Flexible conductive glass fibers have received significant attention due to their potential applications in electronics, semiconductors, batteries, and automobile and aerospace industries. In this study, highly flexible conductive fibers composed of internal glass fibers and external nanocarbon coatings were fabricated. A conductive nanocarbon-coated glass fiber (NCGF) was prepared by a simple polymer pyrolysis deposition method. The resistance per centimeter of the fiber is approximately 10 5 Ω, and the conductivity of the fiber nanocarbon coating is approximately 10 5 S/ m. The coating is dense and extremely smooth, and the contact interface between the coating and the glass fiber is compact tightly. Meanwhile, the density functional theory (DFT) is used to further analyze the interface bonding between the coating and the glass fiber and the conductive mechanism of the nanocarbon-coated glass fiber.

Carbon fibers have promising applications in the efficient transmission of electric power with less resource consumption. Laser graphitization of the mesophase pitch-based carbon fiber (MPCF) was proposed to improve the electrical conductivity of the carbon fiber. The obtained MPCF showed a high conductivity of 7.04 × 105 S/m. The graphitization degree of carbon fiber increased and the interlayer spacing of its graphite crystal decreased on increasing the laser intensity. With a laser power of 360 W and an irradiation period of 25 s, corresponding to a temperature of 3001 °C, a high graphitization degree (R = 0.02) was obtained and the interlayer spacing was as small as 0.338 nm, close to that of pure graphitic carbon (0.335 nm). The enhanced electrical conductivity is attributed to the improved homogeneity of graphitization along the axial and radial directions, the ordered structural evolution, ordered stacking of the graphitic layer, and the promoted connectivity between the graphitic crystals in the carbon fiber. The energy consumption of the proposed method is estimated to be only 0.46% of that with the conventional Joule heating approach. This work suggests that laser-induced graphitization is a good alternative to prepare carbon fibers with high electrical conductivity and reduced energy consumption.

Steam generation through efficient utilization of solar energy is a promising technology in addressing the challenge of global freshwater shortage and water pollution. One of the biggest hurdles for traditional photothermal membranes to function continuously in a high temperature, high salt, and corrosive environment has been attributed to their rapid decline of mechanical properties. In this work, a highly efficient solar-driven interfacial water evaporation system has been developed via a polydopamine/carbon/silicon (PCS) composite membrane supported by a floating insulation foam substrate. A 3.1 fold increase in the water vaporization rate was recorded compared with the pure water system. The 2D-carbon nanolayer on the surface was successfully prepared by carbonizing low-cost linear polyethylene with a glass fiber (GF) membrane as the substrate, and then the carbon membrane was modified with dopamine to control water transport on the carbon coating and within the glass fiber. The PCS membrane has a high efficiency for solar steam generation owing to high optical absorption and has excellent solar thermal conversion capability. The evaporation rate and solar thermal conversion efficiency of the PCS membrane under simulated sunlight irradiation with 1 sun (1 kW·m–2) are 1.39 kg·m–2·h–1 and 80.4% respectively, which are significantly higher compared to GF membrane, carbon/silicon (CS) membrane, and pure water without a photothermal membrane. The water evaporation system retained high efficiency after 20 cycles under simulated sunlight irradiation of 1 sun. This study provides critical insight on the design and fabrication of a highly efficient and durable evaporation system.
