“…In particular, with the increasing availability of nanometric biomolecules, such as the CNs [75,171] or the cellulose nanowhiskers [119], these problems were amplified due to the increase in the surface area. Consequently, high energetic dispersion and homogenization techniques, such as the ultraturrax homogenization [172,173], sonication [174,175] and high pressure homogenization (HPH) [176,177], were increasingly applied. If the operative parameters and the homogenization techniques did not allow an optimal wet coating to be prepared, the use of biosurfactant [178,179] or a bio-based primer [180][181][182] becomes necessary.…”

The development of new bio-based coating materials to be applied on cellulosic and plastic based substrates, with improved performances compared to currently available products and at the same time with improved sustainable end of life options, is a challenge of our times. Enabling cellulose or bioplastics with proper functional coatings, based on biopolymer and functional materials deriving from agro-food waste streams, will improve their performance, allowing them to effectively replace fossil products in the personal care, tableware and food packaging sectors. To achieve these challenging objectives some molecules can be used in wet or solid coating formulations, e.g., cutin as a hydrophobic water- and grease-repellent coating, polysaccharides such as chitosan-chitin as an antimicrobial coating, and proteins as a gas barrier. This review collects the available knowledge on functional coatings with a focus on the raw materials used and methods of dispersion/application. It considers, in addition, the correlation with the desired final properties of the applied coatings, thus discussing their potential.

“…The thermal properties of composites comprising of nanochitin have been analyzed by numerous researchers with the aid of thermo gravimetric analysis (TGA) and differential scanning calorimetry (DSC) [80][81][82] usually under a nitrogen atmosphere [80,[83][84][85][86].…”

“…This restructuring is apparent above 5 wt % of CNFs. In a study conducted by Xu et al, the compositions, thermal stabilities and decomposition kinetics of TEMPO-oxidized cellulose nanofiber (TOCNF), partially deacetylated α-chitin nanofiber (α-DECHN) and TOCNF/multi-wall carbon nanotube (MWCNT)/α-DECHN composite wires were analyzed by TGA [85]. As shown in the above Figure 17, the preliminary phase of the thermal decomposition of TOCNF/MWCNT/α-DECHN composite wire is consistent with that of TOCNFs.…”

“…It was also observed that the system performance and stability were also improved with the help of chitin nano fibers. Conductive biomass-based composite wires with cross-linking anionic nanocellulose and cationic nanochitin as scaffolds were developed by Xu et al, who efficiently designed a collection of conductive composite wires by coupling dispersions of multi-wall carbon nanotubes (MWCNTs) and TEMPO-oxidized cellulose nanofibers (TOCNFs) with specific MWCNT compositions into a dispersion of partly deacetylated α-chitin nanofibers (α-DECHNs) proceeded with a drying procedure [85]. When the content of MWCNTs exceeded 14 wt %, the designed composite wire could illuminate LED at 5 V voltage, demonstrating the enormous latency of this product based on biomass in conductive material deployment.…”

Industrial sea food residues, mainly crab and shrimp shells, are considered to be the most promising and abundant source of chitin. In-depth understanding of the biological properties of chitin and scientific advancements in the field of nanotechnology have enabled the development of high-performance chitin nanomaterials. Nanoscale chitin is of great economic value as an efficient functional and reinforcement material for a wide range of applications ranging from water purification to tissue engineering. The use of polymers and nanochitin to produce (bio) nanocomposites offers a good opportunity to prepare bioplastic materials with enhanced functional and structural properties. Most processes for nanochitin isolation rely on the use of chemical, physical or mechanical methods. Chitin-based nanocomposites are fabricated by various methods, involving electrospinning, freeze drying, etc. This review discusses the progress and new developments in the isolation and physico-chemical characterization of chitin; it also highlights the processing of nanochitin in various composite and functional materials.
