“…CA purified and TFCAN-electrospinning have a degradation temperature of 358°C and 353°C, respectively, due to decomposition of the polymer chains to dehydrated and volatile compounds. 40 In the case of TFCAN-acid hydrolysis, two degradation temperatures were observed at 277°C and 444°C. The first degradation temperature like the purified CA and TFCAN-electrospinning is due to decomposition of the CA chains and the second degradation temperature is related to the acid hydrolysis time with H 2 SO 4 .…”

Cigarette waste pollutes the environment and is a desired problem to be addressed by humans. However, such waste can be recycled by converting it into raw material for the manufacture of new products. In this study, cigarette butt waste was collected and used for fabricating thin films of cellulose acetate nanofibers (TFCAN) through electrospinning or acid hydrolysis processes. Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) were employed to characterize the structural and thermal properties of TFCAN. FTIR and TGA results for the TFCAN obtained from acid hydrolysis process showed similar behavior for cellulose nanocrystals. The images from scanning electron and atomic force microscope confirmed the obtaining of TFCAN.

New polyoxometalate (POM)/polymer hybrid composites were prepared by photopolymerization under mild conditions for suitable photocatalytic processes. Polyoxometalates were incorporated in special photosensitive resins, which were photopolymerized under visible light to obtain new materials with photocatalytic activity for dye removal. The synthesized composites were characterized by real-time FT-IR, and the photocatalytic ability was investigated on Eosin-Y removal using photolysis under near UV irradiation. Interestingly, the polyoxometalates keep their photocatalytic properties, while incorporated into the polymeric matrix since very high conversion rates of Eosin-Y were achieved. Indeed, degradation efficiencies of about 98% and 93% were registered when using H 3 PMo 12 O 40 / polymer and 94% for SiMo 12 O 40 (IPh 2 ) 4 /polymer composites, respectively. These first results reported in this article show that the new synthesized POM/polymer composites could be considered as promising materials for green and more suitable organic dye removal from aqueous solutions.

“…Many cellulose derivatives have arisen in order to overcome the limited solubility of cellulose in general organic solvents [28]. CA is one of the most important cellulose derivatives, with applications in textile, plastics, cigarette filters, diapers, sensors, LCD screens, catalysts, coatings, semi-permeable membranes for separation processes, nano and macro composites, and fibers and films for biomedical devices [97,98]. This polymer is under great consideration in the biomedical industry due to its biodegradability, biocompatibility, mechanical performance, non-toxicity, high affinity, good hydrolytic stability, relative low cost, and excellent chemical resistance [99].…”

Electrospun Nanocomposites Containing Cellulose and Its Derivatives Modified with Specialized Biomolecules for an Enhanced Wound Healing

Wound healing requires careful, directed, and effective therapies to prevent infections and accelerate tissue regeneration. In light of these demands, active biomolecules with antibacterial properties and/or healing capacities have been functionalized onto nanostructured polymeric dressings and their synergistic effect examined. In this work, various antibiotics, nanoparticles, and natural extract-derived products that were used in association with electrospun nanocomposites containing cellulose, cellulose acetate and different types of nanocellulose (cellulose nanocrystals, cellulose nanofibrils, and bacterial cellulose) have been reviewed. Renewable, natural-origin compounds are gaining more relevance each day as potential alternatives to synthetic materials, since the former undesirable footprints in biomedicine, the environment, and the ecosystems are reaching concerning levels. Therefore, cellulose and its derivatives have been the object of numerous biomedical studies, in which their biocompatibility, biodegradability, and, most importantly, sustainability and abundance, have been determinant. A complete overview of the recently produced cellulose-containing nanofibrous meshes for wound healing applications was provided. Moreover, the current challenges that are faced by cellulose acetate- and nanocellulose-containing wound dressing formulations, processed by electrospinning, were also enumerated.
