With their low cost and unique physicochemical properties, conductive polymer‐ based film electrodes drew much attention in flexible electronic devices. However, their poor intrinsic conductivities limit their applications in high‐rate supercapacitors or high electromagnetic interference (EMI) shielding performance. It is meaningful to deal with the issue through the rational design of the film nanostructure. Herein, using specially treated PEDOT:PSS coated polyacrylonitrile (PAN) nanofibrous films (PPNFs) as a current collector, polyaniline (PANI) or polypyrrole (PPy) based highly crosslinked conductive nanofibrous films (HCC‐NFs), named as PANI@PPNF and PPy@PPNF, are fabricated. The PANI@PPNF electrodes exhibit a specific capacitance of 156 mF cm–2 at a current density of 1 mA cm–2. Meanwhile, 41% capacity (64 mF cm–2) remained even at 20 mA cm–2. The remarkable rate performance of PANI@PPNFs demonstrates the HCC‐NF structure brings a high‐rate character for pseudocapacitive material. Furthermore, the solid‐state supercapacitor shows long‐term cycle stability at a high scan rate of 1 V s–1 for 5 000 cycles and over 75% of the specific capacitance is retained, suggesting excellent cycle stability of PANI@PPNF. Besides, PANI or PPy based HCC‐NFs show high performance in EMI shielding. This conductive polymer‐based HCC‐NF structure offers a promising platform for designing multi‐functional flexible electronic devices.

“…Graphene oxide (GO), a single layer of graphite oxide bearing oxygen functional groups on its basal side and boundary zone, has already attracted tremendous interest in the domain of polymer composite science on account of its plentiful oxygen-containing functional groups [ 17 , 18 ]. Compared to other carbon fillers, such as carbon nanofibers and carbon nanotubes, its high special surface area, excellent wettability, low cost, large-scale preparation, and remarkable mechanical properties make GO the optimal material for next-generation hierarchical reinforcements of polymer composites [ 10 , 19 , 20 ]. Recently, some studies have been devoted to chemically grafting GO onto the CF surface to realize the interface enhancement.…”

This study focused on the faint interface bonding between carbon fiber (CF) and poly(phthalazinone ether ketone) (PPEK) thermoplastic, a multistage hybrid interface layer was constructed via the condensation reaction of N-[3-(Trimethoxysilyl)propyl]-N,N,N-trimethylammonium chloride (KHN+) and the electrostatic adsorption of graphene oxide (GO). The influence of the contents of GO (0.2 wt%, 0.4 wt%, 0.6 wt%) on the interfacial properties of composites was explored. FTIR, Raman spectra, XPS tests indicated the successful preparation of CF-KHN+-GO reinforcements. The multistage hybrid interface layer significantly increased fiber surface roughness without surface microstructure destruction. Simultaneously, polarity and wettability are remarkably improved as evidenced by the dynamic contact angle experiment. The interlaminar shear strength (ILSS) and flexural strength of the CF/PPEK composites with 0.4 wt% GO (CF-KHN+-4GO) were 74.57 and 1508 MPa, which was 25.2% and 23.5% higher than that of untreated CF/PPEK composite, respectively. Dynamic mechanical analysis proved that CF/GO/PPEK composites have excellent high-temperature mechanical properties. This study furnishes an unsophisticated and valid strategy to build an interface transition layer with a strong binding force, which would offer a new train of thought in preparing high-performing structural composites.

“…13 The chemical inertness due to the existence of the high temperature carbonization/ graphitization step during manufacturing, the surface lipophobicity, and excessive smoothness and less adsorption characteristics of carbon fibers lead to weaker bonding with matrix materials. [14][15][16] A great deal of scientific researches have been performed on the surface modification of carbon fibers, primarily categorized as plasma treatment, 17 electrochemical oxidation, 18 chemical grafting, 19 electrophoretic deposition (EPD) 20 and chemical vapor deposition (CVD). 21 These methods could be classified into oxidative and nonoxidative treatments.…”

Carbon fibers were surface treated with supercritical water/nitrate system to improve the interfacial adhesion of the carbon fiber/epoxy composite. The surface chemistry analysis showed that oxygen functional groups on the surface of the carbon fibers increased after treatment, which were mainly carbonyl and carboxyl groups. The surface microstructure observation indicated that the treatment obviously increased the surface roughness of the carbon fibers. Surface energy of the treated carbon fibers also increased. The increased functional groups, surface roughness and surface energy were beneficial to enhance the interfacial adhesion of the carbon fiber/epoxy composite. Compared with the untreated carbon fibers, the strength loss of the treated carbon fibers was less than 3% and the other mechanical properties were almost unchanged. The caclulated interfacial fracture energy and the interfacial shear strength of the treated carbon fiber/epoxy composite were enhanced by 19% and 29%, respectively, compared with the untreated carbon fiber/epoxy composite. In summary, supercritical water/nitrate treatment is a potential method for changing the inert surface of carbon fibers to improve the interfacial adhesion between carbon fibers and matrix.
