Cellulose: a comprehensive review of its properties and applications
| Resumo: | Cellulose is a complex carbohydrate and a fundamental structural element in plant cell walls, consisting of long chains of glucose molecules that form a rigid framework providing strength and support to plants. As the most prevalent natural polymer, cellulose is an ideal candidate for producing environmentally friendly and economically viable polymeric products, traditionally made from petroleum-based synthetic polymers. It is the most abundant renewable material in the biosphere, cost-effective, non-toxic, and biodegradable. Cellulose’s physical and chemical properties – such as its insolubility in water, semi-crystalline structure, high tensile strength, biodegradability, and chemical reactivity – make it an incredibly versatile material. Recent studies have demonstrated its promising applications in various industries, including biofuels, bioplastics, and eco-conscious packaging. Specifically, cellulose acetate has emerged as a widely used derivative due to its biodegradable nature and versatility in applications like 3D printing, medical supplies, and environmentally friendly packaging. However, challenges related to extraction costs, property variability, and competition with synthetic materials still exist. Future research will aim to overcome these barriers by enhancing the properties of cellulose, improving processing technologies, and exploring nanocellulose and genetically modified plants as key areas for innovation. Innovations in cellulose recycling and the use of agricultural waste for biofuels are expected to further drive its integration into circular economy models, fostering environmental benefits and reducing overall impact. |
