for shape memory behavior. Notably

PBATSS1 exhibited outstanding shape memory effect at a programming temperature of 120 ℃

achieving a

of 96.7% and a

of 93.3%. In addition

PBATSS demonstrated excellent thermal processability

enabling the fabrication of a 3D-printed "butterfly" model that exhibited programmable multi-shape deformation and recovery. This study offers a new strategy for the development of high-performance and multifunctional biodegradable materials.
