“…Bamboo contains large amounts of cellulose, hemicellulose, and lignin; thus, it can function as a polymeric filler with an ideal strengthening effect. Moreover, its low density, low cost, high biodegradability, and nontoxicity increase its application potential. , Composites comprising natural vegetable fibers and bio-based polymers have been shown to exhibit poor interface compatibility, which influences the composite performance; thus, modifications of constituent raw materials are necessary. The PLA- g -MAH was maleic anhydride (MA)-grafted PLA and used as an interfacial compatibilizer.…”

The development of green and renewable materials has attracted increasing attention in recent years. Hence, biocomposite-based packaging materials have been investigated to replace petrochemical materials in several industries, such as the food packaging and electronics packaging industries. The tensile and thermal properties of biocomposite-based packaging materials composed of polylactic acid and plant fiber were mainly investigated in the current literature, but fewer studies on the improvement of water resistance and water vapor/oxygen barrier properties of composite materials were performed. Herein, we describe a composite film comprising TBFP [a mixture of bamboo fiber powder (BFP) and silica aerogel powder] that was combined with modified polylactic acid (MPLA) in a melt-mixing process. The structure, morphology, tensile strength, thermal properties, water absorption properties, water vapor/oxygen barrier effect, cytocompatibility, and biodegradability of the composites were characterized. MPLA and TBFP improved the properties of these composites. Fourier transform infrared and X-ray diffraction spectra have shown interfacial adhesion of MPLA/TBFP, resulting in a tighter structure. Hence, the MPLA/TBFP composite had higher elongation at failure (ε), tensile strength at failure (δ), Young’s modulus (E), initial decomposition temperature at 5 wt % loss (T 5%), residual yields, oxygen transmission rate, contact angles, lower thermal conductivity (k) values, water vapor transmission rate, and water absorption and biodegradability compared with PLA and PLA/BFP. It indicates that the MPLA/TBFP composites exhibited more favorable tensile strength, water resistance, and water vapor/oxygen barrier than the PLA and PLA/BFP composites. Cell growth analysis showed that the MPLA/TBFP and PLA/BFP composites own good cytocompatibility. Moreover, the biodegradability of the PLA/BFP and MPLA/TBFP composites increased with the filler (BFP or TBFP) concentration. Because of these improvements in their properties, composites can be used as packing materials in many perspectives.

“…As the temperature increased to 1000 °C, PKS-PAC and ). An increase in activation temperature to 1000 °C leads to the higher carbon breakdown, resulting in the formation of new particles and the enlargement of existing pores (Farma et al 2021). Chin et al (2015) reported that the ash in oil palm biomass was completely melted when exposed to 900 °C, which resulted in molten ash.…”

Granular activated carbon (GAC) and powdered activated carbon (PAC) are the two most common forms of activated carbon with varying particle size range. The goal of this study was to analyze the key factors (particle size and activation temperature) affecting the surface characteristics of GAC and PAC derived from palm kernel shell (PKS). The surface morphology suggested that the pore network in PKS-PAC is more developed than that in PKS-GAC owing to the presence of a micropore structure when prepared at lower activation temperatures. This study also demonstrated that activation performed on different PKS particle size range influenced the mesopore domain of the activated carbon produced. The PKS-GAC was found to have more mesopores than PKS-PAC, which made it more reliable for dye adsorption in water treatment. Overall, this study demonstrated that applying different particle size range of PKS during the activation process can have a significant influence on the surface characteristics, thus having a direct impact on the application of activated carbon. An accurate particle size range will ensure that the most cost-effective activated carbon is selected to achieve the desired performance objectives.

“…Physical activation is slightly more desirable as it is safer and provides activated carbon with better control over porosity. Physical activation is a process with two-steps: the first step is carbonisation under inert conditions, followed by activation through the introduction of an activation agent [60]. In the case of physical activation, air, steam, carbon dioxide, or a mixture of these is utilised as the activation agent.…”

Carbon-Based Materials for Supercapacitors: Recent Progress, Challenges and Barriers

Swift developments in electronic devices and future transportation/energy production directions have forced researchers to develop new and contemporary devices with higher power capacities, extended cycle lives, and superior energy densities. Supercapacitors are promising devices with excellent power densities and exceptionally long cycle lives. However, commercially available supercapacitors, which commonly use high-surface-area carbon-based electrodes and organic solutions as electrolytes, suffer from inferior energy densities due to the limited accessibility of surface area and constrained operating potential window of electrolytes. To address the issue of inferior energy densities, new high-capacity electrode materials and new/state-of-the-art electrolytes, such as ionic liquids, gel polymers, or even solid-state electrolytes, have been developed and evaluated vigorously in recent years. In this brief review, different types of supercapacitors, according to their charge storage mechanisms, have been discussed in detail. Since carbon-based active materials are the key focus of this review, synthesis parameters, such as carbonisation, activation, and functionalisation, which can impact a material’s physiochemical characteristics, ultimately affecting the performance of supercapacitors, are also discussed. Finally, the synthesis and applications of different carbon-based materials, i.e., carbon nanotubes, graphene, and activated carbon, have been reviewed, followed by conclusions and outlook.
