“…Also, natural bers treated with mercerization, silane treatment, benzoylation, potassium permanganate, etc., have signi cant advantages, such as lower water absorption, increased surface roughness, and higher thermal stability, less amorphous content, improved crystallinity index, and increased crystallite size [15][16][17]. Natural bers are obtained from various plants such as tree bark such as Azadirachta indica, Ceiba pentandra, Acacia Concinna, Grewia tilifolia, Acacia Nilatica L., Acacia leucophloea, ramie, and yarn have been a focus of research for scientists as reinforcements of composite because of their speci c properties and availability [18][19][20][21][22] The future research will investigate a new bark fabric Dittrichia viscose L (Inula Viscosa) plant that has not been studied so far, despite its abundance in the Mediterranean region, Southeast Europe, and Asia West. In this study, two different chemical treatments, 3% alkaline and 3% permanganate, were adopted to modify the IV bers samples of bark were harvested using an ecological technique.…”

This research aims to analyze the newly discovered cellulosic ber from the bark of Dittrichia viscosa, or Inula viscosa (IV), and evaluate the effects of permanganate and alkali chemical treatments on the physical properties to improve the interfacial bonding between Inula viscosa reinforced polymer composites. These permanganate and alkali treatments are both e cacious in helping in reducing hydrophilicity and eliminating impurities from the ber surface, which has been con rmed by scanning electron microscope (SEM) observation, thermogravimetric analysis (TGA), X-ray diffraction (XRD), and Fourier Transform Infrared Spectrometry (FTIR). Permanganate-treated IVFs have shown higher tensile strength and interfacial stress resistance (IFFS) than alkaline IVFs, and untreated IVFs by tensile and droplet tests. The different characteristics were studied and compared with other bark bers already available. It is estimated that the ber treatments will enable high-quality IVF-reinforced polymer composites for use in the industry.

A recently discovered Egyptian wooden statue of King Djedefre was studied together with some surrounding burial soil samples for assessing the statue biodeterioration. The wooden morphological characterisation identified the hardwood Acacia nilotica as the wood type. X-ray diffraction, micro-FT-IR spectroscopy, and scanning electron microscopy with an X-ray spectrometer were used to evaluate the wood deterioration degree and the soil contribution in wood biodeterioration. Microbiological analyses (fluorescent in situ hybridisation and polymerase chain reaction) were also performed to detect the microbial attack on the statue. The prolonged interaction of the statue with the burial environment caused a strong wood decay due to biotic (fungi and bacteria) and abiotic factors (e.g., humidity fluctuations of the burial environment), which caused the severe cracking and collapsing of the wood structures. The analyses of the burial soil mineral composition were relevant for obtaining an overall picture of the statue deterioration. The results are useful for planning the right conservation procedures for this very particular and important wooden statue. Furthermore, analysis of the woody cell wall will help in the selection of appropriate consolidation and recovery treatments. Because the statue is a unique single piece of wood, and the morphological observations indicated that it is a bald woman in a sitting position, this statue will provide new and interesting knowledge of Egyptian culture.

Application of natural fiber-polymer composites (NFPCs) in different industrial applications provides competitive edge due to their lightweight, higher specific mechanical properties than glass fibers, sustainability, and lower cost involved in production. There are certain challenges associated with natural fibers and their reinforcement in composites such as poor bonding between the fibers and matrix due to their contradictory nature of characteristics, moisture absorption, lower thermal properties, and poor interfacial adhesion between the natural fiber and polymer matrix. The challenges involved in NFPCs need to be overcome to produce materials with relatively equivalent properties to those of conventional composites and other metallic structures. Several researchers around the globe have conducted investigations with the primary attention being paid to the modification of natural fibers and matrix by employing surface treatments and other chemical treatment methods. In order to address the need for eco-friendly and sustainable materials in different domains, a comprehensive review on natural fibers and their sources, available matrix materials, modification techniques, mechanical and thermal properties of NFPCs, is needed for better understanding of the behavior of NFPCs. This work provides the information and holistic view of natural fiber-reinforced composites based on the results obtained from modification techniques, with the view of focusing the review in terms of different chemical and physical treatment techniques, modification of fibers and matrix, and enhanced mechanical and thermal properties in the composites.
