Chitosan is a polysaccharide comprised of linked D-glucosamine and N-acetyl-D-glucosamine units. It is produced by the deacetylation of chitin, a naturally occurring polysaccharide. Chitosan is commercially used in agriculture as a biopesticide but has potential applications in the biomedical field due to its antibacterial properties. This product is derived from shrimp shell.

A flame retarded chitosan binder for insulating miscanthus/recycled textile fibers reinforced biocomposites
Roland El Hage, Yasmina Khalaf, Clément Lacoste, Michel Nakhl, Patrick Lacroix, Anne Bergeret
Journal of Applied Polymer Science, 47306, 136 (2018)

he main objective of this study is devoted to the development of new insulating and ignifuged miscanthus fibers (Mf)/recycled textile fibers (RTf) reinforced biocomposites (BCs) using chitosan as polysaccharide-based binder and aluminum trihydroxide (ATH) fillers while focusing on the fire behavior… read more

New bio-based phosphorylated chitosan/alginate protective coatings on aluminium alloy obtained by the LbL technique
Clément Coquery, Federico Carosio, Claire Negrell, Nicolas Caussé, Nadine Pébère, Ghislain David,
Surfaces and Interfaces, 59-66, 16 (2019)

Bio-based coatings were obtained by the layer-by-layer (LbL) technique from a native chitosan (Mw ≈ 30,000 g mol−1) or from two synthesized phosphorylated chitosan of different molecular weights (Mw ≈ 30,000 g mol−1 and Mw ≈ 250,000 g mol−1) combined with alginate and used for corrosion protection … read more

Two grades of chitosan [chitosan 30000 g mol−1 (N-chitosan 30) and 250000 g mol−1 (N-chitosan 250)] were functionalized by the Kabachnik–Fields reaction. To obtain the highest phosphonic ester grafting rate (55% and 40% for the N-chitosan 30 and N-chitosan 250, respectively); the pH must be kept co… read more

Influence of agricultural fibers size on mechanical and insulating properties of innovative chitosan-based insulators
Yasmina Khalaf, Peter El Hage, Julia Dimitrova Mihajlova, Anne Bergeret, Patrick Lacroix, Roland El Hage

This work is dealing withthe use of miscanthus, recycled textile and rice husks as reinforcement for chitosan matrix to elaborate new insulating composites for building application. Insulating composites having thermal conductivity of 0.07–0.09 W.m−1.K−1and density of 350–400 Kg.m−3were manufacture… read more

pH-Sensitive Chitosan Nanoparticles for Salivary Protein Delivery
Yi Zhu, Lina M. Marin, Yizhi Xiao, Elizabeth R. Gillies, Walter L. Siqueira
Nanomaterials, 1028, 11(4) (2021)

Salivary proteins such as histatins (HTNs) have demonstrated critical biological functions directly related to tooth homeostasis and prevention of dental caries. However, HTNs are susceptible to the high proteolytic activities in the oral environment. Therefore, pH-sensitive chitosan nanoparticles … read more

Chitin and Its Derivatives: Nanostructured Materials from Different Marine and Terrestrial Sources

Chemical Engineering Transactions, 295-300, 93 (2022)

Chitin is a very abundant polysaccharide that can be obtained from well-known marine sources (crustaceans), but also from terrestrial sources (mushrooms and insects). In the case where animal sources are considered, the material can be obtained by much abundant food or feeding waste. The extraction… read more

Prediction of coating thickness for polyelectrolyte multilayers via machine learning
Varvara Gribova, Anastasiia Navalikhina, Oleksandr Lysenko, Cynthia Calligaro, Eloïse Lebaudy, Lucie Deiber, Bernard Senger, Philippe Lavalle & Nihal EnginVrana
Scientific Reports, 18702, 11 (2021)

Layer-by-layer (LbL) deposition method of polyelectrolytes is a versatile way of developing functional nanoscale coatings. Even though the mechanisms of LbL flm development are well-established, currently there are no predictive models that can link flm components with their fnal properties. The cu… read more
