Summary: With the increase in waste rubber products, the pressure on the environment and resources is becoming more serious. The use of reclaimed rubber (RR) is a practical method to address this challenge. This study explores the reinforcement behavior of RR when different contents of natural rubber (NR) matrix are replaced by RR. The results show that the crosslinking density, Payne effect, and modulus increase with the increase in RR content until 60 phr, but decreases at 80 phr. SEM observation confirms that both NR and RR constitute co-continuous phases at 60 phr, while RR becomes the only continuous phase at 80 phr. The curing rate is also enhanced with higher RR content, and structures with high crosslinking density are found in the NR matrix filled with RR. Furthermore, carbon black in RR, high crosslinking density, and a continuous rubber matrix are important factors influencing the reinforcement behavior in RR filled rubber composites.

Summary: Silver nanowires (AgNWs) are promising materials for transparent conductive electrodes in optoelectronic devices, but their practical use is hindered by corrosion under ambient conditions. This study presents a novel approach using a transparent synthetic rubber, TBR, as a stretchable substrate and a protective gas barrier, which effectively prevents corrosion and enhances the durability of AgNW networks.

Summary: In this paper, a new synthesis process was used to prepare solvent-free fluid Fe3O4 (S-Fe3O4) by surface modification of solid Fe3O4, which showed excellent dispersion in resin materials. Moreover, S-Fe3O4 was compounded with CNT@Fe3O4 to prepare S-Fe3O4/CNT@Fe3O4/EP composites, which realized the multiple loss mechanism of electromagnetic wave (EMW) absorption. This surface molecular engineering composite based on inorganic particles enhanced the attenuation ability of EMW by improving the dispersion of inorganic particles and providing multiple loss mechanisms.

Summary: Natural rubber latex filled with silica can be used to prepare low-cost green tires with low rolling resistance, but the difficulty lies in the low mixing efficiency and reduction of properties. This paper proposes a strategy for preparing NR/silica composites that improve dispersion and interfacial adhesion, resulting in composites with enhanced performance. The strategy provides new research avenues for the preparation of green tires and other rubber industries in the future.

Summary: The development of flexible and lightweight microwave-absorbing materials has become a trendy topic. This study focuses on enhancing the microwave-absorbing performance of butadiene-acrylonitrile rubber (NBR) by incorporating novel reinforcing nanofillers. The results show that the NBR nanocomposite with a loading of 16 parts per hundred rubber (phr) of LiFe 20%/Si has the best microwave-absorbing performance.

Summary: This paper discusses the fatigue life analysis of a blend of natural rubber and styrene-butadiene rubber with and without nanoclay particles using finite element analysis. The study finds that damage parameters based on strain can effectively estimate the fatigue lives, and the predicted fatigue life matches well with the measured fatigue results. Additionally, the effect of various parameters and the fracture surface of the nanocomposite are investigated.

Summary: This study investigated cavitation phenomena in silica-filled styrene-butadiene-rubber composite during cyclic tensile testing before and after thermal exposure, using 3D digital image correlation and micro-computed x-ray tomography techniques. The results showed that thermal exposure led to structural changes in the composite, such as increased crosslink density and stiffness of the rubber matrix. It was observed that the thermally-treated composite exhibited higher mechanical hysteresis and volume strain during testing.

Summary: Indialite/cordierite (Mg2Al4Si5O18) glass-ceramics with low dielectric constant and high Qf are potential materials for micro/millimeter-wave applications in 5G mobile communication systems. The addition of TiO2 was found to prevent cracking during surface crystallization, resulting in the formation of spherical crystals and specific precipitated phases. The reaction between cordierite and TiO2 produced the new Al2TiO5 phase, influencing the microwave dielectric properties.
