Special Issue Information

Dear Colleagues,

Biopolymer-based materials are, in general, environmentally friendly materials, which can be obtained from renewable sources. Following a circular economy principle, cellulose can be obtained from biomass residues from forests or crop production. Cellulose, being the most abundant biopolymer on the planet, is an obvious choice to produce materials with favourable properties for a wide range of applications, such as biomedical applications, environmental applications, food packaging and electronic devices, thus being a logical substitute to petroleum-based polymers, especially plastics. Cellulose is also a remarkable starting material for chemical modification, due to the large available hydroxyl groups in its structure. Thus, the preparation of water-soluble cellulose derivatives is suitable as rheology modifiers, flocculants, etc., depending on the derivatization introduced. The derivatization can be carried out via different methods, leading to partially or fully dissolved cellulose. Other important classes of cellulosic materials are nanocelluloses (cellulose nanocrystals (CNC), cellulose nanofibrils (CNF) and bacterial cellulose (BC)). This class of biobased nanomaterials possesses outstanding properties and finds application in multiple areas.

In this Special Issue, the objective is to bring together recent advances in the field of cellulose-based materials, including the use of different cellulosic materials, wastes valorisation, preparation procedures, and application in different fields, including industrial application.

Nanocellulose fiber materials were considered promising biomaterials due to their excellent biodegradability, biocompatibility, high hydrophilicity, and cost-effectiveness. However, their low proton conductivity significantly limited their application as proton exchange membranes. The methods previously reported to increase their proton conductivity often introduced non-biodegradable groups and compounds, which resulted in the loss of the basic advantages of this natural polymer in terms of biodegradability. In this work, a green and sustainable strategy was developed to prepare cellulose-based proton exchange membranes that could simultaneously meet sustainability and high-performance criteria. Adenine and thymine were introduced onto the surface of tempo-oxidized nanocellulose fibers (TOCNF) to provide many transition sites for proton conduction. Once modified, the proton conductivity of the TOCNF membrane increased by 31.2 times compared to the original membrane, with a specific surface area that had risen from 6.1 m²/g to 86.5 m²/g. The wet strength also increased. This study paved a new path for the preparation of environmentally friendly membrane materials that could replace the commonly used non-degradable ones, highlighting the potential of nanocellulose fiber membrane materials in sustainable applications such as fuel cells, supercapacitors, and solid-state batteries.

The oxidation of cellulose to dialdehyde cellulose (DAC) is a process that has received increased interest during recent years. Herein, kinetic modeling of the reaction with sodium periodate as an oxidizing agent was performed to quantify rate-limiting steps and overall kinetics of the cellulose oxidation reaction. Considering a pseudo-first-order reaction, a general rate expression was derived to elucidate the impact of pH, periodate concentration, and temperature on the oxidation of cellulose and concurrent formation of cellulose degradation products. Experimental concentration profiles were utilized to determine the rate constants for the formation of DAC (k1), degradation constant of cellulose (k2), and degradation of DAC (k3), confirming that the oxidation follows a pseudo-first-order reaction. Notably, the increase in temperature has a more pronounced effect on k1 compared to the influence of IO4− concentration. In contrast, k2 and k3 display minimal changes in response to IO4− concentration but increase significantly with increasing temperature. The kinetic model developed may help with understanding the rate-limiting steps and overall kinetics of the cellulose oxidation reaction, providing valuable information for optimizing the process toward a faster reaction with higher yield of the target product.
