State of the art in preparation and application of hemicellulose-based hydrogels
摘要
Abstract
In recent years,with the continuous advancement of biomass refining technology and materials science,the use of biodegradable and renewable lignocellulosic resources to develop environmentally friendly hydrogel materials has gradually become a hot topic in both academic and industrial fields.Hemicellulose,one of the main components of lignocellulosic fibers,is a renewable polysaccharide,second only to cellulose on land.On the one hand,hemicellulose possesses the advantages of wide source,low cost,good biocompatibility,biodegradability,etc.On the other hand,it also contains a large number of hydrophilic oxygen-containing groups,which are highly branched,hydrophilic,easy to be modified,and endowed with many excellent properties of hydrogel materials.Thus,with the global targets of carbon emission peak reduction and carbon neutrality,hemicellulose is an ideal choice for the fabrication of advanced hydrogel materials.As natural polymer materials with a three-dimensional network structure,hemicellulose-based hydrogels have been attracting attention in the field of multifunctional materials due to the excellent water retention,safety,nontoxicity,biodegradability,ease of chemical modification and other unique properties.As a result,based on its structural characteristics,hemicellulose-based hydrogels have a broad application prospect in the fields of biomedicine,conductive sensor and environmental protection,and they are expected to replace the traditional petroleum-based hydrogels materials.This study primarily reviews research progress on hemicellulose-based hydrogels.It begins with an overview of the types,structures,properties and extraction methods of hemicellulose.Then,it systematically summarizes the preparation methods including both physical and chemical cross-linking,along with the formation mechanism and application properties of hemicellulose-based hydrogels.Moreover,the latest application progress of hemicellulose-based hydrogels in the fields of efficient adsorption and purification,controlled release of drugs,tissue engineering scaffolds,conductive sensor,and 3D printing is also highlighted.Finally,this study summarizes the challenges and issues in the development and application of hemicellulose-based hydrogels,while also discussing future development trends and research directions.In particular,further in-depth research is recommended on:clean and efficient methods for the extraction of hemicellulose;the development of environmentally friendly preparation processes for hemicellulose-based hydrogels;and the expansion of their application fields,all with the goal of facilitating industrial-scale utilization.It is expected that the summary and review will provide valuable theoretical insights for the design and development of advanced,multifunctional hemicellulose-based materials with excellent performance.关键词
