A facile cross-linking strategy of using small molecules as physcial crosslinkers to facilitate recyclable polybutadiene (PB) elastomer with excellent toughness and stretchability is demonstrated. Carboxylic acid groups were incorporated along the PB backbone via thiol-ene reaction, and then the polymer can be cross-linked by ionic hydrogen bonds between the carboxylic acid groups from PB and the amine groups of the cross-linkers. The ionic hydrogen bonds can dynamiclly break and reconstruct upon deformation, thus endowing the resultant polymer with not only high toughness and stretchability (1800%), but also good selfrecovery and enhanced damping properties. Remarkably, the dynamically cross-linked PB elastomer can be thermally recycled owing to the thermal reversibility of the ionic hydrogen bonds and the mechanical properties can be largely recovered after reprocessing.

“…For example, in the aerospace and electronics and electric application, the polymer material often was adhered between the substrates of a different hardness and temperature . When the device suffers the constant vibration or temperature shock, mismatch of modulus or coefficient of thermal expansion between the substrate and polymer will cause breakage at interface . Further investigation shows that the PGMs enable larger energy dissipation for mechanical damping and exhibit broader damping temperature/frequency compared with the bilayer or homogenous materials …”

Polymeric gradient film consisting of the plastic nanoparticles in addition to an elastomer matrix was created by driving the charged sulfonated polystyrene (PS) nanoparticles in polydimethylsiloxane (PDMS) matrix under direct‐current electric field. The gradient morphology was frozen by thermal curing. The morphology, composition, damping, and mechanical properties of cured PS/PDMS gradient film containing 10 wt % of PS nanoparticles were measured with scanning electron microscopy, energy‐disperse spectroscopy, and dynamic thermal mechanic analysis and tensile test, respectively. In comparison with the isotropic PS/PDMS film, the gradient film shows a better damping property, and a higher tensile strength and elongation at breaking. The interpretation in terms of deformation and fracture mechanism of gradient structure was proposed. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48401.

“…Rubber damping materials used for reducing unwanted noises and preventing vibration failure are becoming increasingly significant in all kinds of motor vehicles, equipment and instruments, automatic office equipment and household appliances . In general, the values of the loss factor (tanδ) of high rubber damping materials are higher than 0.3 for a temperature range of 40–60 °C .…”

In this study, epoxidized high vinyl polybutadiene rubber (EHVBR) was prepared by the epoxidation reaction of high vinyl polybutadiene rubber (HVBR) in toluene using peroxyacetic acid as oxidant. The effects of reaction temperature and peroxyacetic acid concentration on the epoxidation degree of EHVBR were investigated by Fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR), and the damping properties of organic hybrids consisting of EHVBR and different contents of hindered phenols tetrakis [methylene‐3‐(3‐5‐di‐tert‐butyl‐4‐hydroxyphenyl) propionyloxy] methane (AO‐60) and 3,9‐bis[1,1‐dimethyl‐2{β‐(3‐tert‐butyl‐4‐hydroxy‐5‐methylphenyl)propionyloxy} ethyl]‐2,4,8,10‐tetraoxaspiro[5,5]undecane (AO‐80) were explored by dynamic mechanical analysis (DMA). FTIR and NMR analyses indicated that the epoxidation occurred on the C=C double bonds of HVBR molecular chains and the epoxidation degree of EHVBR could be adjusted from 5 to 65% through control of the reaction temperature and peroxyacetic acid concentration. DMA and physical mechanical measurements indicated that the introduction of AO‐60 and AO‐80 could simultaneously improve the damping properties and mechanical properties of the EHVBR/AO‐60 and EHVBR/AO‐80 hybrids. The blending ratios of EHVBR/AO‐60 = 100/60 and EHVBR/AO‐80 = 100/60 showed better damping properties and the effective damping temperature ranges were extended from 13.1 to 52.3 °C and from 16.1 to 54 °C, respectively. © 2018 Wiley Periodicals, Inc.
