In situ creation of aramid fiber surface coating with polymerizable deep eutectic solvents and their interfacial bonding properties with rubber
Study on the interfacial bonding properties of AF and NR composites.The coating was created on the surface of aramid fibers (AFs) by solution dip?coating and in situ UV curable method, using a polymerizable deep eutectic solvent (PDES), dissolved poly(ethylene imine), and poly(ethylene glycol) diacrylate (PEGDA). Fourier transform infrared spectroscopy and thermogravimetry confirmed the successful construction of the coating on the AF surface, which accounted for 12%–17% of the total fiber mass. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) images revealed a 2??m increase in fiber diameter and a maximum fiber surface average roughness (Ra) of 263.7?nm when the polyethyleneimine content was 0.5% (AF?PDES?0.5). Based on these results, H pull?out samples of fiber/rubber composites were fabricated. The results indicated that the H pull?out force of AF?PDES?0.5 samples increased by 109.74% than that of untreated fiber, and reached 12.92?N of the maximum strength. In summary, the method is simple, rapid, non?polluting, capable of continuous, and intelligent construction of coatings on the surface of AF. Thus, making it highly promising for application in the field of aviation tires.HighlightsUsing PDES, green, and low?carbon preparation processes.Solution dip?coating and UV reaction for improved reaction speed and workability.Quantitative of interface thickness and modulus using EDS and AFM.
