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.

“…Since the first invention of nanogenerators in 2006, different types of nanogenerators based on piezoelectric effect, [1][2][3] pyroelectric effect, [4][5][6][7] and triboelectric effect [8] have emerged one after another. Among these nanogenerators, triboelectric nanogenerators (TENGs) [9][10][11][12][13][14] have become the most eye-catching technology because of their high efficiency and simple manufacturing process.…”

Triboelectric nanogenerator (TENG) is an effective approach for self-powered systems. Here, a second-order Rubik-cube-based TENG (SRC-TENG) is designed, which can harvest the internal sliding energy of the Rubik cube. The influence of different rotation speeds, different strengths, and effective contact area on the output performance of SRC-TENG is studied. When the SRC-TENG rotates with a high speed, light strength, and the contact area is 8 cm 2 , the maximum open-circuit voltage and short-circuit current can reach up to 35 V and 1.45 µA, respectively, which are enough to light up dozens of light-emitting diodes (LEDs) and charge commercial capacitors. In addition, the SRC-TENG-based smart toys can act as self-powered sensors to be applied in smart home. More importantly, the movement trajectory of the Rubik cube in the process of recovery can also be tracked in different directions of X, Y, and Z. The proposed SRC-TENG is low cost and has great potential to replace battery-powered electronic toys, which can open a new path for the next-generation commercial toys.

“…“Rubbers” are a member of a class of polymers known as “elastomers”, i.e., polymers that are characterized by large strain, low-modulus extensibility, and instantaneous and complete recovery after removal of the load. After stretching and deformation, they can return to the original shape. − The rubber retains an exclusive place in modern technology, due to its exceptional strength and tack in the prevulcanized state, and advanced crack-growth resistance and excellent mechanical performance once vulcanized. , The vulcanization process by which rubber is heated with sulfur and other additives to create a chemically cross-linked network was invented in 1839 by Charles Goodyear. − The unaccelerated vulcanization procedure applied elemental sulfur at 8 parts per 100 parts of rubber (8 phr) and an essential temperature of 143 °C for 6 h. It is desirable to accelerate the rate of vulcanization to lower energy/resource consumption and reach higher productivity. , By adding a few parts of the organic accelerators, the vulcanization time was reduced massively . Further, cross-linking formed a 3-D network structure, mainly coming from single, bisulfide, and polysulfide bonds, the yield of which depended on the quantities and forms of the vulcanization reagents and additives, such as the rubber precursors, activators (ZnO), fatty acids, accelerators, and antioxidants …”

The vulcanization of rubber is a chemical process to improve the mechanical properties by cross-linking unsaturated polymer chains. Zinc oxide (ZnO) acts as an activator, boosting the rubbers’ sulfur vulcanization. Maintaining the level of ZnO content in the rubber compounds as low as possible is desirable, not only for economic reasons but also to reduce the environmental footprint of the process. In this contribution, octylamine (OA) capped ZnO nanoparticles (5 nm diameter), prepared through a thermal decomposition method, were demonstrated to be efficient activators for the sulfur vulcanization of natural rubber, enabling the reduction of the required amount of ZnO as compared to commercial systems. The effect of different ZnO activators (OA capped ZnO/commercial indirect process ZnO) on the curing characteristics, cross-linking densities, and mechanical performance, as well as the thermal behavior of rubber compounds, were investigated. Compared to the commercial indirect process ZnO, OA capped ZnO nanoparticles not only effectively enhanced the curing efficiency of natural rubber but also improved the mechanical performance of the composites after vulcanization. This was interpreted as, by applying the OA capped ZnO nanoparticles, the ZnO levels in rubber compounding were significantly reduced under the industrial vulcanization condition (151 °C, 30 min).
