“…nanoparticles with the help of DC magnetron sputter coating and then zinc oxide nanoparticles using RF reactive sputter coating technique. Figure 6a-f describes the carbon, oxygen, copper and zinc element mapping over the surface of bacterial cellulose, while Figure 6g describes the peaks of elements and shows the presence of elements with a unique pattern [15,61]. The most important thing that is observed in both Figure 5g and 6g is a peak of oxygen in the EDS spectra, which confirms that copper and zinc are found in their oxidized forms in both nanocomposites.…”

“…Copper nanoparticles have good antibacterial and thermal characteristics; in addition, their metallic ions can restrict the activities of proteins clusters and improve the surface of the film. Additionally, because of their biodegradability and high stability, they are suitable to be used with cellulosic materials [15]. In industrial applications, a requirement of many cost-effective instruments is to control microwaves, thereby absorbing harmful radiation.…”

In our study, the surface of bacterial cellulose was successively modified by copper and zinc oxide nanoparticles using direct current (DC) magnetron sputtering and radio frequency (RF) reactive sputter coating techniques. The target materials, copper and zinc, were 99.99% pure and used in the presence of argon (Ar) gas, while zinc nanoparticles were sputtered in the presence of oxygen gas to make zinc oxide nanoparticles. The as-prepared bacterial cellulose/copper/zinc oxide nanocomposite has good ultraviolet resistance, anti-static and antibacterial characteristics. The surface morphology and chemical composition of the nanocomposite were examined by X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopic (EDS) techniques. The prepared bacterial cellulose/copper/zinc oxide nanocomposite illustrates excellent ultraviolet resistance (T.UVA%; 0.16 ± 0.02, T.UVB%; 0.07 ± 0.01, ultraviolet protection factor (UPF); 1850.33 ± 2.12), antistatic behavior (S.H.P; 51.50 ± 4.10, I.E. V; 349.33 ± 6.02) and antibacterial behavior (Escherichia coli; 98.45%, Staphylococcus aureus; 98.11%). Our nanocomposite prepared by sputter coating method could be a promising and effective candidate for ultraviolet resistance, antistatic and antibacterial in term of functional, technical, medical and in many daily life applications.Coatings 2020, 10, 364 2 of 17 extensive attention toward its use as a conductive material due to its low resistance characteristic in such applications. Cellulosic materials such as bacterial cellulose (BC) do not show any type of bactericidal property [16]. In order to acquire the bactericidal characteristic from bacterial cellulose, many scientists have worked on bacterial cellulose, that work encompassing several types of metals and metal oxide nanoparticles, among which Cu, CuO and ZnO conclusively exist [17,18]. Additionally, Zinc oxide has distinguished properties and has been considered for serval applications in terms of piezoelectric gadgets, semiconductors and sensors, and for antimicrobial functions [19,20]. Nowadays, researchers have more interest in using zinc oxide in the composition of nanoparticles with different approaches to regulate its structure and scope. Preparation of a nanocomposite with suitable base materials and zinc oxide nanoparticles could advance multifunctional materials, which exhibit a wide range of UV-resistance and antibacterial applications [21,22].Human beings, as well as other living organisms, are affected by ultraviolet radiation in this universe. A decrease in environmental pollution has gained more attention, but there still needs to be a type of composite which can resist ultraviolet radiation to save the lives of all creatures [23,24]. The main cause of skin cancer is ultraviolet radiation, which is a medium of free radicals. Moreover, it is a cause of environmental degradation; and damages various pigments and materials and degrades their physical characteristics [25]. The deposition of zinc oxide nanoparticles on sub...

Background. Food nanopackaging helps maintain food quality against physical, chemical, and storage instability factors. Copper oxide nanoparticles (CuONPs) can improve biopolymers’ mechanical features and barrier properties. This will lead to antimicrobial and antioxidant activities in food packaging to extend the shelf life. Scope and Approach. Edible coatings based on carbohydrate biopolymers have improved the quality of packaging. Several studies have addressed the role of carbohydrate biopolymers and incorporated nanoparticles to enhance food packets’ quality as active nanopackaging. Combined with nanoparticles, these biopolymers create film coatings with an excellent barrier property against transmissions of gases such as O2 and CO2. Key Findings and Conclusions. This review describes the CuO-biopolymer composites, including chitosan, agar, cellulose, carboxymethylcellulose, cellulose nanowhiskers, carrageenan, alginate, starch, and polylactic acid, as food packaging films. Here, we reviewed different fabrication techniques of CuO biocomposites and the impact of CuONPs on the physical, mechanical, barrier, thermal stability, antioxidant, and antimicrobial properties of carbohydrate-based films.

“…[ 13 ] The latter method is superior in terms of sustained release and prolonged effect. Current antibacterial PVC materials are usually loaded with biocidal nanoparticles (NP) such as chitosan, [ 14 ] copper, [ 15 ] silver, [ 16 ] SiO 2 , [ 17 ] and ZnO. [ 18 ] Although these PVC composites can achieve an excellent reduction of viable bacterial cells in comparison to the untreated PVC, they suffer from high costs, sacrificing the polymer mechanical properties and serious toxicity.…”

Global bacterial infections associated with conventional polyvinyl chloride (PVC) medical devices place a heavy burden on healthcare systems and thus it will be desirable if medical devices are made from antimicrobial PVC. There are numerous studies focusing on polymer surface modifications to either leach antimicrobial agents or kill pathogenic microbes upon direct contact. In this work, mannitol fumarate ester‐based aluminum metal alkoxide (MFE‐Al) additive was developed to confer simultaneously improved antibacterial property and enhanced high temperature sterilization resistance of the resultant PVC. Data obtained confirm that the MFE‐Al stabilized PVC sheets significantly inhibit 98% bacterial growth. They also show biocompatibility with cultured H9C2 cardiomyocytes and hemocompatibility in vitro. Dry heat sterilization is generally not suitable for PVC medical wares due to their poor thermal compatibility. Surprisingly, our antimicrobial‐biocompatible PVC can maintain stability at 180°C for 90 min. Such a high thermal stability indicates the MFE‐Al stabilized PVC can endure 90 cycles of dry‐heat sterilization without significant damage. This study may provide a solution to reduce PVC medical waste for a maximum benefit without compromising human health or the environment.
