“…In our study FE-SEM images with more magnification showed the presence of accumulation due to the lack of perfect solution. In line with the result obtained, Jo et al evaluated the morphology of the nanocomposite films and the dispersion of the AgNP by FE-SEM images and observed the white spots represent an agglomeration of AgNP as confirmed by the results of EDS [23]. As expected, the effects of Silver Nanocomposite on both gram positive and negative bacteria is quite obvious.…”

“…In order to confirm the efficiency of this method, Dehnavi et al applied this approach by using corona air plasma as a pretreatment of LDPE films to increase the adhesion of silver nanoparticle on the film surface. Jo et al asserted that the Ag/LDPE nanocomposite film has a comparable strength to that of commercial LDPE, although stiffness was increased at high Ag (240 mg/kg) concentration [23]. It is notable that using of diverse reducing agent can be produced different size of nanoparticle that having different antibacterial action.…”

Nanopackaging is one of the most significant subjects in food packaging And it is so important for food safety and food quality control, then we need natural method (without chemical material)for packaging process. In this study, the possibility of using nanocomposite (LDPE) based on silver nanoparticle as a food packaging was proposed. Chemical reduction method with Trisodium citrate as a reductant was applied for preparing silver nanoparticle. In the method mentioned using of diverse reducing agent can be produced different size of nanoparticles that having different antibacterial action. The nanostructure and particle size of of silvernanoparticles were confirmed by scanning electron microscopy(SEM). The average of particle size was 68 nm. After confirming the formation of nanoparticles, they were coated on the LDPE surface by melt mixing method. Surface morphology of the silver/LDPE nanocomposite was characterised by Transmission Electron Microscopy (TEM), Energy Dispersive X-ray (EDX) and X-ray Photoelectron Spectroscopy (XPS). The film thickness was 33.67nm. In addition, the antibacterial properties of the prepared nanocomposite film was evaluated by disc diffusion method. The results showed avourable antibacterial efficiency against Escheria Coli (ATCC 8739) and staphylococcus aureus(ATCC 6538) and The results show that the released silver from the coated film is enough to create antimicrobial activity in the incubated solution.

“…The antibacterial activity of the Mt, PL-Mt30, 1800W-OMt and PL-OMt powders was determined using the E2149 test of the American Society for the Testing and Materials (ASTM), according to previous studies with some modifications [25][26][27][28][29]. The Gram-negative bacteria E. coli and Gram-positive bacteria B. subtilis were used as the reference strains and a bacterial dispersion with a density of 10 8 CFU/mL was prepared in the experiments.…”

In this study, two types of antibacterial montmorillonites (Mt) were prepared using a facile method. The Mt modified with ε-polylysine hydrochloride (ε-PL) was named PL-Mt, while the Mt dually modified with dioctadecyl dimethylammonium chloride (D1821) and ε-PL was named PL-OMt. The results of the X-ray diffraction, Fourier-transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA) of the PL-Mt indicated that 30% ε-PL was the most suitable amount for intercalating the Mt. The particle size and distribution of the ε-PL in the solution demonstrated that the Mt d-value could not be further increased owing to the increasing ε-PL diameter. The result of the X-ray diffraction of PL-OMt displayed that ultrasonic treatment at 600 W facilitated ε-PL to intercalate into the OMt interlayer space. The PL-OMt prepared with ultrasonic treatment at 600 W exhibited antibacterial activity against Escherichia coli and Bacillus subtilis superior to that of the PL-OMt prepared with higher-power ultrasonic treatment. Thus, the addition of 30% ε-PL based on the dry Mt mass is the most suitable ratio for preparing PL-Mt, while ultrasonic treatment at 600 W is the most suitable for preparing PL-OMt. These findings may expand the application fields of ε-PL.

“…In that regard, various methods have been proposed to prevent bacterial activity [1]. Among them, the introduction of biocidal fillers directly into the polymeric matrix represents one of the most feasible way to do so [2][3][4]. In this way, it is possible to obtain the desired products without altering the production line and providing a simple way for the realization of the various biomedical probes.…”

Polyurethane-Based Composites: Effects of Antibacterial Fillers on the Physical-Mechanical Behavior of Thermoplastic Polyurethanes

et al. 2020

The challenge to manufacture medical devices with specific antibacterial functions, and the growing demand for systems able to limit bacterial resistance growth, necessitates the development of new technologies which can be easily produced at an industrial level. The object of this work was the study and the development of silver, titanium dioxide, and chitosan composites for the realization and/or implementation of biomedical devices. Thermoplastic elastomeric polyurethane was selected and used as matrix for the various antibacterial functions introduced during the processing phase (melt compounding). This strategy was employed to directly incorporate antimicrobial agents into the main constituent material of the devices themselves. With the exception of the composite filled with titanium dioxide, all of the other tested composites were shown to possess satisfactory mechanical properties. The best antibacterial effects were obtained with all the composites against Staphylococcus aureus: viability was efficiently inhibited by the prepared materials in four different bacterial culture concentrations.
