Investigation of biodegradability of composites based on polyethylene and polysaccharides by independent methods

Effect of chitosan addition on the properties of low-density polyethylene blend as potential bioplastic

“…The degradation step of the synthetic-natural blend is initiated by destruction of the natural compounds. Then, it leads to the appearance of crack propagation followed by the formation of free radicals on the surface of materials ( Rogovina et al., 2018 ). Therefore in this case, the degradation step is initiated by the destruction of chitosan.…”

Polysaccharides for Biodegradable Packaging Materials: Past, Present, and Future (Brief Review)

“…Obviously, the first approach given above is the most studied for cellulose-based materials. Therefore, a lot of research groups have been interested in the creation of biodegradable systems of cellulose with large-tonnage synthetic polyolefins, namely, polyethylene for example [ 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. In [ 27 , 28 , 29 , 30 , 31 ], a collective of authors developed biodegradable compositions based on cellulose/ethylcellulose and low-density polyethylene.…”

“…Investigation of mechanical, thermal properties, and biodegradability showed that varying the content of polysaccharide one can obtain the materials with optimal properties. Therefore, in order to improve these characteristics, another polysaccharide (chitin/chitosan) or poly(ethylene oxide) was introduced [ 32 , 33 , 34 , 35 ]. It was demonstrated that with preservation of good mechanical properties, the biodegradability was improved (intensified) compared to binary cellulose-polyethylene blends.…”

“…The biodegradable compositions of cellulose and derivatives with other polysaccharides are described in numerous works, for example, [ 34 , 35 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 ]. All the mentioned works describe in detail the properties and possible application areas for cellulose-based compositions.…”

“…One of the largest research fields is the development of biodegradable materials based on starch with other polysaccharide(s). In order to obtain antimicrobial packaging materials, starch was mixed with chitin/chitosan [ 34 , 35 , 113 , 114 , 115 , 116 , 117 , 118 , 119 , 120 , 121 , 122 , 123 ]. The solution casting method was used to produce edible corn starch-chitosan film possessing antimicrobial properties [ 118 ], which can prevent food spoilage.…”
