“…Functional groups that contain oxygen are often found on the surface of the plasma-treated polymer because oxygen sticks very well to this surfaces. It is worth mentioning that the type of gas used to generate the plasma has a large effect, as was shown in experiments and stressed by Kumar et al [27].…”

Polymers are essential in several sectors, yet some applications necessitate surface modification. One practical and eco-friendly option is non-thermal plasma exposure. The present research endeavors to examine the impacts of dielectric barrier discharge atmospheric pressure plasma on the chemical composition and wettability properties of acrylonitrile butadiene styrene surfaces subject to the action of additive manufacturing. The plasma source was produced by igniting either helium or argon and then adjusted to maximize the operational conditions for exposing polymers. The drop in contact angle and the improvement in wettability after plasma exposure can be due to the increased oxygen-containing groups onto the surface, together with a reduction in carbon content. The research findings indicated that plasma treatment significantly improved the wettability of the polymer surface, with an increase of up to 60% for both working gases, while the polar index increased from 0.01 up to 0.99 after plasma treatment. XPS measurements showed an increase of up to 10% in oxygen groups at the surface of He–plasma-treated samples and up to 13% after Ar–plasma treatment. Significant modifications were observed in the structure that led to a reduction of its roughness by 50% and also caused a leveling effect after plasma treatment. A slight decrease in the glass and melting temperature after plasma treatment was pointed out by differential scanning calorimetry and broadband dielectric spectroscopy. Up to a 15% crystallinity index was determined after plasma treatment, and the 3D printing process was measured through X-ray diffraction. The empirical findings encourage the implementation of atmospheric pressure plasma-based techniques for the environmentally sustainable manipulation of polymers for applications necessitating higher levels of adhesion and specific prerequisites.

Cold plasma, an emerging and versatile non-thermal technology, has gained substantial attention, particularly in the domain of surface modification, specifically within the context of packaging films. Recent developments in cold plasma technology have unveiled its potential to improve various aspects of packaged films, including chemical composition, physical attributes, structural characteristics, and overall functionality. These enhancements encompass surface roughness, contact angles, flexibility, thermal stability, barrier properties, and antimicrobial efficacy. The imperative for the advancement and expansion of decay-control technologies is crucial, not only for preserving the quality of fresh fruits and vegetables but also for mitigating biological risks throughout postharvest, processing, and storage. This, in turn, extends the shelf life of these products. This review aims to comprehensively outline the various systems utilized in in-package cold plasma (CP) treatments and their interactions with key parameters that significantly influence the efficacy of the process on fruits and vegetables. In this order, the review furnishes a comprehensive understanding of the mechanisms through which cold plasma impacts the quality characteristics of diverse fruits and vegetables. The review paper examines the potential of cold plasma technology in inhibiting spoilage and pathogenic microorganisms, deactivating enzymes, and altering the physical, mechanical, and chemical characteristics of fresh fruits and vegetables during packaging. Furthermore, It deals with the effect of cold plasma technology on increasing the quality and characteristics of edible films, alongside its utilization as an antimicrobial agent in food packaging.
