“…Meanwhile, the sizing or coating treatment can enhance the roughness of ber surface and introduce the interface layer, which advance the stress transfer to the CF [12][13][14]. More importantly, ber sizing or coating is a convenient and effective method without any loss of ber inner properties [15][16][17]. Recently, polydopamine (PDA) as a sizing agent for ber surface modi cation is greatly appealing to researchers [18][19][20][21].…”

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.

“…As a result, the high thermal conductivity requirements of integrated devices cannot be met. However, the thermal conductivity can be improved by adding high thermal conductivity fillers such as graphene oxide (GO) [9][10][11][12] to the polymer matrix. GO is commonly used in TIM applications because of its low density and high thermal conductivity.…”

The thermal path must be properly configured to improve the thermal properties of polymer composites. Three-dimensional (3D) thermally conductive networks can be used as an excellent means for building high-speed conductive pathways in polymer composites. Titanium dioxide (TiO 2 ) nanowire (NW)/reduced graphene oxide (rGO)/ epoxy (EP) composite material has a 3D foam structure and focuses on TiO 2 NW formation and rGO gelation through a hydrothermal process.

“…Because of its particular strength, high stiffness, and resistance to acid erosion, carbon fiber (CF) reinforced polymer composites are widely used in the aerospace, renewable energy, and sporting events, among others. − Composite interfaces have a key part in determining the overall property composites. − Poor wettability, limited physical–chemical interactions, and smooth surface of CFs prevent the formation of a strong contact. − In recent years, the multiscale reinforcement structures constructed by nanomaterials to enhance the comprehensive properties of composites have attracted great interest. − Due to its extremely efficient interface, graphene oxide (GO) is regarded as a viable option for preparing high-performance composites, great chemical activities, and exceptional mechanical properties. − …”

The development of nano-reinforced materials to form structural composites relies on controlling interfaces between nanomaterials and the bulk material to yield materials that can be applied in fields such as aerospace, wind power energy, and transportation. This paper describes experiments to design and control micro−nano multi-scale interfacial reinforced composites of carbon fiber using electrodeposition and electropolymerization in a one-step method. First, the adhesion of graphene oxide (GO) nanosheets on the fiber surface was effectively enhanced through the simultaneous deposition of GO nanosheets and electro-grafting of monomers. The deposition efficiency of GO nanosheets was significantly boosted with polymerization of monomers. The interlaminar shear strength and interfacial shear strength of the composites treated for only 120 s were increased from 40.8 and 50.5 to 54.6 and 73.9 MPa, an increase of 33.8 and 46.3%, respectively. Investigation of the mechanism of failure of the composites showed that it was due to the cohesive failure of the resin from interfacial debonding. This paper reports a theoretical and experimental basis for the continuous preparation of nano-reinforced carbon fiber and high-performance advanced composites.
