“…This pattern compares well with the experimental pattern of Na-Bentonite reported in the Powder Diffraction File under the JCPDS Card No. 003-0019; is in very good agreement with earlier works [10,30,31]. After intercalation with TBHSA, the basal spacing, d001, of the resulting product becomes 14.56 Å; indicating the successful of the intercalation method.…”

This study focuses on the synthesis, characterization, and application of amphiphilic PCL-PEG-PCL/Bentonite-TBHSA (A2). The prepared of A2 nanocomposite was prepared from Algerian Bentonite modified by the intercalation of tetrabutylammonium hydrogen sulfate (TBHSA) (A1), were characterized by different techniques including Fourier transform infrared spectroscopy (FTIR), X-ray diffraction(XRD), (TEM),(DSC) and thermogravimetric analysis (TGA ). The removal efficiency of of methylene blue, from aqueous solutions. The effects of the initial pH of a solution, contact time, and nanocomposite mass on the adsorption efficiency were investigated. Pseudo-first/second-order isotherms were applied to determine the efficiency of nanocomposite solid. The experimental data fitted well with the pseudo-second-order model for MB dye adsorption. The mass of nanocomposite increased, the adsorption capacity of dye increases to reach an optimal value at 0.13 g of adsorbent in pH = 6.8. The Langmuir isotherm exhibited the best fit, with an adsorption capacity equal to 600 mg/g .

This work is mainly concentrated on the preparation and characterization of poly(propylene oxide) (PPO)/organic clay nanocomposites. The effects of the nature of organoclays and the method of preparation have been elucidated to evaluate their morphological, structural and thermal properties. These nanocomposites were characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, thermal analysis (differential scanning calorimetry) and thermogravimetric analysis (TGA). This study involved the use of an Algerian clay called ‘maghnite’ which was modified by an incorporation method using different concentrations of the surfactant cetyltrimethylammonium bromide (CTAB). Propylene oxide (PO) was polymerized in the presence of ethylene glycol and various proportions of organic clay ranging from 1%, 5% and 10% by weight. The structural study by XRD showed, at different loading rates of maghnite and PO in the preparation of PPO/maghnite nanocomposites, different morphologies: intercalated/exfoliated blend and intercalated/agglomerated. TGA showed that the intercalation of PPO at the montmorillonite (MMT)-CTA interface would be more advantageous since the required amount of 5% organic clay (by weight) ensures high thermal stability of the nanocomposites, and the glass transition temperature ( T g) of PPO/MMT nanocomposites is higher than that of PPO since this increase is due to the introduction of clay into the matrix which makes the nanocomposite more rigid.

“…The results showed that the bonding system containing m-phenylenediamine presented a higher adhesion level between rubber and fabrics than that containing o-aminophenol. Moustafa [14] observed the bonding properties between expanded organoclay (EOC) modified EPDM rubber and polyester fabric, and analyzed the reaction mechanism of EOC with the EPDM/ polyester fabric in the presence of a bio-alkyd resin. Additionally, this research also evaluated the bond strength between EPDM rubber and polyester fabric through peel test.…”

Effects of titanate on the bonding properties of silicone rubber and polyester fabric

et al. 2021

View full text Add to dashboard Cite

The effects of titanate on the mechanical properties of silicone rubber and peel strength of polyester fabric with silicone rubber are studied. The tests show that the hardness and mechanical properties of silicone rubber containing 0.2 phr titanate are similar to those of pure silicone rubber, and the peel strength (1.11 N/mm) between fabric and rubber matrix without inner fabric is the highest in the test groups. Fourier transform infrared spectra (FT-IR) and contact angle test indicate that the surface wettability of silicone rubber is effectively enhanced with the addition of titanate, which is a key factor to improve the bonding properties between silicone rubber and polyester fabric because of the more adequate contact between the adhesive and silicone rubber surface.Due to the difference in the modulus of the fabric along different yarn directions, the peel direction has a significant effect on the peel force between the outer fabric and silicone rubber.
