Doctoral student Jun Chen and colleagues in our team, under the supervision of Professor Wei Chen, investigated the structural regulation and performance optimization of waterborne PVA adhesives for polarizers. The related work was published in Langmuir. By introducing Zn2+ coordination into an acetoacetylated poly(vinyl alcohol) (AAPVA) system, the study constructed a synergistic multinetwork structure that effectively enhanced interfacial adhesion, cohesive strength, and hydrothermal resistance of the adhesive.
The results showed that, under optimized conditions, the average peel strength of the adhesive increased from 2.68 × 10−2 N·mm−1 to 9.32 × 10−2 N·mm−1, while excellent stability under hydrothermal aging was also achieved. This work provides a new strategy for the design of high-performance waterborne adhesives for polarizers.
