“…However, this energy loss has been ignored and this problem should be remediated. It was estimated that a 10% decrease of the dynamic hysteresis loss of the tire would save around 2% fuel consumption, [6,7] which would annually save 1-2 billion gallons of fuel consumed by the entire US passenger vehicle fleet. [8] A survey shows that contribution of the tire wear to the total amount of micro-plastics ending up in oceans is 5-10%, leading to significant environmental pollution.…”

One of environmental crises facing the world is due to rubber auto tires destruction pollution. Tires' exploitation in vehicles consumes 6 % of the world's energy and causes 5 % of carbon dioxide emissions; it releases up to 10 % of the microplastic pollution found in oceans.We designed a new rubber nanocomposite self-assembled from hard and soft elastomer matrixes: the polybutadiene with two hydroxy chain ends reacted with 4,4'-diphenylmethane diisocyanate to form segmented polyurethane. This system first undergoes a self-assembly, forming well-defined nanoscale hard domains distributed in the soft matrix. Then, cross-linking between the soft segments was accomplished by a controlled radiation method, resulting in the double network elastomer (DN-E). Remarkably, DN-E exhibited the lowest reported loss factor value at 60 o C. The index of energy dissipation in the rolling tire This article is protected by copyright.

These new double-network materials open a new prospective for design and fabrication of ultralow energy-consumption and strong abrasion-resistance elastomers, which establishes a milestone for the development of the next generation of green low pollution tires causing much less energy dissipation.

“…Hence, developing ways to reduce rolling resistance without sacrificing the grip efficiency has gained much attention during the last three decades both in academics and in the tire industry. 4,5 The rolling resistance, tread wear, and wet grip forming the so-called "magic triangle" of tire properties is a tire technology principle. 5 Before the invention of the silica−silane system, carbon black (CB) has been widely used as the main reinforcing filler in tire-tread compounding.…”

“…Tan δ (ratio of loss modulus to storage modulus) at about 60 and 10 °C, respectively, values were measured to assess the rolling resistance and wet grip efficiency of rubber samples. 4,14,15 Various PI-TESPT samples of different PI molecular weights were synthesized and compared against TESPT in rubber compounding to study the PI substitution effects. The effects of elemental sulfur on vulcanization characteristics and the corresponding rubber properties were investigated using PI 3 -TESPT with two different sulfur doses.…”

The coupling agent propyl] tetrasulfide) was modified by substituting polyisoprenyl (PI) carbanions for the ethoxyl groups on silicon for increasing the interaction of rubber with its fillers. The modification was carried out by the reaction of TESPT with polyisoprenyllithium, which had been previously prepared by anionic polymerization of isoprene using butyllithium. The success of the substitution was confirmed by Fourier-transform infrared spectroscopy, and the molecular weight of the modified TESPT (PI-TESPT) was determined from gel permeation chromatography measurements. The effects of tethered PI, as well as of its chain length, on the mechanical and dynamic properties of rubber compounds were examined using a universal testing machine and dynamic mechanical analysis (DMA). In rubber sample preparation, the amount of PI 3 -TESPT (PI of 2900 g/mol) used in rubber compounding is equal to that of the reference sample with TESPT (S TESPT ). For S PI-TESPT samples, the amounts of PI 6 -TESPT (PI of 5500 g/mol) and PI 14 -TESPT (PI of 13,700 g/mol) used were calculated as molar ethoxyl groups which are nearly equivalent to those of PI 3 -TESPT. At the same wt % (parts per hundred, phr) of elemental sulfur in rubber compounds, despite the order of cross-

A Janus Molecule for Screen‐Printable Conductive Carbon Ink for Composites with Superior Stretchability

et al. 2023

View full text Add to dashboard Cite

Inspired by decades of research in the compatibilization of fillers into elastomeric composites for high‐performance materials, a novel polyurethane‐based stretchable carbon ink is created by taking advantage of a Janus molecule, 2‐(2,5‐dimethyl‐1H‐pyrrol‐1‐yl)propane‐1,3‐diol (serinol pyrrole, SP). SP is used to functionalize the carbon and comonomer in the polymer phase. The use of SPs in both the organic and inorganic phases results in an improved interaction between the two phases. When printed, the functionalized material has a factor 1.5 lower resistance‐strain dependence when compared to its unfunctionalized analogue. This behavior is superior to commercially available carbon inks. To demonstrate the suitability of ink in an industrial application, an all‐printed, elastomer‐based force sensor is fabricated. This “pyrrole methodology” is scalable and broadly applicable, laying the foundation for the realization of printed functionalities with improved electromechanical performance.
