“…The present study has been added as additional evidence, by showing the potential SWNT‐mediated antimicrobial activity. With the evidences demonstrated, the current study serves as the model system for developing stable medicinally important components, can also be immobilized on the recent novel materials, and may create new opportunities …”

The primary purpose of this study was to determine the antimicrobial activity of functionalized single-walled carbon nanotube (SWNT) using an extract of the herb, Hempedu bumi. H bumi extract and H bumi extract complexed SWNT were evaluated for biological activities against Bacillus sp., (pathogen) Escherichia coli (opportunistic pathogen), and Aspergillus niger (pathogen).The formation of inhibition zones of these 3 microbes was measured to be evident for the functionalized SWNT with H bumi. Further, morphological and structural analyses were conducted to investigate the functionalized SWNT with H bumi using scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, X-ray powder diffraction, and Fourier transform infrared spectroscopy, well supporting the intact and crystalline nature of the SWNT. Fourier transform infrared spectroscopy result shows the highest peak at 3371.48 cm −1 , representing an andrographolide group from the plant extract. An apparent clear zone has been noticed with SWNT conjugated H bumi extract, displaying a zone of inhibition larger than 1.0 cm against the tested microbes. The results indicate that SWNT has the potential for use as a carrier of components from plant extracts.

“…Nanotechnology ("nanotech") deals the manipulation on an atom and molecular scale. It was subsequently reached a clear level with one dimension size ranged from 1 to 100 nanometers [5][6][7][8][9]. Nanotechnology and Nanoscience deal the ability to observe and to control the individual atom and molecule.…”

Nanocellulose prepared from the natural material has a promising wide range of opportunities to obtain the superior material properties towards various end-products. In this research, commercially available natural cotton was treated with aqueous sodium hydroxide solution to eliminate the hemicellulose and lignin, then cellulose was collected. The collected cellulose was subjected to acid hydrolysis using sulfuric acid to obtain nanocellulose. The prepared nanocellulose was further characterized with the aid of Fourier transform infrared spectroscopy, X-ray diffraction and Scanning Electron Microscopy to elucidate the chemical structure, crystallinity and the morphology.

“…Due to its remarkable properties, graphene has found applications in most fields: electronics, [101] batteries and supercapacitors, [102] construction materials, [103] food packaging, [104] and biomedical applications. [105] The biggest challenge of graphene incorporation in polymer mixtures is the exfoliation. Due to Van der Waals forces, graphene layers tend to stack together forming a graphitic structure and no significant improvement in the final properties of the composite is observed.…”

The synthesis of composite materials based on various carbon structures and polybenzoxazines (PBZs) gives products with noticeable thermal, electrical, and mechanical properties. The role of different carbon materials is emphasized in terms of the main advantages in both structure and properties. On the other hand, the PBZ features are significant considering the high glass transition temperatures, low flammability, high char yields, and good thermal stability. This review article describes the synthesis, structure, and properties of polybenzoxazine composites based on carbon fibers, carbon nanotubes, graphene, graphene oxide, and other carbonaceous materials. Particular attention is given to the interactions possible to occur between the polybenzoxazine matrix and carbon component.
