“…It is a flame retardant system that forms a porous expanded carbon layer during the heating process and promotes the flame retardant effect by insulating the heat and oxygen and preventing the volatilization of pyrolysis products [10]. Aside from the compact carbon layer, the type of carbon nanotubes (CNTs), carbon nanosheet and Polymers 2023, 15, 2135 2 of 14 carbon dots have also received much attention [11][12][13][14][15]. In the case of CNTs with high ratio of length to diameter, the continuous network structured protective layer forms a barrier that blocks the heat transfer and volatilization of combustible organics.…”

It is difficult to enhance the char yields of polypropylene (PP) due to the preferential complete combustion. Successful formation of abundant char layer structure of PP upon flammability was obtained due to the synergistic effect of NiO, Al2O3 and activated carbon (AC). From characterization of scanning electron microscopy (SEM) and transmission electron microscopy (TEM), it was revealed that the microstructure of residual char contained large amount of carbon nanotubes. Compared to the modification of AC, NiO and Al2O3 alone, the combination of AC, NiO and Al2O3 dramatically promotes the charring ability of PP. In the case of AC and NiO, NiO plays a role of dehydrogenation, resulting in the degradation product, while AC mainly acts as carbonization promoter. The addition of Al2O3 results in higher dispersion and smaller particle size of NiO, leading to greater exposure of active sites of NiO and higher dehydrogenation and carbonization activity. Compared to the neat PP, the decomposition temperature of the PP modified by combined AC, NiO and Al2O3 was increased by 90 ℃. The yield of residual char of AC-5Ni-Al-PP reached as high as 44.6%. From the cone calorimeter test, the heat release rate per unit area (HRR) and total heat release per unit area (THR) of PP composite follows the order AC-5Ni-Al-PP < AC-10Ni-Al-PP < AC-Ni-PP < AC-15Ni-Al-PP < AC-1Ni-Al-PP. Compared to the neat PP, the peak of HRR declined by 73.8%, 72.7%, 71.3%, 67.6% and 62.5%, respectively.

“…Although the introduction of a halogen- or phosphorus-based flame retardant is the common method of improving the flame retardancy of the materials, the limiting factor is the toxicity of the combustion products from a halogen-based flame retardants. A phosphorous-based flame retardant may be required in large amounts, which not only causes difficulties in the electrospinning process, but also affects the mechanical properties of the fibers [ 33 , 34 , 35 ]. Therefore, there is an urgent need for modifications to obtain flame retardant derivatives.…”

Reusing or recycling waste into new useful materials is essential for environmental protection. Herein, we used discarded polystyrene (PS) and fly-ash (FA) particles and a fabricated fly-ash incorporated polystyrene fiber (FA/PS fiber) composite. The electrospinning process produced continuous PS fibers with a good distribution of FA particles. The prepared nanofibers were characterized by state-of-the-art techniques. The performances of the composite nanofibers were tested for fire-retardant applications. We observed that the incorporation of FA particles into the PS fibers led to an improvement in the performance of the composite as compared to the pristine PS fibers. This study showed an important strategy in using waste materials to produce functional nanofibers through an economical procedure. We believe that the strategy presented in this paper can be extended to other waste materials for obtaining nanofiber membranes for various environmental applications.
