Versions Notes

Cellulose is the most abundant renewable biopolymer in nature, being the main constituent of plant cell walls [1]. Nanocellulose is a new class of biomaterial, with numerous biomedical applications due to its unique properties, such as biocompatibility, biodegradability, and good mechanical properties [2]. This study aimed to obtain 3D porous structures based on nanocellulose and PEG-based monomers/oligomers.
The obtained grafted cellulose aerogels were characterized by Brunauer-Emmett-TellerBET surface area analysis to observe the increased porosity and high specific area. Grafting of cellulose nanofibers is seen in the modification of the FT-IR spectrum by the appearance of new peaks and bands with high intensity. Due to these properties, the obtained cellulose composite aerogels (Figure 1) can be potentially used as scaffolds for tissue regeneration or as drug delivery systems.
