“…Polymeric nanocomposites with carbon nanomaterials have great potential for numerous uses. For instance, they are widely examined for food packaging due to their extraordinary antimicrobial effects against most types of microbes [ 103 ]. The exceptional mechanical properties of carbon nanomaterials make them very suitable for development of active/smart packaging materials, since their incorporation in films can lessen the proliferation of microorganisms by eliminating or dropping oxygen in the interior of the wrapping, thus expanding the product shelf life and simultaneously reducing weight.…”

The development of novel approaches to prevent bacterial infection is essential for enhancing everyday life. Carbon nanomaterials display exceptional optical, thermal, and mechanical properties combined with antibacterial ones, which make them suitable for diverse fields, including biomedical and food applications. Nonetheless, their practical applications as antimicrobial agents have not been fully explored yet, owing to their relatively poor dispersibility, expensiveness, and scalability changes. To solve these issues, they can be integrated within polymeric matrices, which also exhibit antimicrobial activity in some cases. This review describes the state of the art in the antibacterial applications of polymeric nanocomposites reinforced with 0D fullerenes, 1D carbon nanotubes (CNTs), and 2D graphene (G) and its derivatives such as graphene oxide (GO) and reduced graphene oxide (rGO). Given that a large number of such nanocomposites are available, only the most illustrative examples are described, and their mechanisms of antimicrobial activity are discussed. Finally, some applications of these antimicrobial polymeric nanocomposites are reviewed.

“…Inadequate barrier properties are critical issues in polymer materials, thus, by incorporating substances with specific properties, better resistance to water vapor and gasses permeability can be achieved. Novel polymer materials based on nanotechnology can provide solutions to increase the polymers performances [ 1 , 2 , 3 , 4 , 5 ]. In many applications of combination of properties, the most effective is use of laminated structures, e.g., bilayer materials where the active particles can be incorporated without degradation of the polymer structure of the carrier film.…”

Development of PE/PCL Bilayer Films Modified with Casein and Aluminum Oxide

et al. 2021

The studied samples were prepared from polyethylene (PE) polymer which was coated with modified polycaprolactone (PCL) film in order to obtain bilayer films. Thin PCL film was modified with casein/aluminum oxide compound to enhance vapor permeability as well as mechanical and thermal properties of PE/PCL films. Casein/aluminum oxide modifiers were used in order to achieve some functional properties of polymer film that can be used in various applications, e.g., reduction of water vapor permeability (WVTR) and good mechanical and thermal properties. Significant improvement was observed in mechanical properties, especially in tensile strength as well as in water vapor values. Samples prepared with aluminum oxide particles indicated significantly lower values up to 60%, and samples that were prepared with casein and 5% Al2O3 showed the lowest WVTR value.

“…The problems of modifying films such as polyethylene in order to change their properties have been discussed in many studies [6,27]. New properties were obtained by introducing various types of additives into the film material, such as slips or fillers (including nanofillers) [15,22,28], as well as by physical modification of the film surface, e.g. via activating film surface by various methods [6,20,23] or changing its geometric structure, e.g.…”

This paper discusses the problems connected with applying a biocidal substance onto the surface of a blown extruded polyethylene film in order to improve the functional properties of the film while maintaining its processing properties unchanged. The objective of the study was to determine the relationship between biocide application method and selected properties of the tube film. Two methods of biocide application onto the film surface were developed: one relied on spraying the biocide onto the hot melt surface directly during the extrusion process, while in the other the biocide was sprayed horizontally onto the blown film after the extrusion process. Biocide distribution uniformity, friction coefficients and surface free energy of the modified film were examined, and the quality and mechanical strength of heat-sealed joints were estimated. In addition, the geometric properties of the blown film were determined.
