“…The diameter of the fibers prepared by the electrospinning process generally increases with the increase in the solid content of the solution. , When the solid content of PS is changed in the spinning solution, PSN fibers with different diameters could be obtained (Figure ). The diameter of the fiber increases with the increase in the PS content in the solution.…”

The adsorption capacity of a solid amine adsorbent for CO 2 adsorption is often limited by the number of amino groups on the adsorbent surface. In this paper, a kind of ultrafine solid amine fiber (PSN) was prepared by direct electrospinning of polyethylenimine blends, which could provide plentiful amino groups on the fiber surface without further modification and would improve the CO 2 adsorption capacity and amino utilization efficiency of the fibrous adsorbent. The effects of the adsorbent structure on the CO 2 adsorption performance of PSN was investigated. The results indicated that the fibrous structure and higher outer surface area of PSN can greatly improve its adsorption capacity and adsorption rate for CO 2 . Under the simulated flue gas conditions (90% N 2 /10% CO 2 ) at 25 °C, the CO 2 adsorption capacity of PSN fiber is 2.10 mmol/g, and its CO 2 adsorption capacity could reach 4.98 mmol/g at 75 °C. The diameter of the fiber obviously affects the CO 2 adsorption behavior of the solid amine adsorbents; an increase of the fiber diameter would result in the decrease of the adsorption capacity of the adsorbents. PSN has good regeneration stability, and its CO 2 adsorption performance remained almost unchanged after a number of regeneration cycles.

“…Tong et al employed a hot-injection method to synthesize lead halide PNCs incorporated into acrylic monomers, producing nanocrystal-polymer composite films characterized by remarkable stability and brightness [ 22 ]. Zhang et al incorporated CsPbBr 3 PNCs into PS polymer nanofiber employing a one-step electrospinning process and demonstrated its effectiveness in enabling the high-efficiency detection of fluorescence in rhodamine solutions [ 23 ]. Babu et al synthesized highly stable CsPbBr 3 incorporated poly (vinylidene fluoride)-co-hexafluoropropylene fibers employing electrospinning technique and studied the charge-transfer dynamics employing transient absorption (TA) spectroscopy.…”

“…Due to the higher resistance to the environment, the polymer cladding material can effectively passivate the surface defects and modulate the optoelectronic properties of nanocrystals, while also significantly improving their stability in water and under oxygenated conditions. The outer layer protection can also greatly reduce the hydrolysis and agglomeration of the nanocrystals [ 31 ].…”

Abstract3D CsPbX3 inorganic perovskite materials have attracted much attention in optoelectronic devices because of their strong absorbance, high photoluminescent quantum yield, tunable band gap, and narrow emission bandwidth. However, their practical usefulness is limited due to their poor stability in ambient conditions. Here, we created photoluminescent 0D Cs4PbX6 (X = Br, Br/I) suspensions in toluene by adding a small amount of water. The photoluminescent 0D Cs4PbX6 perovskite was mixed with polymethylmethacrylate (PMMA) forming 0D Cs4PbX6/PMMA composite films with higher PL, stability, transparency, and transmittance than that of the 3D CsPbX3/PMMA composite films prepared separately. Moreover, the PL intensity maintains 90% of the initial value after 30 days in water, showing excellent water stability. The flexible white-light LED device prepared by the composite films illustrated good luminescence performance with color rendering index 74.77, chromaticity coordinates (0.32, 0.33), and color temperature 6997 K.
