Research and Application Progress of Carboxymethyl Cellulose Based Composite Hydrogels
Carboxymethyl cellulose(CMC)hydrogel is a kind of hydrophilic natural three-dimensional polymer material with high water absorption.Therefore,the hydrogel prepared with sodium carboxymethyl cellulose is safe,non-toxic and biodegradable.It is widely used in medicine,food,agriculture,environment and other fields as a fresh-keeping material,antibacterial material,biosensor,drug delivery system and adsorbent for removing heavy metals.In this paper,according to the different sources of CMC composite hydrogel materials,the research progress,functional characteristics and application fields of macromolecular/CMC hydrogel,monomer/CMC hydrogel and inorganic/CMC hydrogel are reviewed in classification,which provides some ideas and theoretical basis for the research of carboxymethyl cellulose composite hydrogel.The improvement of carboxymethyl cellulose composite hydrogel performance by different materials in this direction was summarized,and the application prospect of carboxymethyl cellulose hydrogel was prospected.
