Graphene oxide prepared by the Hummers method was chemically modified by 3-aminopropyltriethoxysilane and spherical [email protected] graphene-oxide particles ([email protected]) with a core-shell structure were obtained by an emulsion method. [email protected] filler/silicone rubber (SIR) matrix composites ([email protected]/SIR) were prepared by dispersing different amounts of [email protected] in the SIR precursors, followed by curing and used as thermal interface materials (TIMs). Results indicate that the best TIM had a [email protected] loading of 60 wt.% and had both a high thermal conductivity (1.248 W·m⁻¹·K⁻¹) and a high latent heat (88.7 J·g⁻¹). Its compression elastic modulus (1.01 MPa) was only one-eighth of that of the pristine SIR (8.16 MPa) due to the plasticity of the paraffin. The paraffin leakage under pressure was low (below 3.98 wt.%) before and after thermal cycling 50 times. These favorable thermal and mechanical properties together with the good cycling stability make it a promising TIM for electronic devices.

用3-氨基丙基三乙氧基硅烷对通过Hummers方法制备的氧化石墨烯进行化学改性，并通过乳液法获得具有核-壳结构的球形[电子邮件保护]氧化石墨烯颗粒（[电子邮件保护]）。[电子邮件保护]填料/硅橡胶（SIR）基复合材料（[电子邮件保护] / SIR）是通过将不同量的[电子邮件保护]分散在SIR前体中制备的，然后进行固化并用作热界面材料（TIMs）。结果表明，最佳的TIM具有60 wt。％的[电子邮件保护]负载，并且具有高导热率（1.248 W·m ^-1 ·K ^-1）和高潜热（88.7 J·g ^-1））。由于石蜡的可塑性，其压缩弹性模量（1.01 MPa）仅是原始SIR（8.16 MPa）的八分之一。在热循环50次之前和之后，在压力下石蜡的泄漏低（低于3.98wt。％）。这些良好的热和机械性能以及良好的循环稳定性使其成为电子设备的有前途的TIM。
