In this study, we simulated the electric field distribution of side-by-side electrospinning by using the finite element method (FEM), and studied the effects of spinneret wall thickness, spinning voltage and receiving distance on the distribution of the electrostatic field. The receiving distance was selected as a variable in the experimental, a series of PAN/PSA composite nanofiber membranes were prepared by using a self-made side by side electrospinning device. The membranes were tested by Fourier-transform infrared (FTIR), thermogravimetric analysis (TG), and scanning electron microscope (SEM). The prepared membranes were also treated by high-temperature treatment, and the change of fiber diameter and conductivity of the membrane before and after high-temperature treatment were studied. It was found that the PAN/PSA carbonized nanofibers could achieve a better performance in heat resistance and conductivity at 200 mm receiving distance.

“…Most of the studies in TiC nanofibers, thus, were focused on TiC-C composites. [35][36][37][38] These issues with production of single-phase TiC smooth nanofibers found in the literature (Table 1) provided the motivation for this study. It is seen in Table 1 that a variety of carbon sources and methods have been employed for 1D TiC nanostructure synthesis.…”

A simple method for synthesis of titanium carbide (TiC) nanofibers by a modified carbothermal reduction of electrospun titanium-based fibers is reported. The effect of synthesis steps on the final product is discussed. Continuous TiC fibers synthesized have a smooth surface morphology, with average diameter of 148 nm and length in the centimeter range. X-ray diffraction and high-resolution transmission electron microscopy analysis results indicate that the fibers consist of TiC of high purity. Impact of heat treatment on the morphology and chemical and crystalline composition of the product is also investigated. Based on the experimental evidence, it is hypothesized that the carbothermal reduction of calcined electrospun fibers with precoated carbon proceeds through diffusion-limited shrinking core pathway while that of the as-spun fibers follows the reaction-limited solution precipitation mechanism. The TiC nanofibers also show superior sintering properties by increasing theoretical density of hot pressed TiB 2 from 94.5% of theoretical density to 97.9% of theoretical density. When sintered with ceria, it improves the conductivity of the ceria by 18.29 times as compared to 2.94 times by TiC nanoparticles at 800°C. The TiC nanofibers show metallic behavior as well as potential for application as electrochemical double layer capacitor supercapacitors.

“…Similar TiC-C nanofibers structures made by the electrospinning method have been reported to more various applications. Zhou et al also utilized the electrospinning method to synthesize titanium carbide—carbon nanofibers (TiC/CNF) and found distinguished mechanical and electrical properties [54]. Also, such nanofibers (TiC/CNF) are promising to find their applications in titanium matrix composites (TMC), electronic devices as well as efficient catalyst scaffolds.…”

It is widely known that the special performances and extensive applications of the nanoscale materials are determined by their as-synthesized structures, especially their growth sizes and morphologies. Hereinto, titanium carbides, which show brilliant comprehensive properties, have attracted considerable attention from researchers. How to give full play to their potentials in the light-weight manufacture, microwave absorption, electromagnetic protection, energy conversion and catalyst areas has been widely studied. In this summarized article, the synthesis methods and mechanisms, corresponding growth morphologies of titanium carbides and their further applications were briefly reviewed and analyzed according to their different morphological dimensions, including one-dimensional nanostructures, two-dimensional nanosheets and three-dimensional nanoparticles. It is believed that through the investigation of the crystal structures, synthesis methods, growth mechanisms, and morphology characterizations of those titanium carbides, new lights could be shed on the regulation and control of the ceramic phase specific morphologies to meet with their excellent properties and applications. In addition, the corresponding development prospects and challenges of titanium carbides with various growth morphologies were also summarized.
