MXenes as the next frontier: Innovative applications in food packaging

Abstract

Background

MXene, a family of two-dimensional (2D) transition metal carbides, nitrides, and carbonitrides, has attracted considerable attention due to its unique properties, including high electrical conductivity, mechanical strength, functional characteristics, and excellent barrier performance. In the food packaging industry, these properties present opportunities to improve packaging materials, extend shelf life, and ensure food safety.

Scope and approach

This review explores the innovative applications of MXene in food packaging, focusing on its potential to replace conventional materials. This review includes the synthesis of MXene, functionalization for improved properties, and the incorporation of MXene-based composites into food packaging solutions. This study also discusses the impact of MXene on the properties of packaging films and the applications of MXene-based packaging materials in active and smart packaging systems, highlighting ongoing research in this area.

Key findings and conclusions

MXene shows significant potential in food packaging due to its excellent mechanical properties and improved barrier properties against moisture, gas, and light. Some MXene compositions have natural antimicrobial properties, providing additional protection against spoilage and pathogens. Furthermore, when combined with biodegradable polymers, MXene composites can help alleviate environmental concerns associated with plastic waste. However, the commercialization of MXene-based packaging is hampered by challenges such as high production costs and regulatory restrictions. Nevertheless, MXene represents a revolutionary advance in food packaging technology and has the potential to achieve greener, safer, and more efficient food preservation solutions.
