Invented by Charles Goodyear, chemical cross-linking of rubbers sulfur vulcanization is the only method which modern automobile tires are manufactured. The formation these cross-linked network structures leads to highly elastic properties, substantially reduces viscous properties materials. Here, we describe a simple approach converting commercially available and widely used bromobutyl rubber (BIIR) into material with extraordinary self-healing without using conventional or vulcanising...

A detail study concerning the strain (tensile) dependent electrical conductivity of elastomeric composites is reported in this present paper. Multiwall carbon nanotubes (CNT), conducting black (CB), and their combinations were considered as filler cross-linked natural rubber matrix. The loadings fillers from 3 to 11 phr (filler concentration close percolation threshold). Without hindering elastic nature composite (reversible stretchability up several 100%), change relative resistance, ΔR/R0...

In the present work, a strong filler–filler network of conductive carbon black was strategically established in an elastomer matrix, which leads to unique combination electrical and mechanical properties. The novelty our composites development percolated morphology nanostructured conducting particles by incorporation relatively large nonreinforcing spherical silica particles, inside soft matrix. This technique allowed us fabricate solution styrene butadiene rubber (S-SBR) with outstanding...

Chemical cross-linking of rubber is a process to significantly modify the physical properties polymer. By this transformation, highly viscous compound converted into an elastomer suitable for high-performance products like tires. Conventionally, sulfur or peroxide preferred mode vulcanization polymer practiced by different industries. To fulfill growing demand more durable, products, development self-healing considered one most promising approaches. The present study endeavor mimic property...

Epoxidized natural rubber (ENR) was grafted with imidazolium ions, giving the materials self-healing and reprocessing properties. These ions in form of neutral ionic repeating units transformed polyisoprene-based polymer chains into ionomers. Fourier transform infrared (FTIR) spectroscopy solid-state nuclear magnetic resonance (NMR) analyses were carried out to confirm various interactions between ENR 1H-imidazole. In particular, dynamic hydrogen bonding formation aggregates led superior...

Template-assisted colloidal self-assembly has gained significant attention due to its flexibility and versatility. By precisely controlling the shape of template, it is possible achieve custom-designed nanoparticle assemblies. However, a major challenge remains in fabricating these templates over large areas at low cost. Recently, one-dimensional (1D) nano-wrinkle structures have been effectively used for linear assembly single-chain or multi-chain nanoparticles, which feature abundant...
