“…Conventionally, the greater tan δ value of the rubber composites in the temperature region of −20 to 10 °C is an indication of the superior wet skid resistance of the rubber composites. The lower tan δ value of the rubber composites in the region of 60–80 °C indicates the low rolling resistance of rubber tires . Obviously, the ENR‐containing rubber composites have higher tan δ values in the region of −20 to 10 °C than that of S–UL, which indicates the improvement of the antiskid properties of the rubber composites under wet conditions.…”

The aggregation structure of lignin in aqueous solution had an important effect on the dispersion of lignin and the properties of lignin/styrene-butadiene rubber (SBR) composites. This article revealed the relationship between aggregation structure and chemical structure of modified lignin. Unmodified lignin was amorphous; however, our results showed that aldehyde-modified lignin was transformed into spherical aggregates, while propylene-oxide-modified lignin self-aggregated into supramolecular domains. The relationships between aggregation structure, filler dispersion, filler-rubber interaction, and performance were also studied by investigating the microstructure, viscoelastic behavior, and mechanical properties of lignin/SBR composites. Meanwhile, a solution to improve the coprecipitation efficiency of lignin and SBR latex was proposed. In this article, epoxidized natural rubber (ENR) was also used as compatibilizer to improve the interfacial adhesion between polar lignin and nonpolar SBR. The results showed better lignin dispersion for the ENR-containing rubber composites, as well as superior wet skid resistance and lower rolling resistance. V C 2017Wiley Periodicals, Inc. J. Appl.

“…The NG-barrier properties of the EPDM/CR nanorubbers were evaluated by measuring the NG absorptions of the nanorubbers [ 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. As shown in Figure 8 a, piled specimens, composed of six layers of propellant (in black) and five layers of nanorubber (in yellow), were prepared.…”

The triacetin and nitroglycerin barrier properties of layered-silicate reinforced ethylenepropylenediene monomer/chloroprene rubber (EPDM/CR) nanorubbers were investigated as rocket-propellant inhibitors. EPDM/CR nanorubbers with intercalated structures were formulated and prepared by the melt-compounding method. The triacetin permeability and nitroglycerin absorption were observed to decrease with increasing layered-silicate content. The layered silicates also improved the flame retardancies of the nanorubbers by forming silicate reinforced carbonaceous chars. Layered-silicate reinforced EPDM/CR nanorubbers are potentially effective rocket propellant-inhibiting materials.

The objective of this work is to develop graphene oxide (GO) incorporated butyl rubber (IIR) nanocomposites by three different methods: direct addition approach (DAAM), single step method (SSM) and two step method (TSM). Chlorobutyl rubber was used as a compatibilizer in SSM and TSM. Mechanical properties of developed nanocomposites was increased and gas permeability coefficient was decreased up on addition of GO content in IIR matrix. Maximum technical properties was achieved for the nanocomposite with 1.6 wt.% of GO in all methods was achieved due to better interfacial bonding with IIR matrix. When GO content increases above 1.6 wt.% in IIR matrix leads to agglomeration which resulted in deterioration of mechanical properties. HR-TEM studies revealed that nanocomposites prepared by TSM shows exfoliated structure of GO in IIR matrix due to homogenous distribution when compared to the nanocomposites prepared with DAAM and SSM.
