“…The bers may be changed in chemical or physical treatments [12,14]. 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.…”

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.

“…The fibre properties will initially improve with increasing permanganate concentration before abruptly deteriorating once a particular threshold is achieved, suggesting the degradation of cellulosic fibres that will result in polar groups between the fibres and the matrix. As such, the fibre qualities depend strongly on the treatment's concentration and the duration of exposure 45 , 47 , 50 , 52 , 62 . According to some studies, treating natural fibre with KMnO 4 can significantly lessen the amount of water that it can absorb.…”

Humans are the only species who generate waste materials that cannot be broken down by natural processes. The ideal solution to this waste problem would be to employ only compostable materials. Biodegradable materials play a key role in creating a safer and greener world. Biodegradability is the gift that keeps on giving, in the sense of creating an Earth worth living. The future is thus best served by green energy, sustainability, and renewable resources. To realize such goals, waste should be considered as a valuable resource. In this context, Zea mays (Zm) root fibres, which are normally considered as agricultural waste, can be used as reinforcing substances in polymer matrices to produce structural composite materials. Before being used in composites, such fibres must be analysed for their physical properties. Chemical treatments can be employed to improve the structural quality of fibres, and the changes due to such modification can be analysed. Therefore, the current work examines the effect of permanganate treatment on the surface properties of Zm fibres. The raw and potassium permanganate-treated samples were assayed for various properties. Physical analysis of the fibre samples yielded details concerning the physical aspects of the fibres. The thermal conductivity and moisture absorption behaviour of the samples were analysed. Chemical analysis was employed to characterize the composition of both treated and untreated samples. p-XRD was employed to examine the crystalline nature of the Zm fibres. Numerous functional groups present in each sample were analysed by FTIR. Thermogravimetric analysis was used to determine the thermal stability of Zm fibres. Elemental analysis (CHNS and EDS) was used to determine the elemental concentrations of both raw and treated samples. The surface alterations of Zm fibres brought on by treatment were described using SEM analysis. The characteristics of Zm roots and the changes in quality due to treatment were reviewed, and there were noticeable effects due to the treatment. Both samples would have applications in various fields, and each could be used as a potential reinforcing material in the production of efficient bio-composites.

“…Soaking with potassium permanganate may increase the roughness of the natural fiber. In addition, drinking with potassium permanganate increases the degree of surface interlock in removing a substance known as cellulose while decreasing the hydrophilic properties in natural fiber [10]. Then, the composition of some natural fibers is presented in Table 2.…”

<p>Natural fibers, with environmental, economic, and cost advantages, are highly sought-after for biocomposite materials. In the present study, the biocomposite samples of epoxy resin (as a matrix), bagasse fiber (as reinforcement), and rice bran (as a filler) were prepared. Tensile strength, strain, and Young's modulus will be the parameters concerning which the quality of the biocomposite can be tested. On the one hand, bagasse fiber is to be a strength enhancer in the resulting biocomposite. On the other hand, rice bran may increase the biocomposite's density. The process research comprises fiber yarn from milled bagasse, alkalized fiber with KMnO4, specimen printing process, and analysis. All the fibers were treated by soaking them in 3 grams of KMnO4 solution for 30 and 45 minutes. The fiber is drained in an oven at 50 °C for ±1.5 hours. The printed fiber onto a specimen mold was printed with a mixture of epoxy resin and rice bran (1:1 w/w) and left for one day. Variation in the fiber mass was at 3, 4, and 5 grams. The sizes of the specimens were similar to the size of the mold according to ASTM D-638 type IV. Then, the fibers were removed from the mold and tested for tensile strength, strain, and Young's modulus. The results show that the greater the fiber mass, the greater the tensile strength value. These findings indicate that the tensile strength was optimized after soaking for 45 minutes with 5-gram fiber weight, which resulted in the tensile strength of 26.32±0.25 MPa, strain of 9.65±0.14%, Young's Modulus of 3.29±0.05 MPa, and water absorption of 41.99%.</p>
