“…Reacting with the hydroxyl groups and then modifying the different chemical functional groups are two of the essential mechanisms to improve the chemical bonding of the composite materials. 1,[99][100][101] The important chemical treatments are alkalization, 102 etherification, 103,104 quaternization, 105 isocyanation, 106,107 amidation, 108,109 acylation, 110 cyanoethylation, 111 and silanization. 112 Komal et al 113 evaluated different behavior of banana fiber when they were treated through an alkaline medium.…”

Bast fibers such as flax, hemp, and jute‐reinforced polymer composites due to their exceptional properties are gaining significant demand as a sustainable and cost‐effective alternative to conventional synthetic fiber‐reinforced composites. This comprehensive study aims to shed light on the potential of bast fiber reinforced composites (BFRCs) as innovative materials for various industrial applications. The manuscript presents a comprehensive discussion on bast fibers, polymer matrices, and the fabrication techniques employed to produce BFPCs, highlighting the effects of different modification techniques on the resulting mechanical properties. Industrial and structural applications of BFPCs are explored, with a specific focus on their use in the automotive and aerospace industries, construction materials, and sporting goods. Finally, the manuscript concludes with a discussion of the challenges and future prospects of BFPCs. This manuscript can serve as a valuable resource for researchers, engineers, and professionals interested in the emerging field of bast fiber‐reinforced polymer composites. It opens new frontiers in material design and highlights the enormous potential of BFPCs to revolutionize industrial applications through their exceptional mechanical properties.Highlights Materials and processing of fiber‐reinforced polymer nanocomposites.

It was for the first time we attempted to develop zinc and cadmium incorporated linseed oil based poly(esteramide-urethane) [Zn/Cd-LPEAUr], and investigated their structure, mechanism, and properties. The resin was synthesized in situ by the reaction of linseed oil derived fatty amide diol [HELA], divalent zinc/ cadmium acetate and toluylene-2, 4 (6), diisocyanate [TDI; 2-12 wt %] with minimal solvent. The structural elucidation of Zn/Cd-LPEAUr was carried out by FTIR, 1 H-NMR, and 13 C-NMR spectral techniques. TGA and DSC techniques were used to measure the thermal stability and curing behavior of these resins, respectively. The physicomechanical and chemical/corrosion resistance properties were investigated by standard laboratory methods. The performance of Zn/Cd-LPEAUr coating was compared with reported oil based polyesteramide. Antibacterial test of the resins were performed by agar diffusion method against E. coli and S. aureus, and compared with those of petroleum-based metal containing polyurethanes.

Various polyrotaxane modification reactions, such as methylation, hydroxy propylation, tritylation, acetylation, trimethylsilylation, phenylcarbamation, dansylation, and nitration, were examined to obtain polyrotaxane derivatives, in which various functional groups were attached to cyclodextrin moieties. Although the nitrate could not be obtained because of significant degradation of the polyrotaxane under the conditions examined, other derivatives were successfully prepared under moderate conditions. The introduction of these functional groups and their degree of substitution were assessed with Fourier transform infrared and NMR spectroscopy. The polyrotaxane derivatives thus obtained were soluble in various organic solvents other than the conventional solvents (dimethyl sulfoxide and aqueous NaOH) used for the unmodified polyrotaxane. That is, the solubility of the polyrotaxane was drastically changed by the examined modification reactions. © 2006 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 44: 6312–6323, 2006
