摘要

本研究提出了一种利用云杉木质素制备高性能压敏胶（psa）的新方法。通过木质素优先策略，木质素被选择性地解聚成4-丙醇拴系愈创木酚，然后进行胺化、丙烯酰胺化和与丙烯酸正丁酯（BA）共聚生成聚合物材料。由此得到的木质素衍生的psa具有优异的机械性能，剥离强度高达4.4 N cm-1，粘性强度高达3.9 N cm-1，超过了一些商业产品。这项工作为可持续的高性能PSA解决方案提供了一条独特的途径，以满足不断增长的工业需求。

Fabricating Robust Pressure-Sensitive Adhesives from Lignin Depolymerization-Derived 4-Propanol-Tethered Guaiacol.

This study presents a novel approach for fabricating high-performance pressure-sensitive adhesives (PSAs) using spruce tree lignin. Through a lignin-first strategy, lignin is selectively depolymerized into 4-propanol-tethered guaiacol, followed by amination, acrylamidation, and copolymerization with n-butyl acrylate (BA) to generate polymeric materials. The resulting lignin-derived PSAs exhibit excellent mechanical properties, achieving a peel strength of up to 4.4 N cm^-1 and a tack strength of up to 3.9 N cm^-1, surpassing those of several commercial products. This work provides a unique pathway to sustainable, high-performance PSA solutions to meet growing industrial demand.
