“…[15][16][17] Recently, polydopamine (PDA) as a sizing agent for fiber surface modification is greatly appealing to researchers. [18][19][20][21] PDA coating exhibit outstanding adhesive properties and can stick to different material surfaces, such as metals, fibers, semiconductors, ceramics, glass, and even PTFE. [22] It has been reported that PDA layers are formed quickly through an oxidationpolymerization process of dopamine (DA) under moderate conditions.…”

To gain better interfacial and mechanical performances of carbon ber reinforced epoxy resin (CF/EP) composites, the surface modi cation of CF was carried out via a simple mild method. The polydopamine (PDA) was applied to size the CF, as well as the in uence of PDA sizing time on CF were elucidated. As the PDA deposited time increases, a growing number of PDA nanoparticles were adhered on CF surface, associating with appearance of PDA agglomerates. Through analyzing the results, the optimum PDA sized time was 24 h. The introduction of PDA increase the chemical reaction and mechanical interlocking between ber and matrix. Compared with unsized CF, the tensile strength of PDA 24 h sized CF was improved by 27.0%, the interlaminar shear strength, exural and impact strength of PDA 24 h sized CF/EP composites increased by 103.7%, 65.6% and 163.6%, respectively. Furthermore, the fracture topographies of CF/EP composite strikingly implied that the PDA has a positive impact on the mechanical performances of CF/EP composites.

Carbon fiber (CF) reinforced epoxy (EP) matrix composite was widely used in industries, however, the mismatch of modulus between CFs and resin would lead to easy damage at the composite interface. In addition, complex modification methods limited the application of CF composite. To address these problems, a simple and efficient physical coating method was used to introduce a degressive gradient modulus layer on the CF surface. The “stepped modulus” structure could effectively disperse stress, improve the mechanical interlocking and wettability, and realize the modulus matching between fiber and resin, thus significantly improving the interface properties of the composites. The interfacial properties of Cn‐CNT‐CF/EP (n was the number of coatings) were gradually improved with the controllable gradient modulus layer established. The interlaminar shear strength (ILSS) and transverse fiber bundle (TFB) strength of C4‐CNTs‐CF/EP were increased by 65.7% and 85.6%, respectively. Due to the presence of a “degressive gradient” modulus layer, the improved mechanical properties of the Cn‐CNT‐CF/EP were comparable to or even more significant than other complicated approaches found in the literature. This simple and effective composite interface construction technique laid the theoretical and practical foundation for the preparation of high‐performance CF composite.

“…Polydopamine (PDA) formed by dopamine (DA) under a weak alkaline environment can adhere to almost all types of materials, such as ceramics, metals, organic materials, and inorganic materials 29–32 . Therefore, dopamine has been widely used to modify the surface of high‐performance fibers, such as nylon fiber, 33 aramid fiber, 34 carbon fiber 35–37 . However, the reports of using DA in the dipping system are limited.…”

Considering the toxicity of traditional resorcinol‐formaldehyde‐latex (RFL) dipping solution used to prepare fiber‐ reinforced rubber composites, a novel eco‐friendly dopamine (DA)‐supported dipping system was developed in this study. Based on the interactions between DA, glycerol triglycidyl ether (GTE), and m‐xylylenediamine (MXDA), the dipping solution successfully coated the surface of the nylon‐66 (PA66), and the resulting GTE/DA/MXDA/latex‐treated PA66 (PA66‐GDML) possessed better thermal stability than untreated PA66. The interfacial adhesion between PA66 and neoprene was significantly improved by using the appropriate interfacial layer and the synergistic effect during co‐vulcanization. The adhesive strength between PA66‐GDML and neoprene was comparable to that obtained in an RFL system, especially when the ratio of GTE/DA/MXDA was 5:1:2.Highlights An eco‐friendly dopamine‐supported dipping system was developed. The dipping solution (GTE/DA/MXDA) could successfully coat nylon 66 fibers. Treated nylon 66 possessed better thermal stability than untreated nylon 66. The adhesive strength was comparable to that obtained in a RFL system. The new dipping system shows great potential to replace RFL system.
