“…On the other hand, better wetting can enhance the IFSS by improving the work of adhesion, high surface energy indicates that fiber contains more polar groups on the surface, interfacial adhesion can be improved by the strong interaction between resin and the polar groups. 1,2 PPESK is a kind of novel thermoplastic (the structure is shown in Fig. 1), compared with traditional thermoplastic [3][4][5][6] (such as: PEEK, PES, PEI), it has excellent thermal resistance property (T g ¼ 2878C), besides it can be dissolved in usual solvents (such as DMAc, NMP, and chloroform), thus fibers-reinforced PPESK composite can be prepared through solution impregnation technique.…”

Interfacial adhesion between fiber and matrix has a strong influence on composite mechanical performance: better interfacial adhesion can enhance composite transverse properties, flexural properties, and interlaminar shear strength, and so on. To exploit the reinforcement potential of the fibers in advanced composite, it is necessary to reach a deeper understanding on the relation between fiber wettability and interfacial adhesion. In our experiment, we study the influence of fiber wettability on interfacial properties of fiber/PPESK composites by choosing three kinds of fibers with different wettabilities. The relation between fiber wettability and surface free energy was discussed, and the influence of fiber wettability on the interfacial property of fiber/PPESK composites was analyzed. Results indicate that higher surface free energy can enhance the wettability between fiber and matrix, and the humid resistance and interfacial adhesion can be improved at the same time.

“…The surface energies of the three components are listed in Table 2 [19][20][21]. Consequently, the wetting coefficient of the polymer blend system containing n-ZnO particles is estimated to be 3.59, which predicts that n-ZnO particles will be preferentially incorporated into the BMI-rich phase.…”

Phase-separated polymer blend composite films exhibiting high thermal diffusivity were prepared by blending a soluble polyimide (BPADA-MPD) and a bismaleimide (BMI) with needle-shaped zinc oxide (n-ZnO) particles followed by high-temperature curing at 250 • C. Images recorded with a field-emission scanning electron microscope (FE-SEM) equipped with wavelength-dispersive spectroscopy (WDS) demonstrated that the spontaneously separated phases in the composite films were aligned along the out-of-plane direction, and the n-ZnO particles were selectively incorporated into the BMI phase. The out-of-plane thermal diffusivity of the composite films was significantly higher than those of the previously reported composite films at lower filler contents. Based on wide-angle X-ray diffraction (WAXD) patterns and image analysis, the enhanced thermal diffusivity was attributed to the confinement of the anisotropically shaped particles and their nearly isotropic orientation in one phase of the composite films.

“…The surface free energy and work of adhesion of the CFs increased after electrochemical oxidation treatment. If the value of the polar component after the treatment is high, many hydrophilic groups such as hydroxyl (-OH), carbonyl (C=O), carboxyl (-COOH), and amine (-NH 2 ) can exist on the fiber surface [37]. Meanwhile, an increase of dispersive components is possible due to the increase of specific surface area due to the roughness change after the treatment.…”

In this work, we studied the effects of electrochemical oxidation treatments of carbon fibers (CFs) on interfacial adhesion between CF and epoxy resin with various current densities. The surface morphologies and properties of the CFs before and after electrochemical-oxidation-treatment were characterized using field emission scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and single-fiber contact angle. The mechanical interfacial shear strength of the CFs/ epoxy matrix composites was investigated by using a micro-bond method. From the results, electrochemical oxidation treatment introduced oxygen functional groups and increased roughness on the fiber surface. The mechanical interfacial adhesion strength also showed higher values than that of an untreated CF-reinforced composite.
