| Aerogels are unique materials that possess extraordinary properties such as high porosity, low density, and excellent mechanical, thermal and acoustic insulation properties. They have been widely researched for various applications due to their exceptional features. Aerogels composed of chitosan (CS), polyvinyl alcohol (PVA) and graphene oxide (GO) are a recent development and have garnered significant attention due to their exceptional properties. Chitosan (CS) is a biopolymer derived from chitin, which is a natural polymer found in the exoskeleton of crustaceans and insects. It has excellent antibacterial properties and is biodegradable. Polyvinyl alcohol (PVA) is a synthetic water-soluble polymer that is known for its high tensile and mechanical strength. Graphene oxide (GO) is a twodimensional material that has exceptional mechanical, thermal, and electrical properties. When combined, these materials result in an aerogel with exceptional properties that can be used in various applications. These aerogels can be used as a catalyst support, drug delivery systems, thermal insulation materials, sensors, and in energy storage systems. They are also used in aerospace and automotive industries due to their lightweight and high strength-to-weight ratio. Moreover, they are environmentally friendly and biodegradable, making them ideal for various sustainable applications. One of the main advantages of incorporating graphene oxide (GO) as a reinforcement into aerogels is its high surface area and ability to enhance mechanical properties. Graphene oxide (GO) can also facilitate the dispersion of chitosan (CS) and polyvinyl alcohol (PVA) in the aerogel matrix due to its strong interaction with the polymers, thus improving the stability and performance of the aerogel. The importance of aerogels composed of chitosan (CS), polyvinyl alcohol (PVA), and graphene oxide (GO) lies in their unique properties and the diverse range of potential applications they offer in various fields such as medicine, construction, and industry, leading to the development of more eco-friendly and sustainable technologies. | |
