Degradable Biopolymer-Based Nanocomposites in Water Treatment and Air Purification: A Review
Hani Nasser Abdelhamid
Abstract
This review explores degradable biopolymer-based nanocomposites and their diverse applications including water purification, environmental remediation, and air purification. It highlights the key trends and developments in biopolymers, such as cellulose and chitosan. These biopolymers can be functionalized or conjugated with advanced materials, such as metallic nanoparticles, metal oxides, zeolites, perovskites, covalent organic frameworks (COFs), metal–organic frameworks (MOFs), zeolitic imidazolate frameworks (ZIFs), and MXenes. The resulting biopolymer/nanoparticle composites exhibit remarkable multifunctional properties, making them highly suitable for industrial-scale production and integration into modern technologies. Nanocellulose is a promising material for enabling advanced fabrication techniques, such as integrating MOFs into commercial products via three-dimensional (3D) printing and paper-forming techniques. This review highlights these materials’ potential to revolutionize sustainability and green technology applications, offering innovative solutions for critical challenges in various sectors.
