“…Third, during acid washing with HCl solution and subsequent rinsing with distilled water, the removal of metallic solid substances that act as hard templates may aid in the formation of interconnected porous structures. 39 WSC–PH also featured a porous structure, and its pore-formation mechanism was similar to that of the previously mentioned carbonate (K 2 CO 3 ). During the reaction, KOH is converted into K 2 CO 3 , K 2 O, and CO ( eqn (13)–(15) ).…”

“…They demonstrate resistance to acidic environments but are susceptible to alkaline conditions [ 15 ]. Their versatile use includes applications in oil sorption [ 16 ], supercapacitors [ 17 ], and high-capacity anode material [ 18 ], and they are safe for direct human contact due to a pH of 6.7 [ 15 ]. Similarly, kapok fibers, known for their thin cell wall and large lumen, have traditionally been used as stuffing material in items like pillows and life jackets [ 14 , 19 ].…”

Disposable surgical gowns are usually made from petroleum-based synthetic fibers that do not naturally decompose, impacting the environment. A promising approach to diminish the environmental impact of disposable gowns involves utilizing natural fibers and/or bio-based synthetic fibers. In this study, composite webs from polylactic acid (PLA) bicomponent fiber and natural fibers, cattail and kapok fibers, were prepared using the hot press method. Only the sheath region of the PLA bicomponent fiber melted, acting as an adhesive that enhanced the strength and reduced the thickness of the composite web compared with its state before hot pressing. The mechanical and physical properties of these composite webs were evaluated. Composite webs created from kapok fibers displayed a creamy yellowish-white color, while those made from cattail fibers showed a light yellowish-brown color. Additionally, the addition of natural fibers endowed the composite webs with hydrophobic properties. The maximum natural fiber content, at a ratio of 30:70 (natural fiber to PLA fiber), can be incorporated while maintaining proper water vapor permeability and mechanical properties. This nonwoven material presents an alternative with the potential to replace petroleum-based surgical gowns.

“…The best electrochemical properties were confirmed at 800 °C with a specific capacitance of 318 F g -1 at a constant current density of 0.5 A g -1 . In addition, Song et al (2020) and Liu et al (2020) used a similar method to obtained porous activated carbon from cattail fiber and lotus leaves for supercapacitor applications [21,22]. However, all of the above reports prepared electrode materials from porous activated carbon in powder/granular form post-synthesis binders for evaluation of their electrochemical properties.…”

Monolith solid porous carbon approach was prepared from biomass based from Garcinia Xanthochymus by using a high-temperature pyrolysis both of carbonization and physical activation in one stage integrated stage. Effect of the chemical impregnated of the activated carbon was studied. The N2 gas environment was used as inert gas of carbonization, and the CO2 gas was used as a physical activation atmosphere. The dimension of solid coin porous carbon was evaluated in the before and after high-temperature pyrolysis based on reduction of mass, diameter, and thickness. Furthermore, the porous carbon obtained also reviewed microstructure properties by using X-ray diffraction technique. Moreover, the electrode materials were evaluated their electrochemical performances at cyclic voltammetry (CV) and galvanostatic charge discharge (GCD) in different scanning rate of 1, 2, 5, and 10 mV s−1, at window voltage of 0.0-1.0V and current density of 1.0 A g−1. The optimum capacitive properties were found as high as 159 F g−1 at aqueous electrolyte of 1 M H2SO4. The energy density was reviewed of 9.91 Wh kg−1 at optimum power density of 97.17 W kg−1.
