“…Cellulose was isolated from corncob powder through a bleaching process using 1.7% (v/v) NaOCl at 80°C for 5 h and delignification with 2 M NaOH at 80°C for 4 h. CNC is produced from isolated cellulose by hydrolysis using 50% (v/v) H 2 SO 4 at 45°C for 60 min as described in previous research 38 …”

In the field of high‐energy‐density lithium‐ion battery applications, Polymer electrolyte membranes (PEMs) have garnered significant attention due to their favorable mechanical properties and compatibility with lithium metal anodes. However, their relatively lower ionic conductivity compared to liquid electrolytes, making this problem a challenge for further research. In this study, we present a new approach to overcome these limitations, resulting in PEMs that exhibit exceptional ionic conductivity, flexibility, and interface stability. This achievement was realized by blending polyvinyl alcohol (PVA)/LiClO4 composite reinforced cellulose nanocrystalline (CNC), which is sourced from well and carefully isolated corncob cellulose. PEMs show remarkable improvements regarding ionic conductivity and mechanical strength. Membrane transparency decreased with increasing CNC addition. The maximum improvement mechanical strength was observed with the addition of 5% CNC, namely elongation at break (strain) increased by 15%. At the same composition shows an increase in ionic conductivity to 1.31 × 10−4 S/cm. This study provides the potential of precise material design and composition optimization in overcoming drawbacks associated with conventional PEMs. The findings not only advance the current understanding but also provide a promising avenue for the development of high‐performance PEMs, which are critical for the evolution of future energy storage technologies.

“…Hydrogen peroxide was used in delignification process. Cellulose hydrolysis reaction following the procedure described by Purwanti et al (2015) [13]. The isolated cellulose was reacted with sulfuric acid with various concentrations and hydrolysis time at a ratio of 1:25 (w/v) at 45 o C. After several sets of hydrolysis attempt, we found two optimized condition.…”

Wettability is one factor that influences the enhanced oil recovery. Water-wet surfaces are predicted increasing the oil recovery from the reservoir. Microcellulose has the potential to produce water-wet surfaces. In this experiment, two types of microcellulose were used with different particle sizes of 2.9 μm and 14 μm. Both types of microcellulose are then applied to the reservoir rock surface model, i.e the surface of bentonite which has been soaked in crude oil for one week at 60 °C. Contact angle measurement shows that there is a decrease in water-the reservoir rock surface model contact angle from ~ 90 ° to ~ 80 ° when applied microcellulose solution 0.5% w/w. The difference in microcellulose size causes a difference in contact angle of about 5° at microcellulose solution 2.5%. This shows the application of microcellulose on the reservoir rock surface model causing the surface to be more water-wet.

“…3c), and the width of the characteristic bands also increases, which is due to the formation of more hydrogen-bonds between cellulose fibers and cellulose pulp after regeneration. 40,41 In the FTIR spectrum of the CF-0.6Z membrane, the bands at 429 cm À1 and 1586 cm À1 correspond to the stretching vibration of Co-N and CQN in the ZIF-67 crystals, respectively. 42,43 However, the stretching vibration band of -OH in the CF-0.6Z membrane shifts from 3288 cm À1 to 3308 cm À1 , which is attributed to the disruption of hydrogen-bond formation between the regenerated cellulose molecules during the synthesis of ZIF-67 particles.…”
