摘要

Global warming caused by the environmental impact of the excessive use of materials and products from fossil fuels has influenced the need for new technologies and products from renewable sources. Agro-industrial wastes generated from various plant species provide the main raw material in the extraction of cellulose, this environmentally sustainable natural polymer possesses properties that make it a renewable and sustainable source of various materials for a wide variety of applications in different types of industry. Currently, the use of cellulose in the development of super absorbent hydrogels has been the subject of study, providing reinforcement, biocompatibility, non-toxicity and absorption properties. The hydrogel is a polymeric material that extends in three dimensions (3D), has a high absorption capacity due to its hydrophilic nature and the various crosslinking agents used in their synthesis processes. Crosslinking agents are the key to the attachment of functional groups through covalent bonds of the polymers, generating physical networks. Structural design and adsorption properties are responsible for their wide demand for developing a variety of materials in tissue engineering, wound dressings, drug delivery, membrane development for wastewater treatment, biosensors, catalysts and soil conditioning for various crops. For the aforementioned, this review presents the latest advances in the use of cellulose and nanocellulose from lignocellulosic waste as sustainable and versatile raw materials for the development of hydrogels; its potential use in a variety of applications is also discussed. The different sources, treatments, extraction methods and their main characteristics are exposed. Likewise, cellulose hydrogels, their classification, synthesis and cross-linking methods are presented, as well as the latest advances in cellulose hydrogels in the medical, food, agriculture and water treatment industries.
