“…According to Ghaee et al, 39 adding 3% hydrophilic surface modifying macromolecules to PCL can also reduce contact angles to almost zero. Such changes in wettability have already been achieved by modifying NF by plasma or blending it with hydrophilic polymers like chitosan 40,41 . As per our study, no one has yet modified PCL by surfactant addition.…”

Electrospinning of polycaprolactone (PCL) nanofiber (NF) was carried out with bis (2-ethylhexyl) sulfosuccinate (AOT) and Triton X 100 (TX 100) surfactants. PCL and surfactant concentration were optimized to get fine NF. The morphological study of the NF was carried out by scanning electron microscope and atomic force microscopy. The structural changes were evaluated by X-ray diffraction, and its elemental mapping was analyzed by energy dispersive X-ray mapping. The addition of surfactants altered the morphology of PCL NFs and improved their physiochemical properties, such as wettability, roughness and crystallinity. Among these two surfactants, AOT gave a better NF structure. In the presence of AOT, the hydroalcoholic extract of Terminalia arjuna (TA) was incorporated as the herbal drug, and antibacterial behavior against gram-positive and gram-negative bacteria was monitored. The novelty of this work was in the use of a surfactant as a cospinning agent for dual purposes in a single step. The surfactant changed the hydrophobic PCL into a superhydrophilic matrix and incorporated herbal extract to develop an infection-resistance nanofiber. The developed PCL/TA nanofiber showed excellent potential as an antimicrobial agent with antioxidant properties.

“…[10,11] Among all kinds of transition metal-based pseudocapacitive materials, layered double hydroxides (LDHs) have attracted special attention due to their 2D layered structure, abundant redox reaction sites, and tunable composition. [12,13] To enhance the electrochemical potential of LDH based electrodes for SCs, tremendous efforts have been devoted, such as coupling with conductive carbonaceous materials (graphene and carbon nanotubes), [14,15] defect engineering, [16,17] introducing heteroatoms, [15,18] forming the core-shell structure of LDH, [19,20] and integrating the LDH nanosheets to form an array on a conductive substrate (Ni-Foam/carbon cloth). [17,18] Another effective approach to improve the electrochemical performance of LDHs is incorporating high-conductive polymers.…”

Creating nanosized pores in layered materials can increase the abundant active surface area and boost potential applications of energy storage devices. Herein, a unique synthetic strategy based on polyaniline (PANI) doped 2D cobalt-iron layered double hydroxide (CoFe-LDH/P) nanomaterials are designed, and the formation of pores at low temperature (80 °C) is developed. It is found that the optimized concentration of PANI creates the nanopores on the CoFe-LDH nanosheets among all other polymers. The well-ordered pores of CoFe-LDH/P allow the high accessibility of the redox-active sites and promote effective ion diffusion. The optimized CoFe-LDH/P2 cathode reveals a specific capacitance 1686 (1096 Cg −1 ) and 1200 Fg −1 (720 Cg −1 ) at 1 and 30 Ag −1 respectively, a high rate capability (71.2%), and a long cycle life (98% over 10 000 cycles) for supercapacitor applications. Charge storage analysis suggests that the CoFe-LDH/P2 electrode displays a capacitive-type storage mechanism (69% capacitive at 1 mV s −1 ). Moreover, an asymmetric aqueous supercapacitor (CoFe-LDH/P2//AC) is fabricated, delivering excellent energy density (75.9 Wh kg −1 at 1124 W kg −1 ) with outstanding stability (97.5%) over 10 000 cycles. This work opens a new avenue for designing porous 2D materials at low temperature for aqueous energy storage devices.

“…Chen et al and Huang et al designed and prepared branched and star-shaped PSA with improved processing and thermal properties using zinc powder catalysis. [24,25] Subsequently, Huang et al investigated the mechanism of zinc-promoted silylation by combining experimental and computational research. [26] The zinc powder catalysis method offers several distinct advantages over the Grignard reagent method, which requires the use of a stoichiometric amount of organometallic reagents and complex reaction processes.…”

A novel one-step synthesis of silicon-containing arylacetylene resin (PSA) catalyzed by Et 2 Zn was reported. PSA-Et 2 Zn was prepared by the reaction between diethynylbenzene and dichlorodimethylsilane in the presence of diethylzinc. The structure of PSA-Et 2 Zn was determined and the reaction mechanism was proposed. In addition, the processability, thermal curing behavior, and thermal properties were studied. When compared with the zinc powder catalysis method, the Et 2 Zn catalysis method demonstrates a greater effectiveness in avoiding the formation of olefinic products at the ends of the molecular chain, which can improve thermal capabilities. The results show that PSA-Et 2 Zn possesses excellent processability and thermal properties. PSA-Et 2 Zn has a wide processing window of 35 ∼ 182 °C and the thermal crosslinking reactions of PSA-Et 2 Zn resin are mild. The cured PSA-Et 2 Zn shows high thermal stability with a residue yield up to 87.9 % at 800 °C. Furthermore, the temperature at 5 % weight loss in nitrogen and air atmospheres is 584 °C and 539 °C, respectively.
