Special Issue Information

Dear Colleagues,

Green chemistry and renewable natural resources have received considerable interest due to their compliance with environmental requirements as well as their possible applications.

Cellulose has demonstrated its utility in many fields; however, it does not possess the special characteristics needed for certain applications without further treatment. The pre-treatment of cellulosic materials can involve various techniques such as the use of enzymes, physical or chemical methods, dissolution, fractionation, etc. Native cellulose is scarcely used due to its strong hydrophilic nature, pure solubility, and high crystallinity. Hence, cellulose-based polymers (i.e., cellulose fibers, cellulose membranes, cellulose nanomaterials, or bacterial cellulose) have found a large spectrum of applications. They are either used as synthetized or chemically modified in different composite materials in order to improve or modify the properties of the final product for the desired application.

In recent years, the research community has demonstrated a great deal of interest in finding and using unconventional sources as well as more eco-friendly methods for the extraction and modification of cellulose and cellulose nanomaterials.

This Special Issue on “Advances in Cellulose-Based Polymers and Composites” is dedicated to the most recent research regarding the preparation, properties, and applications of cellulose-based polymers, as well as their use in different composite formulations.

Both original contributions and comprehensive reviews are welcome.

Abstract
Cellulose-based aerogel has attracted considerable attention for its excellent adsorption capacity, biodegradability, and renewability. However, it is considered eco-unfriendly due to defibrillation of agriculture waste and requires harmful/expensive chemical agents.

Cellulose-based aerogel has attracted considerable attention for its excellent adsorption capacity, biodegradability, and renewability. However, it is considered eco-unfriendly due to defibrillation of agriculture waste and requires harmful/expensive chemical agents. In this study, cornstalk rind-based aerogel was obtained via the following steps: green H2O2/HAc delignification of cornstalk rind to obtain cellulose fibers, binding with carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) and freeze-drying treatment, and hydrophobic modification with stearic acid. The obtained aerogel showed high compressive strength (200 KPa), which is apparently higher (about 32 kPa) than NaClO-delignified cornstalk-based cellulose/PVA aerogel. Characterization of the obtained aerogel through SEM, water contact angle, etc., showed high porosity (95%), low density (0.0198 g/cm−3), and hydrophobicity (water contact angle, 159°), resulting in excellent n-hexane adsorption capacity (35 g/g), higher (about 29.5 g/g) than NaClO-delignified cornstalk-based cellulose/PVA aerogel. The adsorbed oil was recovered by the extrusion method, and the aerogel showed excellent recyclability in oil adsorption. Full article
