“…Natural polymers such as chitosan, alginate, cellulose, and starch have been widely used for the preparation of nanoparticles due to their biocompatibility, biodegradability, and low toxicity. However, natural polymer-based nanoparticles often have limitations in terms of their stability, drug loading capacity, and targeted delivery, which can affect their efficacy as drug delivery vehicles [ 58 ].…”

Natural polymers have attracted significant attention in drug delivery applications due to their biocompatibility, biodegradability, and versatility. However, their surface properties often limit their use as drug delivery vehicles, as they may exhibit poor wettability, weak adhesion, and inadequate drug loading and release. Plasma treatment is a promising surface modification technique that can overcome these limitations by introducing various functional groups onto the natural polymer surface, thus enhancing its physicochemical and biological properties. This review provides a critical overview of recent advances in the plasma modification of natural polymer-based drug delivery systems, with a focus on controllable plasma treatment techniques. The review covers the fundamental principles of plasma generation, process control, and characterization of plasma-treated natural polymer surfaces. It discusses the various applications of plasma-modified natural polymer-based drug delivery systems, including improved biocompatibility, controlled drug release, and targeted drug delivery. The challenges and emerging trends in the field of plasma modification of natural polymer-based drug delivery systems are also highlighted. The review concludes with a discussion of the potential of controllable plasma treatment as a versatile and effective tool for the surface functionalization of natural polymer-based drug delivery systems.

Sulfur hexafluoride (SF6) gas is a stable gas that is widely used in gas insulated lines (GILs) in power systems. However, in GIL, SF6 gas is in the environment of high temperature, high pressure and high voltage for a long time, SF6 gas will decompose into toxic gas, damage electrical equipment, and pose a huge threat to human body and ecological environment. In addition, SF6 gas is a greenhouse gas that is strictly forbidden to leak. Once leaked, it will cause great harm to the environment. Therefore, it is necessary to recover and purify the SF6 gas in the power system GIL. In this paper, a molecular model of carbon nanotubes is constructed, and the density functional theory is used to analyze the changes of charge distribution, density of states and molecular orbitals after adsorption of SF6 decomposition products by carbon nanotubes, and determine the gas-sensing response of carbon nanotubes to gas molecules characteristic.

“…Currently, polyester fiber is the most widely used method because it shows many advantages, such as good mechanical properties, moisture resistance, resistance to temperature and light, and good chemical resistance to solutions of acids and bases at room temperature [ 5 ]. However, it has high crystallinity, low surface energy, and poor wettability [ 6 ], which make it difficult to create functionalities by anchorage with conventionally available chemicals [ 7 ]. The modification of the surface layers (SLs) of polymers is one of the ways to achieve the desired surface properties [ 8 ].…”

Surface treatments for textile substrates have received significant attention from researchers around the world. Ozone and plasma treatments trigger a series of surface alterations in textile substrates that can improve the anchoring of other molecules or particles on these substrates. This work aims to evaluate the effect of ozone and plasma treatments on the impregnation of polymeric microcapsules containing lavender oil in polyester fabrics (PES). Microcapsules with walls of chitosan and gum arabic were prepared by complex coacervation and impregnated in PES, plasma-treated PES, and ozone-treated PES by padding. The microcapsules were characterized for their size and morphology and the surface-treated PES was evaluated by FTIR, TGA, SEM, and lavender release. The microcapsules were spherical in shape, with smooth surfaces. The FTIR analyses of the textile substrates with microcapsules showed bands referring to the polymers of the microcapsules, but not to the lavender; this was most likely because the smooth surface of the outer wall did not retain the lavender. The mass loss and the degradation temperatures measured by TGA were similar for all the ozone-treated and plasma-treated polyester samples. In the SEM images, spherical microcapsules and the impregnation of the microcapsules of larger sizes were perceived. Through the lavender release, it was observed that the plasma and ozone treatments interfered both with the amount of lavender delivered and with the control of the delivery.
