Thermodynamic analyses of the hydrogen bond dissociation reaction and their effects on damping and compatibility capacities of polar small molecule/nitrile-butadiene rubber systems: Molecular simulation and experimental study

Designing a Polymer-Based Hybrid with Simultaneously Improved Mechanical and Damping Properties via a Multilayer Structure Construction: Structure Evolution and a Damping Mechanism

“…Besides, the tensile strength and elongation at break for PTP8 were 27.0 MPa and 925.1%, respectively. As mentioned in the introduction, HPs act as a plasticizer or anti-plasticizer in HP/polymer binary hybrids, which leads to the dramatic decrease of tensile strength and the dramatic increase of elongation at break of the hybrids [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Thus, the difference of the tensile strength and elongation at break between TP8 and PTP8 was mainly attributed to the plasticizing effect of AO-70 to TPU.…”

“…Therefore, by regulating the above three factors, a polymer/HP hybrid with an excellent tan δ value and potential application value in the industry can be obtained. However, because of the existence of the apparent defects, especially the significantly decreased mechanical property and the narrow damping temperature range [24][25][26][27][28], the application of such a promising damping hybrid is still limited so far.…”

Temperature dependence of the interfacial bonding characteristics of silica/styrene butadiene rubber composites: a molecular dynamics simulation study

“…Molecular dynamics (MD) simulation based on force elds has been demonstrated to be an effective tool for analyzing microstructures and predicting the macroscopic properties of polymers and their nanocomposites. [27][28][29] In the eld of MD simulation, great progress has been made on research about the interfacial characteristics of polymers lled with silica, graphene or carbon nanotubes. [30][31][32][33] One of the studied factors is the effect that the surface chemistry of the ller has on the interfacial properties of nanocomposites.…”

“…Compared with experimental methods with which the information on hydrogen bonds is indirect, MD simulation can intuitively give the type, number and evolution of hydrogen bonds as a function of temperature, pressure or time. 29,38 In this study, in-chain modied SBR models with various modier (3-mercaptopropionic acid) content were rst constructed. Then, the effect of temperature on the interfacial bonding characteristics of silica/SSBR composites was investigated at the molecular level using amorphous and layered models.…”

Pressure‐volume‐temperature properties and thermophysical analyses of AO‐60/NBR composites

“…The hindered phenol of tetrakis [methylene‐3‐(3‐5‐ditert‐butyl‐4‐hydroxy phenyl) propionyloxy] methane (AO‐60) is a common industrial antioxidant. Previous studies showed that the introduction of AO‐60 into nitrile‐butadiene rubber (NBR) can effectively improve the damping properties and aging resistance of the rubber, so AO‐60/NBR composites have very good prospects in industrial applications . However, the achievement of maximum damping and aging performances will affect the size stability of the rubber composites.…”
