“…Sifuentes‐Nieves et al 26 studied CAR of films with high‐amylose corn starch subjected to cold plasma treatment with hexamethyldisiloxane (HMDSO), in which there was an increase of 4 to 13% in CAR compared with the untreated films. This behaviour was explained due to a faster rearrangement of the helical order of amylose chains than the rearrangement of the amylopectin chains during the drying process, especially with the high content of amylopectin present in this studio.…”

In recent years, films of biodegradable materials have been studied to determine and improve their physical properties, mechanical strength, and hydrophobicity. This research focused on the study of banana starch-based films (Musa sapientum). The films were prepared using the casting method, and a 2k experimental design was conducted to evaluate the effects of cold plasma treatment on three steps of film production. Dielectric barrier discharge (DBD) plasma (excitation frequency of 400 Hz, voltage of 20 kV, and 15 min of processing time) was applied in three processing phases: on the starch granules, the filmogenic suspension, and the film. Plasmatreated films presented better short-range order structure degree (or crystalline/ amorphous ratio) than untreated films. Significant differences were observed on the surface of the films, especially when the filmogenic suspension or the film were subjected to plasma treatment. Films produced with the treated starch granules and filmogenic suspension presented the lowest values of moisture (<9.5%) and solubility (<31.1%), while the films produced with DBD plasma-treated starch granules and also subjected to plasma treatment presented the highest water contact angle (65.1 ), the highest tensile strength (9.11 MPa), and good puncture resistance (0.33 MPa), resulting in the highest hydrophobicity and highest mechanical strength among the tested films. Research must be done to adapt these promising results and apply to other techniques and botanical sources.

“…Among them, for example, ozonation forces the loss of starch granulation, and treatment with high hydrostatic pressure affects its crystallinity and gelatinization [ 41 , 42 ]. Nonthermal methods can also induce certain chemical changes, e.g., in the case of plasma, which is able to induce crosslinking in starch molecules, thus introducing changes in the thermal properties of starch—melting temperatures and other phase transitions [ 43 , 44 ].…”

It has long been known that starch as a raw material is of strategic importance for meeting primarily the nutritional needs of people around the world. Year by year, the demand not only for traditional but also for functional food based on starch and its derivatives is growing. Problems with the availability of petrochemical raw materials, as well as environmental problems with the recycling of post-production waste, make non-food industries also increasingly interested in this biopolymer. Its supporters will point out countless advantages such as wide availability, renewability, and biodegradability. Opponents, in turn, will argue that they will not balance the problems with its processing and storage and poor functional properties. Hence, the race to find new methods to improve starch properties towards multifunctionality is still ongoing. For these reasons, in the presented review, referring to the structure and physicochemical properties of starch, attempts were made to highlight not only the current limitations in its processing but also new possibilities. Attention was paid to progress in the non-selective and selective functionalization of starch to obtain materials with the greatest application potential in the food (resistant starch, dextrins, and maltodextrins) and/or in the non-food industries (hydrophobic and oxidized starch).

“…Later Anastácia et al [ 306 ] analyzed the corn starch film modified using SF 6 plasma with a capacitively coupled plasma-enhanced chemical vapor deposition (CVD) reactor. Instead of SF 6 plasma, Sifuentes-Nieves et al [ 307 ] used hexamethyldisiloxane (HDMSO) plasma and achieved improved barrier performance against water. Later, they analyzed the effectiveness of HDMSO plasma on three different granular corn starches (normal, Hylon V, and Hylon VII) [ 308 ].…”

Recently, natural as well as synthetic polymers have been receiving significant attention as candidates to replace non-renewable materials. With the exponential developments in the world each day, the collateral damage to the environment is incessant. Increased demands for reducing pollution and energy consumption are the driving force behind the research related to surface-modified natural fibers (NFs), polymers, and various derivatives of them such as natural-fiber-reinforced polymer composites. Natural fibers have received special attention for industrial applications due to their favorable characteristics, such as low cost, abundance, light weight, and biodegradable nature. Even though NFs offer many potential applications, they still face some challenges in terms of durability, strength, and processing. Many of these have been addressed by various surface modification methodologies and compositing with polymers. Among different surface treatment strategies, low-temperature plasma (LTP) surface treatment has recently received special attention for tailoring surface properties of different materials, including NFs and synthetic polymers, without affecting any of the bulk properties of these materials. Hence, it is very important to get an overview of the latest developments in this field. The present article attempts to give an overview of different materials such as NFs, synthetic polymers, and composites. Special attention was placed on the low-temperature plasma-based surface engineering of these materials for diverse applications, which include but are not limited to environmental remediation, packaging, biomedical devices, and sensor development.
