Carboxylated butadiene-nitrile latex (CBNL) elastomers possess several unique characteristics including excellent abrasion resistance and oil resistance. They are used in a wide variety of commercial and Defense applications. In this work, the effect of a newly developed graphene surfactant (GOS) on the thermal, mechanical and viscoelastic properties of vulcanized latex nanocomposites was studied. The latex was synthesized by emulsion polymerization and the vulcanized film without any filler had a tensile strength (TS) of 2.40 MPa and strain at break of 107%. Graphite filler (8 wt%) in combination with 2.6 wt% of GOS, added to the latex, increased the TS to 5.2 MPa and to 7.5 MPa with 10 wt% of the GOS, while the elongation at break was reduced to 48% and 30% for the latex nanocomposites, respectively. The vulcanized film without any graphite, but with 2.8 wt% of GOS had a TS of 7.8 MPa and a marginally increased elongation at break (88%), as compared to the graphite filled composites. The nanocomposites with graphite and GOS also showed higher damping characteristics, as indicated by the width of the tan δ peak, spanning over a broad temperature range of 100 °C for the sample with 2.6 wt% GOS and 8 wt% graphite. In summary, the work reports the development of potentially valuable damping materials from carboxylated nitrile latex using an amphiphilic polymer modified graphene surfactant in combination with graphite.

羧化丁二烯腈乳胶（CBNL）弹性体具有几个独特的特性，包括出色的耐磨性和耐油性。它们被广泛用于商业和国防应用。在这项工作中，研究了新开发的石墨烯表面活性剂（GOS）对硫化胶乳纳米复合材料的热，机械和粘弹性的影响。通过乳液聚合合成胶乳，并且不含任何填料的硫化膜具有2.40MPa的拉伸强度（TS）和107％的断裂应变。添加到乳胶中的石墨填料（8重量％）与2.6重量％的GOS结合使用，可将TS增至5.2 MPa，并在10重量％的GOS下提高至7.5 MPa，而断裂伸长率降低至48％和乳胶纳米复合材料分别为30％。不含任何石墨的硫化膜，但与填充石墨的复合材料相比，GOS含量为2.8 wt％时，TS值为7.8 MPa，断裂伸长率略有提高（88％）。tanδ峰的宽度表明，具有石墨和GOS的纳米复合材料还具有较高的阻尼特性，对于2.6 wt％的GOS和8 wt％的石墨，其跨度为100°C。总而言之，这项工作报告了使用两亲聚合物改性的石墨烯表面活性剂与石墨结合，从羧化丁腈胶乳中开发潜在有价值的阻尼材料的过程。含2.6 wt％GOS和8 wt％石墨的样品的温度范围为100°C。总而言之，这项工作报告了使用两亲聚合物改性的石墨烯表面活性剂与石墨结合，从羧化丁腈胶乳中开发潜在有价值的阻尼材料的过程。含2.6 wt％GOS和8 wt％石墨的样品的温度范围为100°C。总而言之，这项工作报告了使用两亲聚合物改性的石墨烯表面活性剂与石墨结合，从羧化丁腈胶乳中开发潜在有价值的阻尼材料的过程。
