“…The electron micrographs from the SEM study are presented in Figure 1. Figure 1 20 4 It is clear that the initial elongated fiber like structure of cotton is preserved after hydrolysis with sulphuric acid, which is also in accordance with the previous study [14]. During the hydrolysis at the same acid concentration, the increased reaction temperature and time tends to break and further shorten the fibrous structure of MCC particles.…”

“…Figure 3 [19]. These XRD patterns represent different crystal lattice type of cellulose compared to the previous MCC studies from cotton plant sources, which mainly showed cellulose I type [12][13][14][15][16]. The transformation of cellulose I to cellulose II can be happened due to dissolution or regeneration and swelling of cellulose in a concentrated alkali [20].…”

“…In Avicel PH-101, the absorption bands appear at 3375 cm -1 which corresponds to the stretching vibration of -OH groups in cellulose and also at 2999 cm -1 which represents C-H stretching vibrations of -CH2groups. The absorption band at 1641 cm -1 corresponds to the -OH bending of adsorbed water mingled with C=O in the aldehyde on the terminal anhydroglucose unit [14]. This is related to the water molecules bending modes due to a strong interaction between cellulose and water [9].…”

Cotton wastes from cotton yarn spinning mills has been utilized as an alternative resource for the production of Microcrystalline Cellulose (MCC), an important ingredient in food, cosmetic, pharmaceutical industries, etc. The main processes conducted including cotton wastes sorting, cotton lint pretreatment, and alpha cellulose hydrolysis. In this study, several parameters on pretreatment and hydrolysis were varied in order to produce MCC which characteristics were evaluated comparing to Avicel PH-101, a commercial MCC product. Pretreatment was carried out using 17.5% alkali (w/v) at temperature 80 o C for 30 minutes, followed by a bleaching process at 5-30% H2O2 (v/v). The hydrolysis reaction was done using 1.25 M sulfuric acid, at temperature 80 o C and 96 o C for 2-4 hours. Results showed that pretreatment process with alkali for 30 minutes followed by a bleaching process with 5% H2O2 (v/v) was able to isolate 87% alpha cellulose with 99.98% of purity. The yields of MCC powders produced from acid hydrolysis of alpha cellulose at 96 o C for 2, 3, and 4 hours were 74.6%, 70.2%, and 42.8%, respectively. According to the SEM, infrared spectra, and XRD results, the process conducted was applicable to produce MCC that physically and chemically similar to the characteristics of Avicel PH-101.

Although coating technology and in‐situ synthesis have been widely applied to produce Fe3O4 NPs‐containing composite materials, there still exist potential risks to the environment. Herein, an eco‐friendly preparation of Fe3O4 nanoparticles (FNPs)‐coated wool felt is proposed based on the self‐glue effect of wool keratins in the NaHSO3/urea solution. It avoids the use of coating agents, and also the commercially available FNPs are directly utilized as raw materials, both making the residual FNPs completely recyclable. The resulting FNPs‐coated wool felt shows high magnetization (23.54 emu g−1) and excellent microwave‐assisted heating properties (the temperature rise is about 40°C after 10 min). The results of EDS‐SEM (energy dispersive spectrometer‐scanning electron microscope), loud amount (%), crease recovery angle (CRA), Fourier transform infrared (FTIR) spectrometer and X‐ray diffraction (XRD) prove that the dramatical swelling and the recoagulation of superficial keratins of wool fibers are the mechanism of the self‐glue effect.

The objective of this investigation is to find a less‐expensive and less‐toxic environmentally benign route for the preparation of magnetic PANI nanocomposite particles. For this citric acid, a weak organic tricarboxylic acid has been used during seeded chemical oxidative polymerization of aniline in presence of variable amounts of Fe3O4 nanoparticles. Nanosized Fe3O4 particles are first prepared by co‐precipitation of Fe2+ and Fe3+ from their alkaline solutions. Then in the second step, magnetic nanocomposite particles—named as Fe3O4/PANI—are prepared by seeded chemical oxidative polymerization of aniline using ammonium persulfate (APS) as oxidant. Independent of Fe3O4 content, Fe3O4/PANI nanocomposite particles possessed comparable high electrical conductivity having the same magnitude as HCl‐doped PANI particles (2.13 × 10−3 S/cm). This result suggested that addition of citric acid during seeded chemical oxidative polymerization not only promoted solubilization of aniline but also functioned as stabilizer and doping agent. Iron oxide content critically influenced the stability, morphology, and magnetic properties of the produced nanocomposite particles. The saturation magnetization and magnetic susceptibility increased with the increase of Fe3O4 content. The nanocomposite particles prepared with core/shell ratio of 0.6/1 (w/w) exhibited the strongest paramagnetism and aligned into fiber‐like structure. The analysis of electromagnetic properties and spectral data from FTIR, X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), and thermogravimetry (TG) confirmed the complete coverage of Fe3O4 nanoparticles by PANI layer.
