“…Sample EP-OMMT5 showed the greatest increase in T g (21.5°C). The influence of clay particles on the T g of the epoxy coatings is not clearly understood and results are contradictory (Becker et al , 2002; Kornmann et al , 2002; Park & Jana, 2003; Nigam et al , 2004; Prolongo et al , 2010; Ferdosian et al , 2013; García del Cid et al , 2014; Motamedi et al , 2017). In general, the interaction between epoxy molecular chains and rigid clay layers, the plasticizing effect of clay ammonium-based modifiers on the epoxy molecular chains and the homo-polymerization of epoxy by clay ammonium-based modifiers may be responsible for the variation in the T g of the epoxy composite in previous studies.…”

Modification and characterization of an Iranian montmorillonite as a corrosion/mechanical promoter for epoxy coatings

Iranian montmorillonite (MMT) was modified with hexadecyltrimethylammonium bromide (HDTB) and used as a nano-additive for the enhancement of the mechanical and anticorrosion properties of an epoxy coating. Infrared (IR) spectroscopy, thermo-gravimetric analysis (TGA), transmission electron microscopy (TEM) and X-ray diffraction (XRD) analysis indicated that HDTB reacted with MMT (with 97% yield) and increased the d001 spacing of MMT from 1.27 to 3.92 nm. Some 1, 3 and 5 wt.% of organically modified montmorillonite (OMMT) were added to the epoxy coating formulation. XRD and TEM/image processing analysis showed that the extent of intercalation/exfoliation of OMMT was substantially greater than that of MMT. Dynamic mechanical analysis showed that the glass transition temperature and storage modulus increased significantly with the addition of OMMT. Electrochemical impedance spectroscopy (EIS) and salt spray/image processing results revealed that addition of OMMT to the epoxy coating significantly increased the corrosion resistance of the coating compared to neat and MMT-containing epoxy coatings. The optimum concentration of OMMT was 3 wt.%. At this concentration, the mechanical and anticorrosion properties were greatly superior to those of neat and MMT-containing epoxy coatings.

“…At first, epoxy resin was dissolved into n‐butyl alcohol/xylene blending solution (2 : 1 by volume) with mechanical stirring. Then, acrylic monomers were mixed at mass ratio of AA : MMA : 2‐EHA=3 : 2 : 5 with the added BPO as the initiator ,. The blending acrylic monomers were dropped into epoxy resin solution at 90 °C for 2 hours.…”

In this paper, a novel adhesive prepared by blending lithium‐ion functionalized epoxy resin (ionized oligomer) with poly(vinylidenedifluoride) (PVdF) is used to fabricate the cathode electrode of LiCoO2. The properties of the blending adhesive are studied by Fourier transform infrared spectroscopy, differential scanning calorimeter, and thermogravimetric analysis, and the morphology and performance of the composite cathodes are characterized by using X‐ray photoelectron spectroscopy (XPS), scanning and transmission electron microscopy, electrochemical impedance spectroscopy, and galvanostatic charge‐discharge. With the blended ionized oligomer, the crystallinity behavior of PVdF is decreased effectively, which will be beneficial to the movement of conducting ions. An appropriate amount of ionized oligomer effectively improves the conductivity and charge‐transfer capability of the cathode material. When the amount of ionized oligomer to the PVdF binder is 10 wt%, the LiCoO2‐based composite cathode delivers the highest charge−discharge capacity (178 mAh g−1) and the capacity retention is up to 82.2 % after 100 cycles.

“…The physical and rheological properties of bitumen can be determined from the content of hydrocarbon groups [12]. Increasing the content of asphaltenes, which leads to a more stable hardness of the bitumen structure [13]. Bitumen can be classified as sol and gel depending on its hydrocarbon group content.…”

There are numerous methods and additives available to improve the durability and quality of road bitumen. A coal tar obtained by coal coking was distilled in a laboratory into fractions of initial boiling point IBP-180˚C (gasoline-like fuel), 180˚C -360˚C (diesel-like fuel), and >360˚C (residue or coal tar pitch). The coal tar pitch was added into road bitumen by up to 1 -5 wt% and investigated the alteration of physical and chemical properties. The physico-mechanical properties of coal tar pitch and bitumen blends, as well as the chemical group composition, were determined using standard techniques (MNS) and the SARA method, respectively. Results of 3% coal tar pitch addition into bitumen enhanced ductility by 12.4% and softening point by 1.6˚C. We found that blending with bitumen coal tar pitch as a modifier could improve bitumen properties.
