Polymeric materials are used for vibration protection owing to their high-energy dissipation or adsorption. In this study, polyurethane elastomers (PUEs) were prepared using six kinds of chain extender and three types of cross-linking agent. The relationships between their structures and vibration isolation performances were investigated in detail using an independent building vibration isolation sensor. The results showed that elastomers with fewer main chain carbon atoms exhibited better vibration isolation performance. With increasing number of side groups of the chain extender, both the damping and vibration isolation properties were improved. For different cross-linkers, a more irregular structure of the cross-linkers resulted in the better vibration isolation performance of the PUEs.

“…The inhibition effect increased with the increasing concentration of CS. In another work, Naz et al (2018) synthesized CS-based waterborne polyurethane (CS-WPU), which was carried out in two steps. The PU-prepolymers were formed through the reaction between hexamethylene diisocyanate (HDI), PEG (Mw = 6 kDa), and DMPA.…”

Marine-derived chitosan has been widely examined for its use in developing biomedical materials. Not only is it non-toxic, biocompatible, and degradable, it has also shown unique antimicrobial properties. The antimicrobial properties of chitosan are restricted by neutral and physiological conditions because it is insoluble in water and its pKa values is 6.5. One solution to this problem is to graft chemically modified groups onto the backbone of chitosan. The aim of this paper is to review the mode of antimicrobial action of chitosan and chitosan derivatives. Using chitosan alone may not meet the demands of various applications. However, the introduction of additional polymers and antimicrobial agents is commonly used to enhance the antimicrobial potential of chitosan-based biomaterials. Chitosan-based composite biomaterials have been developed that allow diversified formulations to broaden applications, including nanoparticles, hydrogels, films, sponges, fibers, or even microspheres. These along with recent advances on chitosan-based composite biomaterials used for wound healing, food packaging, textile sector, 3D printing and dental materials, were reviewed in detail.

Huge amounts of chitin and chitosans can be found in the biosphere as important constituent of the exoskeleton of many organisms, as well as waste by worldwide seafood companies. Nowadays, politicians, environmentalists, and industrialists encouraged the use of these marine polysaccharides as renewable source, particularly when developed by alternative eco-friendly processes, especially in the production of regular cosmetics. The aim of this review is to outline the physicochemical and biological properties and the different bioextraction methods of chitin and chitosans sources, focusing on enzymatic deproteinization, bacteria fermentation, and enzymatic deacetylation methods. Thanks to their biodegradability, non-toxicity, biocompatibility, and bioactivity, the application of these marine polymers is widely used in the contemporary manufacturing of biomedical and pharmaceutical products. In the end, advanced cosmetic products based on chitin and chitosans are presented, analyzing different therapeutic aspects about skin, hair, nail, and oral care. The innovative formulations described can be considered as excellent solutions regarding problems in the various body anatomical sectors.
