“…In recent research on ACCs, the focus has often been on the development of multifunctional films [ 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ]. However, more investigation is needed into constructive laminates, bulk materials, and how different raw material choices and process conditions play a part in the properties of structured materials.…”

All-cellulose composites (ACCs) are manufactured using only cellulose as a raw material. Biobased materials are more sustainable alternatives to the petroleum-based composites that are used in many technical and life-science applications. In this study, an aquatic NaOH-urea solvent system was used to produce sustainable ACCs from wood-based woven textiles with and without the addition of TEMPO-oxidized nanocellulose (at 1 wt.-%). This study investigated the effects of dissolution time, temperature during hot press, and the addition of TEMPO-oxidized nanocellulose on the mechanical and thermal properties of the composites. The results showed a significant change in the tensile properties of the layered textile composite at dissolution times of 30 s and 1 min, while ACC elongation was the highest after 2 and 5 min. Changes in hot press temperature from 70 °C to 150 °C had a significant effect: with an increase in hot press temperature, the tensile strength increased and the elongation at break decreased. Incorporating TEMPO-oxidized nanocellulose into the interface of textile layers before partial dissolution improved tensile strength and, even more markedly, the elongation at break. According to thermal analyses, textile-based ACCs have a higher storage modulus (0.6 GPa) and thermal stabilization than ACCs with nanocellulose additives. This study highlights the important roles of process conditions and raw material characteristics on the structure and properties of ACCs.

“…Traditional characterization analysis of cellulose or cellulosic composites generally depends on X-ray diffraction (XRD), Fourier transformation infrared (FT-IR) spectroscopy, and scanning electron microscopy (SEM). In addition, it is possible to combine the data explored by new methods (Raman and X-ray photoelectron (XPS) spectroscopies) at the same time (Duchemin et al 2009(Duchemin et al , 2016Montoya-Rojo et al 2021).…”

As a consequence of increasingly serious environmental problems, many researchers are highlighting biomass materials. Cellulose, the most abundant bioresource, is becoming a key consideration for alleviating environmental pollution. Characterization of cellulosic materials is fundamental to exploring their structures and elemental contents. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) are frequently employed to study the structure of cellulose. Thus, it is urgent to combine traditional means with new ones. This study focused on the characterization of the all-cellulose composites (ACCs) model prepared via partially dissolving filter paper using 40% benzyltrimethylammonium hydroxide (BzMe3NOH) aqueous solution. Characterized by SEM, XRD, Fourier transformation infrared spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy, the unique transformation from cellulose I to cellulose II of the ACCs model was explored. These characterization methods exhibited respective features, which could be universal ways to investigate ACCs.

In the 1960s, the Swedish company Celloplast patented the first one‐piece plastic bag for packaging, and such plastic bags are heavily used all around the world until they are banned by some countries for environmental and sustainability reasons. Similarly, the EU banned certain single‐use plastic items in 2021—but food packaging is not part of this new regulation. And indeed, the majority of food packaging encountered today in the supermarket is still made from traditional, petrol‐based plastics. This review summarizes recent efforts in developing more sustainable alternatives to such petrol‐based food packaging. Different natural sources and production processes used to develop biodegradable, biopolymer‐based materials (bbMs) are discussed, which are categorized into natural bbMs, modified/plasticized bbMs, and plastic bbMs. An overview of the material properties of commercially available bbMs and bbMs developed in academic research projects is provided, and are compared with the properties of conventional, petrol‐based materials used for packaging. Furthermore, the role of academic and industrial contributors along the value chain of bbMs is highlighted and challenges that are responsible for the still limited occurrence of bbMs in daily lives are discussed.
