Biodegradable film from mango kernel starch: Effect of plasticizers on physical, barrier, and mechanical properties

Plastic film mulching is widely practiced in arid and semiarid farming systems, but the accumulation of plastic residues in soils can negatively affect soil properties. Therefore, efficient means of plastic film degradation are urgently needed to mitigate its unfriendly environmental impacts for sustainable land use. Here, we characterized the effects of tensile stress (TS) and soil burial (SB) on potential degradation properties of three film types: Polyethylene film (PEF), oxo-biodegradable film (OBDF), and biodegradable film (BDF). Weight loss, mechanical properties, hydrophilicity, functional groups, and crystallinity were recorded after TS and SB treatments. The results indicated that: (1) Weight loss of plastic films was associated with SB, although the extent of weight loss depended on film type and was highest in BDF, (2) application of TS before SB weakened the mechanical properties of the films and increased their hydrophilicity, creating favorable conditions for the settlement of microorganisms on the film surface, (3) PEF treated with TS and SB had higher functional group indices and lower crystallinity. Our results highlighted that the combination of TS and SB has the potential to accelerate plastic film degradation.

Chia oil production and consumption have increased in recent years, producing a large number of by-products that had low utility or economic value for the industry. In this study, a biodegradable film was successfully prepared from mucilage extracted from defatted chia flour. The physical-chemical, optical, water vapor permeability (WVP), and mechanical properties of films made with two different types of chia matrixes (defatted flour and whole seeds) were determined. In general, defatted chia flour films exhibited a slightly reddish and yellowish color but still transparent in appearance, were good visible light barriers, and had better mechanical properties than films made with whole seeds. They also have greater WVP values than synthetic films such as low-density polyethylene. The results of the present study demonstrated that defatted chia flour can be used in producing edible films with improved quality characteristics.

Resource of reactor with PWR is defined, in the first instance, by foundation of integrity of the third physical barrier of safety. The third physical barrier of safety provides a reliable keeping of the coolant in the boundaries of NPP primary circuit. More than thirty year history shows, that reactor vessel is a weak spot in this barrier, the metal of the pressure vessel is subjected to intensive irradiation. The mechanism of operational damage of pressure vessel steel is represented in Fig. 1. This article describes the works, which were conducted by VNIIAES during the last years in the field of elaboration of specimen-free methods and means of inspection (control) of physical-mechanical properties of pressure vessels welds metal of NPPs with PWR. On the base of analysis of that factors, which exercise the most substantial influence on the irradiation embrittlement of pressure vessel materials and on the base of distribution of these factors by degree of significance, there were selected the most appropriate specimen-free methods of inspection: kinetic indentation and kinetic magnetising. It was presented the description of the specimen-free methods, devices and of the results of laboratory measurements, and also the description of the manufacturing procedure and the procedure of certification of the methods on full-scale slabs from WWER-1000 pressure vessel. In the article also is described the example of using of the specimen-free methodics by full-scale inspection (control) of the metal of reactor internal components and of pressure vessel of WWER-1000 of Rostov NPP Unit 1.

ε-polylysine (ε-PL) was blended with polyvinyl alcohol (PVA) to obtain biodegradable films. Blends and neat polymer films (PVA) were characterized for their structural and mechanical properties as well as antibacterial activity. The addition of ε-polylysine reduced Young modulus (Eyoung), tensile strength (TS) and elongation at break (%E) of the ε-polylysine/PVA film. The ε-polylysine/PVA film shows good antibacterial activity and therefore has potential applications in packaging industry.

Biodegradable film blends of soya bean flour with poly (vinyl alcohol) (PVA) were prepared by solution mixing and solution casting. The main goal of this study is to investigate the effect of soya bean flour content in the PVA film. Mechanical properties of the obtained blends were assessed by tensile testing, whereas the biodegradability were assessed by subjected the films in natural weathering. The incorporation of soya bean flour decreased the tensile strength and elongation at break of PVA film. However, the tensile modulus increased with the addition of soya bean flour. The reduction in tensile properties of the PVA/soya bean flour blend films revealed that the presence of soya bean flour show positive effect in degradation.
