“…Stretching vibration of fingerprint at 2916.57 cm −1 illustrated the presence of C-H alkyl groups in the cellulose backbone [ 35 ]. With the heat-treated EFB, the vibration peaks at 2362.45 cm −1 weakened, thus concluding that the amounts of hydroxyl, hemicellulose, and cellulose were reduced when the EFB were exposed to the heat treatment [ 36 ]. The C=C stretching of the aromatic ring of lignin in untreated EFB at 1425.13 cm −1 was reduced to 1372.36 cm −1 after heat treatment, indicating the loss of lignin [ 37 ].…”

Oil pollution such as diesel poses a significant threat to the environment. Due to this, there is increasing interest in using natural materials mainly from agricultural waste as organic oil spill sorbents. Oil palm’s empty fruit bunch (EFB), a cost-effective material, non-toxic, renewable resource, and abundantly available in Malaysia, contains cellulosic materials that have been proven to show a good result in pollution treatment. This study evaluated the optimum screening part of EFB that efficiently absorbs oil and the physicochemical characterisation of untreated and treated EFB fibre using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). The treatment conditions were optimised using one-factor-at-a-time (OFAT), which identified optimal treatment conditions of 170 °C, 20 min, 0.1 g/cm3, and 10% diesel, resulting in 23 mL of oil absorbed. The predicted model was highly significant in statistical Response Surface Methodology (RSM) and confirmed that all the parameters (temperature, time, packing density, and diesel concentration) significantly influenced the oil absorbed. The predicted values in RSM were 175 °C, 22.5 min, 0.095 g/cm3, and 10%, which resulted in 24 mL of oil absorbed. Using the experimental values generated by RSM, 175 °C, 22.5 min, 0.095 g/cm3, and 10%, the highest oil absorption achieved was 24.33 mL. This study provides further evidence, as the data suggested that RSM provided a better approach to obtain a high efficiency of oil absorbed.

“…These results were confirmed by some authors [36][37][38] who reported that the band at 1653 cm -1 indicated the oxidation of cellulose. Hao et al [39] stated that the thermal ageing has affected the chemical stability of cellulose bands. Garside and Wyeth [40] identified the cellulose bands of cotton and flax fibers.…”

As known, linen and muslin cotton fibers are used in museums and excavation areas as packaging materials for first aid of mummies. These materials with the course of long-term exposure to improper surrounding conditions become brittle, fragile, and very weak. The current research study aimed to evaluate the effect of guar gum with different concentrations for the consolidation of linen and muslin cotton samples. Additionally, the work aimed also to monitor the changes in the properties of these materials after accelerated heat aging at 100℃. The analytical techniques used for this purpose were Fourier Transform Infrared spectroscopy (FTIR) for examining the chemical changes, the morphological structure via using scanning electron microscope (SEM), mechanical properties (tensile strength and elongation), color and weight change for the treated linen and muslin cotton fabrics. The findings of FTIR proved that there were low chemical changes in the aged treated samples compared to the aged untreated samples implying that the chemical stability of the treated samples was increased while treatment with guar gum. There was good distribution in the fiber structure of the treated samples as shown from SEM data. The aged treated samples showed less destruction in the fiber structure compared to the aged untreated samples. The mechanical properties were also improved. The total color differences obtained from treated and aged treated muslin cotton samples were better than the linen samples. Moreover, the accelerated heat aging had an effect on the weight of the aged treated samples, which were better than the aged untreated samples.

“…It was possible that the active groups on small molecules were also increasing. Absorbance peaks at 1057 cm −1 , 1420 cm −1 , and 1637 cm −1 corresponded to absorbed Aryl C-H plane deformation, C-H plane deformation, and H2O stretching vibration (Pan et al 2016;Hao et al 2018). The whole cellulose liquefaction process needs a high temperature of 140 ℃.…”

Salix holocellulose liquefaction products (SHLP) were prepared by liquefaction of the wood. A spinning solution of polyurethane (PU) and SHLP was prepared, and microspheres were obtained by electrospinning. The bonding of SHLP and PU-SHLP was characterized via FTIR. The conductivity and viscosity of spinning solution were characterized by conductivity meter and viscosity meter, respectively. The electrospun fiber morphologies were characterized by SEM. The results showed that PU was introduced into SHLP. The concentration of solution was the main factor that affected the morphology of microspheres, and the diameters of microspheres was from 0.18 to 1.18 μm. In addition, in this electrospinning system, the concentration of liquefied products in the mixed spinning solution was the major factor that affected the morphology of microfibers, and the diameters of microfibers were from 0.29 to 1.78 μm.
