The effect of the uniaxial tension and heat treatment on the CNY's physical and mechanical properties was investigated using SEM, DSC, FTIR, Raman, and tensile mechanical testing. The findings demonstrate a significant improvement in tensile strength and modulus, increasing from 5.38 ± 1.41 to 40.48 ± 4.74 MPa and from 27 ± 6.11 to 297.15 ± 68.29 MPa, respectively. This represents a 659% improvement in tensile strength and a nearly 1000% increase in modulus, highlighting the efficacy of the method. Compared to previous studies, this work introduces a low-temperature, scalable, and energy-efficient process that significantly enhances the mechanical properties, positioning it as an ideal candidate for applications in wearable electronics, energy storage, and advanced composite materials.

However, their complex chemical composition and strong interlayer adhesion—due to the presence of tie layers pose significant recycling challenges. This review explores waste management technologies for these complex films, including physical recycling (mechanical recycling, delamination, and selective dissolution-precipitation) and chemical recycling (pyrolysis, gasification, and depolymerization). Among them, mechanical recycling is the least energy-intensive and most environmentally friendly but is hindered by polymer degradation. Delamination, the least impactful solvent-based method, offers advantages, while selective dissolution-precipitation achieves high polymer purity but has a substantial environmental footprint due to excessive solvent use. Chemical recycling, though highly energy-intensive, produces derivatives with purity comparable to virgin materials. Therefore, the recent insights into each recycling process and their main scientific and technological challenges are summarized and discussed. Furthermore, life cycle assessment (LCA) studies on multilayer film waste management are reviewed. One proposed eco-design strategy involves transitioning from multi-material to mono-material multilayer films, offering a promising path toward sustainable management.</p>","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400414","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
