Special Issue Information

Dear Colleagues,

Cellulose is a polysaccharide that is the most abundant natural polymer on earth and has remarkable properties. Cellulose has attracted attention due to its renewability, wide availability, low cost, biocompatibility and biodegradability, etc. The biodegradability of cellulose-based materials in soil and oceans could reduce environmental pollution. This makes cellulose one of the promising renewable resources for many applications including packaging, paper, clothes, cosmetics and pharmaceuticals. This Special Issue is focused on reporting the most current research on cellulose-based materials and film, which includes the preparation and modifications of all cellulose-based materials, and the new preparation and processing methods to develop new cellulose-based composites or films, characterization techniques, properties and applications.

For this Special Issue, authors are welcome to submit both articles and review papers.

(i) Original research/review articles concerning the new experimental research and knowledge in preparation or processing of cellulose-based materials and films.

(ii) Original research/review articles concerning developments of multi-functional cellulose materials and film.

(iii) Original research/review articles concerning cellulose materials and film for new applications.

(iv) Original research/review articles concerning new “Green” methods for the preparation of environmentally friendly cellulose materials and cellulose film.

This work reports on the structural modification of cellulosic materials with magnetic iron oxide nanoparticles through the co-precipitation method. Cellulose is one of the most abundant natural polymers with chemical variability brought about by the presence of several hydroxyl groups, allowing its surface modifications through the insertion of several chemical groups to impact its cellulosic characteristics. Thus, the objective of this study was to synthesize magnetic iron oxide nanoparticles (MNPs) through co-precipitation, followed by in situ incorporation of MNPs onto chemically purified cellulose (CPC) and cellulose nanocrystals (CNC). The composites were characterized for thermal properties using TGA, molecular structure using FTIR, surface morphology using SEM, elemental composition using electron dispersion spectroscopy (EDS), and crystallinity using XRD. The prepared composites presented improved crystal, thermal, and surface properties. CNC-MNPs and CPC-MNPs bore particle sizes of 26.94 and 37.72 nm, respectively, whereas MNPs’ particle size was 10.3 nm. EDS analysis indicated that Fe, C, and Cl were the main elements present in the composites. Surface modification of the cellulosic materials presented excellent sorption surface properties and can be used in several industrial processes, such as wastewater purification, air filtration, and various environmental remediation processes.

Lyocell fiber has emerged as a new generation of green fiber due to its preparation process and unique properties in comparison with viscose fiber. The raw material for the preparation of Lyocell fiber has a great impact on the quality of the finished product. However, unlike viscose-grade dissolving pulp, there is no evaluation system for Lyocell-grade dissolving pulp, making it difficult to assess the quality of the raw material. This study examined the approach to upgrade the paper-grade pulp to dissolving pulp for the preparation of the raw material for Lyocell fiber. Under the sequence of caustic extraction, acid treatment, and enzymatic treatment, the pulp was prepared with competitive properties compared to the commercial Lyocell-grade dissolving pulp. The assessment of prepared pulp was also accomplished by characterizing the pulp properties, the dissolution properties, and the spinnability and stability of Lyocell solution using the prepared sample. In addition, the dissolution mechanism and influencing factors of pulp in the system were elucidated, providing a theoretical basis for upgrading paper-grade pulp to dissolving pulp for Lyocell fiber production.
