Summary: This paper compares different methods of hydrophobization of cotton fabrics using the thio-ene click reaction and demonstrates the easy production of durable, superhydrophobic textiles. Functionalized silsesquioxanes are used for the hydrophobization, with alkoxysilyl, alkyl, and fluoroalkyl moieties introduced as functional groups. Different methods and stages are employed to prepare samples, and the hydrophobicity of the fabric is evaluated using water contact angle measurements. The samples are also analyzed using infrared analysis, scanning electron microscopy, and elemental analysis.

Summary: Multifunctional cotton fabric was prepared by coating AgBr-TiO2/OV-POSS nanocomposites using the spray coating method. The presence of AgBr-TiO2 nanoparticles and OV-POSS resulted in increased surface roughness and adhesion, leading to enhanced hydrophobicity and decreased surface energy of the fabric. The coated fabric exhibited excellent mechanical durability, chemical resistance, UV protection, self-cleaning properties, oil/water separation efficiency, methylene blue degradation, and antibacterial efficacy against K. pneumoniae and S. aureus.

Summary: This study reports a simple method to prepare hydrophobic and UV-resistant multifunctional colored cotton fabrics by using the self-curing technique of cationic polyethyleneimine dye polymer (CPNP(R218)) nanospheres. The CPNP(R218) nanospheres were synthesized and formulated into polymer membranes on the surface of cotton during the dyeing process. The dyed cotton fabric showed good color properties and hydrophobicity, with a static water contact angle (WCA) of 138.4 degrees. The UV protection factor (UPF) value of the dyed cotton was significantly higher than that of the original cotton fabric, indicating the potential of this self-curing film formation method for the construction of multifunctional colored cotton fabrics.

Summary: Surface functionalization of cotton fabric was achieved using novel bifunctional polyolefins with different pendant groups, leading to successful hydrophobization and proven durability. The impact of functional group type and side group type on surface properties was demonstrated, with fluoroaryl groups ensuring the highest water contact angle. Thermal stability of the treated cotton fabric was unaffected by the applied modifiers. Additionally, the flame-retardant properties of the polyolefin-coated cotton were verified and discussed in this first report on the application of organofunctionalized bifunctional polyolefins as surface modifiers for cotton fabrics.

Summary: A sandwich-like structured nanocoating system was developed in this study to provide natural polymer fabrics with flame retardancy and wash durability through various interactions. The concentration of bPEI in the coating system affects the wash durability of the fabrics, with higher concentrations leading to better wash durability but also potentially sacrificing flame retardant performance. The systematic evaluations post washing demonstrate that the coating system can maintain a balance between wash durability and flame retardancy.

Summary: We have developed a convenient process to prepare multifunctional colored cotton fabrics with hydrophobic and UV resistant properties using self-curing raspberry-shaped colored nanospheres and PMHS. The synthesized SiO2@DPBA nanospheres effectively prevent the leakage of disperse dyes, and the monodisperse SiO2@DPBA nanospheres provide excellent color performance. By applying a transparent hydrophobic coating on the surface of the cotton fabric using PMHS, the colored cotton fabric achieves high hydrophobic angle and UPF value, and exhibits good mechanical and chemical stability under various environmental conditions. This synergistic interaction between colored nanoparticles and PMHS offers an easy and feasible approach for the fabrication of multifunctional dyed textiles.

Summary: A metallaphotoredox-catalyzed strategy for the aminocarbonylation of alkynes with amines and CO has been developed. This method allows for selective synthesis of alpha,beta-unsaturated amides and a sequential four-component hydroaminocarbonylation/radical alkylation, demonstrating great potential in the selective and divergent functionalization of alkynes. Preliminary mechanistic studies suggest a photoinduced oxidative insertion of aniline and CO into nickel followed by a migratory insertion of (carbamoyl)nickel species may be involved.
