“…[ 1 , 2 , 3 ]. However, the majority of rubber is employed in the production of tires, where many attempts have been made to enhance the properties of vulcanized rubber compounds [ 4 , 5 ]. One possibility for improving the physical properties of vulcanized rubber compounds including stiffness, storage modulus, tear resistance and tensile strength is the incorporation of fillers into the rubber matrix prior to vulcanization [ 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ].…”

A set of poly(isobornyl methacrylate)s (PIBOMA) having molar mass in the range of 26,000–283,000 g mol−1 was prepared either via RAFT process or using free radical polymerization. These linear polymers demonstrated high glass transition temperatures (Tg up to 201 °C) and thermal stability (Tonset up to 230 °C). They were further applied as reinforcing agents in the preparation of the vulcanized rubber compositions based on poly(styrene butadiene rubber) (SBR). The influence of the PIBOMA content and molar mass on the cure characteristics, rheological and mechanical properties of rubber compounds were studied in detail. Moving die rheometry revealed that all rubber compounds filled with PIBOMA demonstrated higher torque increase values ΔS in comparison with rubber compositions without filler, independent of PIBOMA content or molar mass, thus confirming its reinforcing effect. Reinforcement via PIBOMA addition was also observed for vulcanized rubbers in the viscoelastic region and the rubbery plateau, i.e. from −20 to 180 °C, by dynamic mechanical thermal analysis. Notably, while at temperatures above ~125 °C, ultra-high-molecular-weight polyethylene (UHMWPE) rapidly loses its ability to provide reinforcement due to softening/melting, all PIBOMA resins maintained their ability to reinforce rubber matrix up to 180 °C. For rubber compositions containing 20 phr of PIBOMA, both tensile strength and elongation at break decreased with increasing PIBOMA molecular weight. In summary, PIBOMA, with its outstanding high Tg among known poly(methacrylates), may be used in the preparation of advanced high-stiffness rubber compositions, where it provides reinforcement above 120 °C and gives properties appropriate for a range of applications.

“…Most researchers have focused on improving the composites' performance by adding CNT to rubber. [22][23][24] However, the rheological properties also need to be well understood as they are closely related to the processing, manufacturing, and final properties of rubber composites. The rheological behaviors of rubber/CNT composites have been thus explored in academic research academia.…”

Effects of carbon nanotubes (CNTs) content and the in situ surface modification via bis(triethoxysilylpropyl) disulfide (Si75) and (3‐aminopropyl) triethoxysilane (KH550) on the rheological properties of rubber nanocomposites are explored. Results from the strain sweep demonstrate that the filler network of the nanocomposite is enhanced when the hydroxylated CNT (HCNT) is incorporated. The promotion of filler–rubber interaction in nanocomposite reinforced with modified CNT is validated by both stress relaxation and strain sweep measurements. The die swell ratio (B) declines with increasing HCNT content and rises with a heightened shear rate. Compared to those without HCNT, B of the nanocomposites, which contained 5 phr HCNT, decreased by 5.4%, 7.0%, and 17.3% at 50, 200, and 500 s−1, respectively. The Si75‐modified HCNT and the carboxylated CNT (CCNT) reduce the B‐value of the extrudates at 500 s−1 by 3.7% and 3.0%, respectively. However, the extrudates filled with KH550‐modified HCNT or CCNT showed a larger B due to pre‐crosslinking, as demonstrated by stress relaxation and swelling tests. Furthermore, it is also found that the application of KH550 has an acceleration effect on the curing reaction, increasing the curing efficiency by 8.5%.Highlights The promotion of filler–rubber interaction is validated by RPA. The dimensional stability of the composites is improved after incorporating CNT. The extrudates with Si75 exhibit a reduced B and improved surface morphology. CNT content increase raises MH, ML, and shortens the t10 of the composite.

“…Furthermore, the stiffness variation between alternating soft and hard structures can erect various obstacles in the interfaces to significantly hinder crack propagation by deflecting cracks. 13,14 Common hard fillers include silica, 15,16 carbon nanotubes 17,18 and fibers, 19,20 and so on. Among these, silica gains favor because of its cost effectiveness, versatility and practical value.…”

A new generation of elastomer is expected to incorporate exceptional healing, reprocessing, damage-tolerant capacity and outstanding strength and toughness in view of a sustainable society. To search a suitable method to perfectly match the overall performance is yet a formidable challenge. Here, a thermaltriggered self-healing polyurethane composite elastomer was fabricated by crosslinking isocyanate terminated polyurethane with amidoxime-modified silica particles. The rigid fillers (silica particles) can effectively dissipate energy under an external force. The prepared particles and elastomer were detailly characterized by various instruments. The developed elastomer (POUs@2SiPs) had great tensile strength (39.47 MPa), decent elongation at break (1056.51%), excellent toughness (170.58 MJ m À3 ) and outstanding fracture energy (81.14 KJ m À2 ). Meanwhile, the well-designed healing capability enabled the material to regain its original mechanical performance and integrity after damage. In addition, the reprocessibility granted material reusability to extend the service lifespan. This work is supposed to provide a meaningful strategy for developing the elastomer, which can effectively balance those conflict properties of mechanical strength, damage-tolerant capacity and self-healing.
