“…2 b) shows the unsaturated carbons on the aromatic ring and alkyl side chains of the cardanol moiety in the range of 112–157 ppm. The chemical shifts at 35–22 and 14.22 ppm are attributed to the carbons in the methylene and methyl groups of the alkyl side chains of cardanol 25 . The new peaks that appeared at 58.29, 18.28 and 43.29 ppm are attributed to the carbons in the –OCH 2 CH 3 and N–CH 2 – groups.…”

A novel eco-friendly halogen-free cardanol-based flame retardant with P, Si, and N on the chain backbone (PSNCFR) was synthesized and incorporated into phenolic foams (PFs). PSNCFR was comprehensively investigated via Fourier transform infrared spectroscopy and nuclear magnetic resonance. PSNCFR endowed PFs with flame retardancy, contributed to generating a composite char defense against flames, and efficiently prevented smoking from PFs. PSNCFR introduction improved the flexural strength of the PFs to approximately 155% of that of pristine PF. PSNCFR-modified PFs displayed a high limiting oxygen index value of 41.9%. The results of cone calorimeter show that the mean heat release rate, mean effective heat of combustion, and total heat release of the PSNCFRmodified PFs reduced by 26.92%, 35.71%, and 31.25%, respectively. In particular, the total smoke production of the PSNCFR-modified PFs decreased by 64.55%, indicating excellent smoke inhibition. As for the mechanism, the condensation and gas phases during pyrolysis were responsible for the synergistic flame retardancy in the modified PFs. The findings demonstrate that PSNCFR can be used in PF preparation to overcome their drawbacks of internal brittleness and flammability.

“…5 Cardanol is composed of a phenol group with an unsaturated 15-carbon side chain which can exhibit until three Thereby, the structure of the alkyl chain of cardanol could provide interesting coating properties such as flexibility, hydrophobicity, chemical resistance, flame retardant and anti-corrosion properties. 5,[10][11][12][13][14][15][16][17] Numerous of those studies focused on the introduction of acrylate-cardanol-based monomers in order to obtain ultra-violet (UV)-curable coatings. Li et al studied the formation of latex-based coatings with higher adhesion performance thanks to the incorporation of phosphonated acrylated cardanol monomers.…”

“…Cardanol methacrylate was used as additive for UV-curable tripropylene glycol diacrylate/1,6-hexanediol diacrylate formulations, to increase their hydrophobicity [ 22 ]. Acrylated cardanol diphenyl phosphate was added to urethane acrylate UV-curable coatings, enhance flame-retardant properties, and reduce volume shrinkage [ 23 , 24 ]. Finally, cardanol-based multi-arm acrylates, in which the acrylate groups are attached to the alkyl side chain of the cardanol moieties, were synthesized and used to produce UV-curable coatings [ 25 , 26 , 27 , 28 , 29 ].…”

Biobased monomers and green processes are key to producing sustainable materials. Cardanol, an aromatic compound obtained from cashew nut shells, may be conveniently functionalized, e.g., with epoxy or (meth)acrylate groups, to replace petroleum-based monomers. Photoinduced polymerization is recognized as a sustainable process, less energy intensive than thermal curing; however, cardanol-based UV-cured polymers have relatively low thermomechanical properties, making them mostly suitable as reactive diluents or in non-structural applications such as coatings. It is therefore convenient to combine them with biobased reinforcements, such as microfibrillated cellulose (MFC), to obtain composites with good mechanical properties. In this work a cardanol-based methacrylate monomer was photopolymerized in the presence of MFC to yield self-standing, flexible, and relatively transparent films with high thermal stability. The polymerization process was completed within few minutes even in the presence of filler, and the cellulosic filler was not affected by the photopolymerization process.
