| 中文摘要: |
| 将具有良好水分散性的氧化石墨烯（GO）与高导热填料氮化硼（BN）纳米片反应，生成GO负载BN（BN@GO）导热填料，采用胶乳共混法制备BN@GO/天然胶（NR）复合材料，研究BN@GO的结构和复合材料的性能。结果表明：GO通过共价键紧紧包覆BN纳米片，改善了BN纳米片与橡胶基体之间的相容性，BN@GO更易在橡胶基体中形成导热网络结构；当填导热填料质量分数为20%时，填充BN@GO的BN@GO/NR复合材料的导热性能优异，与填充BN纳米片的NR复合材料相比，BN@GO/NR复合材料的热导率、拉伸强度和撕裂强度分别提高了48.5%，55.0%和44.5%。 |

| Graphene oxide（GO）with good water dispersibility was reacted with high thermal conductivity filler boron nitride（BN）nanosheets to generate GO-supported BN（BN@GO）thermal conductive filler，prepared by latex blending method BN@GO/Natural rubber（NR）composites，research BN@GO structure and properties of composites.The results showed that GO tightly coated BN nanosheets through covalent bonds，improving the compatibility between BN nanosheets and the rubber matrix，BN@GO was easier to form a thermal conductive network structure in the rubber matrix；when the mass fraction of thermal conductive filler was 20%，the filling BN@GO of BN@GO/NR composites was excellent，compared to the NR composite material filled with BN nanosheets，the thermal conductivity，tensile strength and tear strength of BN@GO/NR composites increased by 48.5%，55.0% and 44.5%，respectively. |
