“…Because of the importance of the polar epoxy group, ENR can be used as a compatilizer in nonpolar rubber composites to improve the dispersion of polar fillers . Therefore, enhanced interaction between the polymer and particles can be obtained for their chemical or physical reaction . In our previous articles, the chemical reaction between the epoxy group and SiOH group in an ENR–silica model compound was investigated via Fourier transform infrared (FTIR) spectroscopy, X‐ray photoelectron spectroscopy, and X‐ray diffraction.…”

Epoxidized natural rubber (ENR)–silica hybrids without any other additives were prepared by an open‐mill mixing method at room temperature. The curing characteristics, crosslinking density, mechanical properties, and dynamical mechanical properties were investigated. The results indicate that the ENR–silica hybrid materials could be cured with silica as a crosslinking and reinforcing agent. Attenuated total reflection–Fourier transform infrared spectroscopy and solid‐state 13C‐NMR spectroscopy exposed the characteristics of the interfacial interaction in the hybrids and confirmed the existence of chemical bonds and hydrogen bonds between the epoxy group and SiOH. Scanning electron microscopy illustrated a good dispersion of silica in the ENR matrix. Meanwhile, the modulus at 100% elongation of the hybrid reached 9.64 MPa when 100‐phr silica was loaded; a similar trend was observed for the hardness. Finally, our findings might extend the concept of rubber curing and open a new space for making an environmentally friendly rubber composite. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

“…In addition, the epoxide groups in the ENR molecules are advantageous in polymer–inorganic composites. Recently, ENR/silica compounds have been successfully prepared without silane , and the dispersion of silica improved with the degree of epoxidation in ENR, indicating interactions between the silanol groups on silica surfaces and the epoxy groups in ENR molecules. ENR has also been used as a compatibilizer in rubber composites, including acrylonitrile butadiene rubber (NBR) and NR .…”

Epoxidized natural rubbers (ENRs) with three different epoxide contents (i.e., 20, 35, and 50 mol% indicated as ENR20, ENR35, and ENR50, respectively) were prepared. They were then reinforced with 3‐methyacryloxypropyl trimethoxysilane‐modified nanosilica (MPTS‐SiO2). Influence of epoxide level in ENR molecules on morphological, mechanical, and dynamic mechanical properties of the ENR nanocomposites was investigated. The scanning electron microscopy results revealed larger agglomerates of SiO2 were found in the ENR composites with higher epoxide content. Furthermore, the strength and moduli of the ENR nanocomposites increased with increasing epoxide content. However, the optimal tensile strength and elongation at break were observed in the nanocomposites with the intermediate level of epoxide contents. The correlation between the strength properties and the interfacial silica‐matrix adhesion indicated that the maximum interfacial adhesion of the nanocomposites was observed in the nanocomposite with ENR35. Also, DMA results indicated stronger interaction between ENR35 and MPTS‐SiO2 due to higher storage modulus. POLYM. COMPOS., 38:1151–1157, 2017. © 2015 Society of Plastics Engineers

“…So the scorch time and optimum time were less than the compounds with the fumed silica that have studied in previous research [10] . That was because precipitated silica had bigger particle size and lower surface area, and didn't absorb more accelerant.…”

Abstract. ENR40/ precipitated silica (P-silica) compounds were prepared by in an open two-roll laboratory mixing mill at 50～60 ℃. Curing properties and mechanical properties was investigated. In order to reveal the interaction between ENR40 and P-silica, ENR40/P-silica compounds were extracted in toluene to obtain the bonding rubber content. Interfacial interaction of ENR40/P-silica was investigated by Fourier transform infrared spectroscopy (FTIR). The results indicated that during mixing process, ENR and silica had hydrogen bond and chemical interaction.
