A bionanocomposite is a material that combines a biopolymer matrix with nanoscale reinforcements. It is a type of composite material that incorporates nanoparticles or nanofillers into a biopolymer matrix, resulting in enhanced mechanical, thermal, and barrier properties.
The biopolymer matrix can be derived from natural sources such as cellulose, chitosan, starch, or proteins. These biopolymers provide the structural integrity and flexibility to the composite material. The nanoscale reinforcements can include various types of nanoparticles such as carbon nanotubes, graphene oxide, metal nanoparticles, or clay nanoparticles.
The incorporation of nanoscale reinforcements into the biopolymer matrix improves the overall performance of the bionanocomposite. It can enhance mechanical properties like strength and toughness, increase thermal stability and flame resistance, improve barrier properties against gases and liquids, and provide antimicrobial or antioxidant functionalities.
Bionanocomposites have gained significant attention in various fields including packaging materials, biomedical applications, electronics, energy storage devices, and environmental remediation. They offer a sustainable alternative to conventional composite materials by utilizing renewable resources and reducing environmental impact.
