Abstract

Developing efficient multifunctional composite polymer materials with excellent flame retardency, electromagnetic interference (EMI) shielding, antibacterial and mechanical strength has been a huge challenge. Here, a nano nanofiller (Ag@PZS@MXene) was synthesized via electrostatic self-assembly and the nanofiller was introduced into ABS matrix to fabricate ABS nanocomposites (ABS-Ag@PZS@MXene). Then, multifunctional hierarchical structural composites ABS-Ag@PZS@MXene/MXene film (ABS-Ag@PZS@MXene/SW) was constructed via air-assisted thermocompression technology. The core–shell structure (Ag@PZS) protects the MXene from oxidation while effectively optimizing the interface between the multifunctional nanofiller and the ABS matrix. Consequently, the obtained hierarchical ABS composites have excellent flame resistance (reduction in peak heat release rate of 36.8 % and peak smoke production rate of 39.1 %) outstanding electromagnetic shielding performance (the EMI SE reached 25.2 dB at 12.4 GHz), superior antibacterial activity and improved mechanical performance. This work supplies a feasible strategy for designing polymer-based composite with excellent multifunctionality, which have a great potential for applications in many fields.

期刊介绍： Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
