“…The ring-opening reactions of polycyclic carbonates with diamines for the production of PUs have also been reported as green method [39][40][41]. This reaction involved a cyclic carbonate with aliphatic amines with β-hydroxyls as side-chain and resultant PUs exhibited hydrophilic nature [42]. TPU was synthesized by using IPPC dissolved in NMP, and adding to poly propylene ether diamine through NIR [43] Scheme 5.…”

Polyurethanes as one of the leading elastomers are explored in academics as well as in industry. These are segmented macromolecules having alternate sequence of soft and hard segments. Structure-property correlation between these segments has been extensively reported in the literature. PUs are used widely in coatings, varnishes, glues, foams, adhesives, sealants, automobile parts, synthetic leather etc. Its application in biomedical devices is also growing rapidly. It is therefore need to highlights the recent developments in this fast growing field. The present article is summarized the conventional and ecofriendly synthetic routes for the preparation of PUs. Conventionally, PUs was synthesized by isocyanates route, later shortcoming of this method explore new synthesis method in which either used biobased polyol or non isocyanates route for preparation of ecofriendly PUs. The applications of different types of PUs coating in various fields are also highlighted in this review.

“…Several studies focused on chemical and physical modifications as a way to minimize these known shortcomings of chitosan [2,[13][14][15]. Recently, Schio et al [16] developed a polyurethane/chitosan composite foam based on ricinoleic acid that was able to overcome the disadvantages related to chitosan, presenting good adsorbent potential. However, the studies were carried out only in discontinuous systems.…”

The potential of a chitosan/polyurethane foam (CTS/PU) fixed‐bed column for the removal of Allura Red dye (AR) from aqueous solutions was evaluated. Breakthrough curves were constructed under different conditions and optimized using response surface methodology (RSM). The empirical models Thomas, Yoon‐Nelson, and Bed Depth Service Time (BDST) were fitted to the experimental data. The dynamic models of Yoon‐Nelson and BDST accurately fitted the experimental data. As a result, CTS/PU can be successfully applied in a fixed‐bed adsorption operation to remove AR dye.

“…Meanwhile, when starch is treated with kaolin at high temperature, a starch with improved biodegradability properties is obtained [ 2 ]. Some of their applications are encapsulating agent [ 7 , 8 , 9 ], bio-adsorbent [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ], foams [ 19 , 20 , 21 , 22 , 23 , 24 ], food packaging [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ], and medical applications [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ] ( Figure 3 ).…”

Two Fascinating Polysaccharides: Chitosan and Starch. Some Prominent Characterizations for Applying as Eco-Friendly Food Packaging and Pollutant Remover in Aqueous Medium. Progress in Recent Years: A Review

2021

The call to use biodegradable, eco-friendly materials is urgent. The use of biopolymers as a replacement for the classic petroleum-based materials is increasing. Chitosan and starch have been widely studied with this purpose: to be part of this replacement. The importance of proper physical characterization of these biopolymers is essential for the intended application. This review focuses on characterizations of chitosan and starch, approximately from 2017 to date, in one of their most-used applications: food packaging for chitosan and as an adsorbent agent of pollutants in aqueous medium for starch.
