“…The thermal properties of the final fibers were evaluated by TGA analysis, which is the generally accepted method indicating the decomposition/degradation steps of polymeric materials ( Figure 8 ). As is known from the literature, the initial thermal decomposition of halogenated polymers usually starts with the dehydrochlorination process and finally ends with the respective chain scission [ 39 ]. In our case, the first thermal decomposition of PP-Cl microfibers initiated at 195 °C and the second step was observed at 415 °C owing to the dehydrochlorination and degradation of the unchlorinated PP backbone, respectively.…”

A novel amphiphilic graft copolymer possessing polypropylene (PP) main chain and poly(oligoethylene glycol methacrylate) (POEGMA) pendant units was synthesized starting from chlorinated polypropylene (PP-Cl), and characterized. PP-Cl produced macroradicals at chlorine bounded carbon atoms by visible light irradiation in the presence of dimanganese decacarbonyl [Mn 2 (CO) 10 ] and initiated the free-radical photopolymerization of an acrylate monomer, namely oligoethylene glycol methacrylate (OEGMA). Furthermore, fiber formation ability of PP- g -POEGMA was tested by electrospinning technique. The chemical structure and some features of the corresponding amphiphilic graft copolymer PP- g -POEGMA was characterized by implementing spectral (FT-IR, 1 H-NMR), chromatographic (GPC), morphological (SEM), water wettability (WCA), and thermal (TGA) analyses. It was clear from the SEM results that the average diameter of the obtained microfibers decreased with the incorporation of POEGMA segments onto the PP-Cl main chain. Based on WCA measurements, PP- g -POEGMA was determined as more wettable than PP-Cl due to its hydrophilic POEGMA building blocks. This facile procedure could be utilized to achieve the amphiphilic commercial polymers for potential bioapplications such as drug delivery.

“…When used as a supercapacitor, its maximum specific capacitance is 50 F g −1 , and the capacity retention rate is 100% after the 2000th cycle; the maximum reversible capacitance when used as a LIB has also been improved. Altinkok et al [ 19 ] used electrospinning process to prepare composite nanofibers using phosphorylated polyvinyl chloride and polyethyleneimine as raw materials. The nanofibers can be used in the biological field.…”

As an important inorganic material, alumina ceramic nanofibers have attracted more and more attention because of their excellent thermal stability, high melting point, low thermal conductivity, and good chemical stability. In this paper, the preparation conditions for alumina spinning gel, such as the experimental raw materials, spin finish aid, aging time, and so on, are briefly introduced. Then, various methods for preparing the alumina ceramic nanofibers are described, such as electrospinning, solution blow spinning, centrifugal spinning, and some other preparation processes. In addition, the application of alumina ceramic nanofibers in thermal insulation, high-temperature filtration, catalysis, energy storage, water restoration, sound absorption, bioengineering, and other fields are described. The wide application prospect of alumina ceramic nanofibers highlights its potential as an advanced functional material with various applications. This paper aims to provide readers with valuable insights into the design of alumina ceramic nanofibers and to explore their potential applications, contributing to the advancement of various technologies in the fields of energy, environment, and materials science.

“…[15,16] Fibers based on polymeric (natural or synthetic) or inorganic (metals, ceramics, and glasses) materials can be obtained by a number of techniques, including phase separation, interface polymerization, electrochemical assembly, and particularly spinning techniques. [17,18] Electrospinning is the most common ber-forming technique used to produce continuous bers with diameters ranging from polymer melts or solutions, typically tens of nanometers to several micrometers, via an electrostatic eld. [19] While electrospinning studies on polymers with a wide variety of functionalities are available in the literature, but PP has the disadvantage of insoluble in polar solvents at room temperature, making it di cult to implement the electrospinning process.…”
