Natural Polymer-Based Aerogels for Filtration Applications

Environmentally friendly, biopolymer-based aerogel has been developed to become one of the most potentially utilized materials in different water purification applications. The biopolymer-based aerogel has distinct physical, chemical, and mechanical properties that are used in the removal of organic molecules, the extraction of organic solvents, the separation of oil and water, the solar-driven evaporation of water, the separation of heavy metal ions, and pharmaceutical industries. Today’s biopolymer aerogel discipline is being advanced by empirical material discovery at the micro scale, but to narrow the market gap, a more solid theoretical foundation and pilot projects are needed. In this study, the use of biopolymer-based aerogels for separation applications is critically examined. The analysis demonstrates the connection between their characteristics and how they are used in the healing of wounds. Additionally, the potentials, difficulties, and application of biopolymer-based aerogels are highlighted.
