“…[ 25 ] Silica particles has hydroxyl groups on their surface which results in more filler–filler interactions, hence makes them polar and acidic. [ 26 ] This in turn cause the reduction of crosslink density in vulcanized elastomers. Furthermore, incorporation of high loading of silica significantly increase the viscosity, making processing more challenging.…”

Polymethylmethacrylate‐co‐methacrylic acid (PMMA‐co‐MAA) was utilized for surface improvement of silica to be used as reinforcement in self‐healing natural rubber based on metal thiolate ionic network. The amount of PMMA‐co‐MAA was varied at 1, 3, and 5 wt% of silica content and the optimized PMMA‐co‐MAA was utilized to investigate the self‐healing NR/silica composites at different filler loading (5, 10, 20, and 30 phr). The graft polymerization of PMMA‐co‐MAA on silica was confirmed using FTIR spectroscopy and grafting percentage was determined by thermogravimetric analysis (TGA). Intermolecular diffusion occurred at the fractured area was detected using a scanning electron microscope (SEM) and the results revealed that the composite tensile and tear performance increased 22%–70% with healing efficiency percentage ranging between 70% and 97% depending on the silica loading.

“…Silica (SiO 2 ) particles are widely used as reinforcing fillers in the manufacturing of rubber products. [14][15][16] In a study conducted by Sallat et al 17 self-healing butyl rubber composites were prepared by incorporating surface-treated silica particles with silane and alkoxysilane, which allowed for ionic interactions. The composites revealed superb tensile strength (18.9 MPa) due to the uniform distribution of silica particles.…”

This study aimed to explore the reinforcement effect of halloysite nanotubes (HNTs) in self‐healing natural rubber based on metal thiolate ion networks. The amount of HNTs was varied at five levels (2, 4, 6, 8, and 10 phr) in order to assess the optimum amount of filler for self‐healing efficiency and mechanical recovery performance. Fourier‐transform infrared (FTIR) provides evidence for the reversible ionic bonding, facilitated by Zn2+ and S− bonding from the metal thiolate vulcanization with rubber molecular chains. Scanning electron microscopy (SEM) revealed that the NR/HNTs composites with lower filler loading exhibited better recovery, as there were no observable gaps between the cut surfaces of the samples. The results also revealed that addition of HNTs resulted in a significant improvement in the mechanical performance, particularly the tensile strength, which increased by approximately 20%–75%. Furthermore, the extent of healing after the broken pieces were brought in contact with each other varied from 87% to 98%, depending on HNT concentration.Highlights Fabrication of self‐healing elastomers based on natural rubber. Self‐healing NR presented enhanced mechanical performance with addition of HNTs. HNTs lumen endows the composites with excellent self‐healing efficiency. Developed NR/HNTs composite exhibited room temperature self‐healing properties. Reversible ionic bonding expedited by Zn2+ contributes in excellent self‐healing.

Non-pneumatic tires (NPTs) have garnered significant attention due to their advantages, such as energy efficiency, safety, versatile applications, and superior performance, compared to traditional rubber-based pneumatic tires (PTs). This mini review provides a concise overview of NPTs, beginning with their definition, structural design, and classification based on structural variations. The review then examines recent advancements in the materials used for NPTs, including those for the tread, elastic support structure, skeleton, and adhesives, with a focus on their specific properties. Furthermore, it summarizes various manufacturing techniques such as compression molding, centrifugal casting, injection molding, 3D printing, and mechanical assembly. Lastly, the review outlines the general manufacturing procedures of NPTs, discusses the challenges currently faced by the technology, and offers insights into future development directions. This mini review aims to support NPT researchers and practitioners, particularly in the fields of process and materials engineering, in advancing their work on NPTs.
