“…There are many works focused on superhydrophobic epoxy resin (EP) coatings because of the excellent mechanical properties, low manufacturing cost, and their superior adhesion. For example, Zhang et al fabricated superhydrophobic EP/PDMS-SiO 2 coatings that were used for self-cleaning and resistance to gamma radiation. Despite the excellent self-cleaning ability and high gamma radiation stability of these materials, a large amount of silica may weaken the mechanical properties of the coating.…”

In this work, we converted inherently hydrophilic and flammable epoxy resins to resist both fire and water. This was achieved by integrating surface modified flame-retardant CoFe 2 O 4 nanoparticles into the epoxy resin. The modified CoFe 2 O 4 nanoparticles reduce the peak heat release rate, peak smoke production release and CO production in the CoFe 2 O 4 /epoxy resin nanocomposite by 39.6, 41.6, and 61.3%, respectively. The obtained flame retardant CoFe 2 O 4 /EP items demonstrate excellent durability with constant superhydrophobicity even after high external pressure, knife-scratch, and mechanical abrasion. In addition, the obtained items demonstrate outstanding robust water-repellent properties after facing longterm exposure to extremely corrosive liquids and also show self-cleaning properties in air and under oil.

“…For example, Zhang et al used epoxy/polydimethylsiloxane (EP/PDMS) resins as the matrix and silica nanoparticles as the fillers to prepare superhydrophobic surface. They found the contact angle of the epoxy/polydimethylsiloxane-SiO2 increased from 105° to 161°, and the structures was changed from bump to hollow grooves when the nano-SiO2 increased from 5 to 30 wt% [15]. Koao et al synthesized the octadecylammine (ODA)-capped ZnO nanostructures via the homogeneous precipitation method with annealing treatment.…”

“…Interfaces between PDMS and nanosilica played a vital role in resisting irradiation aging effects. Recently, Zhang et al 19 reported about utility of silica nanoparticles in modified epoxy resins for attaining stability against high γ-radiation. Madani reported on thermal analysis and electrical properties of EPDM composites incorporated with micro and nanosilica.…”

“…Nanocomposites of mSiO 2 and EPDM-CIIR blends of varying compositions were prepared by a binary-stage solid state mixing process. 18,19 The The rheometric characteristics, mechanical and viscoelastic behavior, solvent barrier properties, and thermal analysis were carried to study the effect of mSiO 2 . The suitability of Korsmeyer Peppas, Peppas Sahlin, and Highuchi models for sorption behavior has been evaluated to investigate the type of diffusion.…”

The study investigates the influence of bis(3‐triethoxysilylpropyl)tetrasulfide (TESPT) grafted nanosilica (NS) reinforcement on the mechanical, viscoelastic, thermal, and transport characteristics as well as behavior after exposure to different cumulative γ‐radiation doses of EPDM‐CIIR blends for application in nuclear and hydrocarbon environments. The tensile strength and modulus of the nanocomposites were enhanced upto 64% and 118%, respectively whereas solvent diffusion coefficient reduced by 22%. The degradation onset temperature improved from 485°C for unfilled blends to 503°C for the nanocomposites. γ‐radiation aging resistance of EPDM‐CIIR blends improved with incorporation of nanosilica, with blends containing 7.5phrNS showing optimum properties and radiation aging resistance. The property improvements are attributed to the dispersion of NS and chemically interfaced covalent linkages between SiO2‐EPDM/CIIR chains that provides large interfacial area for effective stress transfer and creates barrier to free radical and solvent permeation. The applicability of Korsmeyer‐Peppas, Peppas‐Sahlin, and Higuchi models to predict of sorption behavior are investigated. Coats‐Redfern and Horowitz‐Metzger models were employed to evaluate the activation energy for thermal degradation. Slight decline in properties at higher nanofiller contents was due to the formation of agglomerates. TEM, FTIR, and rheological curves were utilized to corroborate these observations. FTIR and ESR analysis provided insight on the chemical changes in the nanocomposites after irradiation.
