This report describes the manufacture of polyethyleneimine husk char/activated carbon nanofiber composites by electrospinning and physical activation techniques, as well as its adsorption results toward CO2 based on CO2 based on a graph. The finished ACNF composite with 1% of GRHC has a smaller average fiber diameter, a narrow surface area of 597 cm 2 /g, and a V micro of 0. 2606 cm 3 /g, which is superior to pristine ACNFs. At atmospheric pressure and 25° C, 142 cm 3 /g at atmospheric pressure and 25'u00b0C, substantially higher than that of pristine ACNF/GRHC0. 01, significantly higher than that of pristine ACNF/GRHC 0. 01's 69 cm 3 /g. Notably, the adsorption results of CO 2 are directly proportional to the pressure rise, but it is also proportional to the rise in temperature. Interestingly, both amine-impregnated and nonimpregnated GRHC/ACNFs used the pseudo first-order kinetic model at 1 bar, but the pseudo first-order kinetic model at 15 bars was the most effective; however, the pseudo second-order kinetic model was the best fitted the pseudo second-order kinetic model at 15 bars.

In this report, we design, produce, and display characterizations of a stretchable interdigitated capacitive strain gauge based on carbon nanofiber/polyaniline/silicone rubber nanocomposite, which leads to a decrease in sensitivity with linearity, as well as low hysteresis. Although low sensitivity is one of capacitive strain gauges' challenges, we found an increase in sensitivity with linearity and low hysteres Even under heavy strain, the strain sensor's sensitivity is heightened not only by the interdigitated electrode design but also by the electrodes' outstanding electrical conductivity.
