“…Four main diffraction peaks located at 14.7, 16.5, 22.8 and 26.7 o could be observed in the WXRD patterns of tunic (Fig. S4a), re ecting the crystalline peaks of cellulose and the residual sand grain (Quero et al 2018). For tunicate cellulose lm, only three typical crystalline peaks at 14.7, 16.5, and 22.8 o were observed, corresponding to the ( 10), ( 110), and ( 200) crystal planes of cellulose I, respectively (Zhao and Li 2014).…”

“…However, these woodderived cellulose materials were obtained by deligni cation and a multitude of further processing steps, because the tight association of cellulose, hemicellulose, and lignin resulted that lignin could not be selectively removed from the cell wall of wood by chemical treatment (Keplinger et al 2020). Unlike wood, tunicate is a kind of sea animal with unique integumentary tissue (tunic) that were composed of crystalline cellulose embedded with protein, lipids, sulfated glycan and mucopolysaccharides (Quero et al 2018;Zhao and Li 2014). After removal of protein and other components, tunicate cellulose exhibited larger molecular weight, higher crystallinity (I b ), better thermal stability and higher modulus (143 GPa) in comparison with plant cellulose (Cheng et al 2017;Cheng et al 2018;.…”

Owing to non-degradable waste plastics caused serious environmental pollution, development of natural polymeric materials has become an important topic. Herein, multilayer tunicate cellulose lms (MTCFs) were fabricated by a top-down approach, where the alkali treated mantles of tunicate were layer-by-layer hot-pressed. Strong hydrogen bonds that formed between tunicate cellulose layers resulted in good interfacial compatibility of multilayer lms. The as-prepared MTCFs exhibited improved thermal stabilities, excellent mechanical properties, and good degradability in natural soil. This work provided a top-down approach for the preparation of biodegradable multilayer lms as packaging materials.

“…As illustrated in Fig. 3, the CNFs were used to produce films, which were subsequently evaluated as 2D scaffolds to culture mouse skeletal C2C12 myoblast cells [47]. Membranes having 3.1% residual proteins at their surface were found to promote higher cell density and spreading as well as a more orientated shape cell morphology compared to membranes constituted of bleached CNFs.…”

This review paper provides a recent overview of current international research that is being conducted into the functional properties of cellulose as a nanomaterial. A particular emphasis is placed on fundamental and applied research that is being undertaken to generate applications, which are now becoming a real prospect given the developments in the field over the last 20 years. A short introduction covers the context of the work, and definitions of the different forms of cellulose nanomaterials (CNMs) that are most widely studied. We also address the terminology used for CNMs, suggesting a standard way to classify these materials. The reviews are separated out into theme areas, namely healthcare, water purification, biocomposites, and energy. Each section contains a short review of the field within the theme and summarizes recent work being undertaken by the groups represented. Topics that are covered include cellulose nanocrystals for directed growth of tissues, bacterial cellulose in healthcare, nanocellulose for drug delivery, nanocellulose for water purification, nanocellulose for thermoplastic composites, nanocellulose for structurally colored materials, transparent wood biocomposites, supercapacitors and batteries.

“…This method, however, is not straightforward and can be particularly tedious. , Also, it usually involves the use of toxic chemical substances, which represent a problem from an environmental point of view. An alternative strategy that we recently proposed is to produce cellulose-based membranes with proteins covalently attached to their surfaces using cellulose fibrils that naturally possess covalently attached proteins to their surface . This has been achieved by controlled chemical isolation of cellulose fibrils from a tunicate (Pyura chilensis) since this cellulose source is naturally associated with relatively high amounts of proteins. − We referred this strategy to as a top-down approach …”

Protein functionalized cellulose fibrils were isolated from the tunic of Pyura chilensis and subsequently used to produce protein functionalized cellulose membranes. Bleached cellulose membranes were also obtained and used as reference material. FTIR and Raman spectroscopy demonstrated that the membranes are mostly constituted of cellulose along with the presence of residual proteins and pigments. Protein functionalized cellulose membranes were found to possess ∼3.1% of protein at their surface as measured by X-ray photoelectron spectroscopy. Powder X-ray diffraction, scanning electron microscopy, and thermogravimetric analysis were used to identify and semiquantify the amount of residual sand grains present within the structure of the membranes. The presence of residual proteins was found not to significantly affect the tensile mechanical properties of the membranes. Streaming ζ-potential was used to assess surface charges of the membranes. Below pH 4, nonbleached cellulose membranes possessed highly negative surfaces charges and also significantly less negative surface charges at physiological pH when compared to bleached cellulose membranes. No significant difference was found with respect to growth kinetics of myoblasts at the surface of the membranes for cell culturing times of 48 and 72 h. After 48 h of culture, protein functionalized cellulose-based membranes that possess ∼3.1% of proteins at their surface (H1) were, however, found to promote higher cell density, cell spreading, and more orientated shape cell morphology when compared to the other cellulose-based membranes (H3 and B) evaluated in the present study.
