Creation of a high strength, hydrophobic and fireproof surface on wood by polyamide acid under mild and simple conditions Prog. Org. Coat. (IF 6.6) Pub Date : 2024-02-14 Guilin Ren, Yiqun Fang, Ruofan Yang, Jinghan Zhu, Yiqing Fu, Weihong Wang, Rongxian Ou, Yongming Song, Qingwen Wang
A high performance surface for balsa wood (BW) and delignified balsa wood (DW) was created using a two-step synergistic strategy of impregnation and layer by layer coating by polyamide acid (PAA). The results showed that the PAA synthesized from 3,3,4,4-biphenyltetracarboxylic acid dianhydride (S-BPDA) and 4,4′-diaminodiphenyl ether (ODA) was the optimal choice for the surface of wood due to its exceptional

Boosting the conductivity of water/alcohol processable cathode interface layer via Ti3C2 doping for efficient organic solar cells Prog. Org. Coat. (IF 6.6) Pub Date : 2024-02-14 Gaoyang Wang, Yi-Lin Liu, Zhenye Li
Poly(9,9-bis(3′-(,-dimethyl)-Nethylammonium-propyl-2,7-fluorene)-alt-2,7- (9,9-dioctylfluorene)) dibromide (PFN-Br) has been widely used as an cathode interface layer (CIL) for efficient organic solar cells (OSCs) because of its straightforward solution processability, excellent electron extraction ability, as well as prominent compatibility with various OSCs systems. However, the relatively low conductivity

Enhancement of antimicrobial and UV resistant properties of aramid III fiber through surface coating Prog. Org. Coat. (IF 6.6) Pub Date : 2024-02-14 Bo Zhou, Xuyi Wang, Ziang Wang, Ou Zhang, Yuanzhang Jiang, Lin Tan
Aramid III fiber is a typical high-performance fiber with the advantages of high strength and high modulus, as well as excellent thermal stability, which has been extensively applied in both civil and military fields. However, microbial proliferation and UV irradiation can reduce its mechanical properties and the subsequent service life. Herein, a novel antimicrobial and UV-resistant aramid III fiber

Solvent-free coatings based on bio-sourced benzoxazines resins with healing, repair, and recycling capabilities Prog. Org. Coat. (IF 6.6) Pub Date : 2024-02-14 Louis Van Renterghem, Roya Malekkhouyan, Leila Bonnaud, Romain Tavernier, Marjorie Olivier, Jean-Marie Raquez
Conventional benzoxazine resins, in spite of their excellent thermo-mechanical properties and good solvent resistance, suffer from high curing temperatures and limited self-healing/ reprocessability. In this frame, bio-sourced phenol (Phloretic acid), various diols (Dodecandiol/PEG200/Ethylene glycol), and amine (monoethanolamine) have been used in appropriate proportions to synthesize innovative benzoxazine

Hybrid aliphatic and aromatic diisocyanates forming mixed urea segments for high-performance polyurea Prog. Org. Coat. (IF 6.6) Pub Date : 2024-02-12 Khanisya Palaniandy, Sheik Ambarine Banon Auckloo, Giuseppe Cavallaro, Giuseppe Lazzara, Eng-Seng Chan, Pooria Pasbakhsh
Polyurea is gaining more traction in the realm of protective coatings on metal surfaces from corrosion. The properties of polyurea can be controlled by the judicious selection of its reactants. Herein, a series of polyurea based on hybrid aliphatic/aromatic diisocyanates are synthesized from isophorone diisocyanate (IP) and polycarbodiimide-modified diphenylmethane diisocyanate (ISO). The formulation
