Cellulose triacetate is a polymer film derived from cellulose treated with an acetylating agent, which renders the cellulose polymers more soluble in organic solvents. Cellulose triacetate can be used to manufacture high-performance membranes characterized by well-defined pores for dialysis and reverse osmosis and is often combined with plasticizer and an ionophore for ion sensing and separation. It is also implemented in the production of photographic film and polarized film for liquid crystal displays.

Cellulose triacetate (CTA) Hollow-Fiber (HF) Membranes for Sustainable Seawater Desalination: A Review
Membranes (Basel) 2021 Mar 8;11(3):183.PMID:33800203DOI:10.3390/membranes11030183.
Cellulose triacetate (CTA)-based hollow fiber (HF) membrane is one of the commercially successful semipermeable membranes that has had a long progress since the time the excellent semi-permeable feature of cellulose-based polymers was found in 1957. Because of the reliable and excellent performances, especially for drinking water production from seawater, CTA-HFs have been widely used as reverse osmosis (RO) membranes, especially in arid regions. In this review, recent developments and research trends on CTA-HF membranes for seawater reverse osmosis (SWRO) plants were presented. A flux analytical model, an optimization strategy for chlorine injection without losing salt rejection performance, and a module of current high performance CTA RO membranes along with its plant operation data were updated in this paper. Furthermore, a newly developed CTA-HF membrane for brine concentration (BC) application (called BC membrane) was also addressed. Finally, RO/BC hybrid operation was introduced as an effective SWRO desalination technique that enables minimizing the volume of brine disposal from the RO plant by increasing the recovery ratio and the subsequent amount of produced freshwater, without an additional energy input.
Cellulose triacetate as a high-performance membrane
Contrib Nephrol 2011;173:156-163.PMID:21865788DOI:10.1159/000329055.
The Cellulose triacetate membrane is one of the typical high-performance membranes. Cellulose triacetate is a plastic material manufactured from cellulose. The hydroxyl group of cellulose is chemically substituted for the carboxyl group. Therefore, its characteristics are quite different from cellulose. The Cellulose triacetate membrane has a homogeneous membrane structure. It can be produced with a wide range of permeability, from low-flux performance to super high-flux performance. Because the thickness of the membrane is thin, and flow distribution of the dialysate (due to the moiré structure) is uniform, this enables the development of a dialyzer with high diffusive efficiency. Recently, this new product, improved through a sieving process, produced a uniform pore size distribution. As for the dialyzer, through sterilization by γ-rays with the absence of oxygen, now enables long-term safety of the product. Several clinical improvements have been reported, such as high antithrombus, the improvement of lipid metabolism and the reduction of biomarkers. Thus, continuous membrane development is desired, made of safe and stable Cellulose triacetate material.
Toughening Cellulose: Compatibilizing Polybutadiene and Cellulose triacetate Blends
ACS Macro Lett 2019 Apr 16;8(4):447-453.PMID:35651130DOI:10.1021/acsmacrolett.9b00136.
We report the synthesis of an ABA triblock copolymer of the structure CTA-b-PB-b-CTA (CTA = Cellulose triacetate and PB = polybutadiene) and its ability to compatibilize immiscible CTA/PB polymer blends. CTA-b-PB-b-CTA was synthesized via ring-opening metathesis polymerization of cyclooctadiene (COD) in the presence of CTA containing a single olefin on the reducing end. The ABA triblock copolymer was incorporated into CTA/PB blends, resulting in films that were clear, tough, and creaseable, and increases in modulus, elongation at break, and toughness were observed with addition of as little as 1 wt % compatibilizer. Scanning electron microscopy revealed well-defined PB phases in the CTA matrix that decreased in domain size as more compatibilizer was added. This work may enhance the application scope of CTA and other cellulose-derived renewable polymers.
Cellulose Triacetate-Based Mixed-Matrix Membranes with MXene 2D Filler-CO2/CH4 Separation Performance and Comparison with TiO2-Based 1D and 0D Fillers
Membranes (Basel) 2022 Sep 22;12(10):917.PMID:36295678DOI:10.3390/membranes12100917.
Mixed-matrix membranes (MMMs) possess the unique properties and inherent characteristics of their component polymer and inorganic fillers, or other possible types of additives. However, the successful fabrication of compact and defect-free MMMs with a homogeneous filler distribution poses a major challenge, due to poor filler/polymer compatibility. In this study, we use two-dimensional multi-layered Ti3C2Tx MXene nanofillers to improve the compatibility and CO2/CH4 separation performance of Cellulose triacetate (CTA)-based MMMs. CTA-based MMMs with TiO2-based 1D (nanotubes) and 0D (nanofillers) additives were also fabricated and tested for comparison. The high thermal stability, compact homogeneous structure, and stable long-term CO2/CH4 separation performance of the CTA-2D samples suggest the potential application of the membrane in bio/natural gas separation. The best results were obtained for the CTA-2D sample with a loading of 3 wt.%, which exhibited a 5-fold increase in CO2 permeability and 2-fold increase in CO2/CH4 selectivity, compared with the pristine CTA membrane, approaching the state-of-the-art Robeson 2008 upper bound. The dimensional (shape) effect on separation performance was determined as 2D > 1D > 0D. The use of lamellar stacked MXene with abundant surface-terminating groups not only prevents the aggregation of particles but also enhances the CO2 adsorption properties and provides additional transport channels, resulting in improved CO2 permeability and CO2/CH4 selectivity.
Synthesis and Characterization of Cellulose triacetate Obtained from Date Palm ( Phoenix dactylifera L.) Trunk Mesh-Derived Cellulose
Molecules 2022 Feb 21;27(4):1434.PMID:35209224DOI:10.3390/molecules27041434.
Cellulosic polysaccharides have increasingly been recognized as a viable substitute for the depleting petro-based feedstock due to numerous modification options for obtaining a plethora of bio-based materials. In this study, Cellulose triacetate was synthesized from pure cellulose obtained from the waste lignocellulosic part of date palm (Phoenix dactylifera L.). To achieve a degree of substitution (DS) of the hydroxyl group of 2.9, a heterogeneous acetylation reaction was carried out with acetic anhydride as an acetyl donor. The obtained cellulose ester was compared with a commercially available derivative and characterized using various analytical methods. This Cellulose triacetate contains approximately 43.9% acetyl and has a molecular weight of 205,102 g·mol-1. The maximum thermal decomposition temperature of acetate was found to be 380 °C, similar to that of a reference sample. Thus, the synthesized ester derivate can be suitable for fabricating biodegradable and "all cellulose" biocomposite systems.
