To address this issue, this study investigates the interfacial bonding behavior of multi-material structures composed of acrylonitrile butadiene styrene (ABS) and polyamide (PA), two polymers that are chemically incompatible. To enhance interfacial adhesion, three commonly used thermoplastic filaments were employed as intermediate compatibilizing layers. Mechanical characterization was performed through tensile and interlaminar shear strength tests to evaluate bonding performance. All compatibilizing layers improved adhesion between ABS and PA, yielding up to 32% higher tensile strength and 43% higher interlaminar shear strength compared to direct stacking. Fractographic observations confirmed these results by revealing distinct failure patterns and improved interfacial continuity. Overall, the findings demonstrate a practical method for achieving strong adhesion between incompatible polymers without surface treatments or adhesives, offering guidance for the design of hybrid structures and expanding the potential of the technology.</p>\u0000 </div>","PeriodicalId":17662,"journal":{"name":"Journal of Vinyl & Additive Technology","volume":"32 2","pages":"484-498"},"PeriodicalIF":3.6,"publicationDate":"2026-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, polymer-based nanocomposites have drawn significant interest due to their affordability, ease of processing, and diverse applications. Specifically, Polymer/Zinc Oxide (ZnO) nanocomposites have emerged as promising materials due to their enhanced mechanical and thermal behavior, as well as improved durability of the polymer when exposed to UV radiation. With the broad band gap and strong capacity for UV absorption, ZnO effectively minimizes UV transmission, making it suitable for use in packaging materials, textiles, coatings, and protective gear. This review outlines the advancements in UV-blocking effectiveness of Polymer/ZnO nanocomposites, focusing on the synthesis conditions and size of ZnO. It discusses essential factors for efficient UV-shielding, including the synthesis and dispersion of ZnO within polymer matrices. The review encompasses synthetic polymers, biopolymers, polymeric blends, and copolymers to assess the effectiveness of ZnO as a UV-shielding material.
