Using an experimental approach, the effectiveness of nonionic surfactant, Triton™-X-100 in dispersing nano Alumina in high temperature vulcanized silicone rubber are studied in detail. Nanocomposites are prepared in varying concentrations of 0, 0.01, 0.05, 0.2, 1, and 5 phr levels by weight of the surfactant. Evidence to moderate dispersion of nano Alumina for composites at 0.01 phr and 0.05 phr weight loadings is gained from SEM pictures. Structural changes observed for the composites in FTIR spectra are examined and peaks identified. Thermogravimetric analysis shows some improvement in thermal resistance. However, an adverse effect on properties, such as volume resistivity, surface resistivity and dissipation factor are observed even at low surfactant loadings. A plausible role of surfactant as a plasticizer is explained with respect to the results of tensile strength. From this work, it can be inferred that surfactant at 0.01 phr may be taken as an optimum loading concentration for a desirable level of electrical properties, without compromising on insulation characteristics of volume resistivity and dissipation factor. Nonetheless, utmost caution needs to be exercised while employing Triton™-X-100 in compositions prepared for insulation applications because of inadequacies in values of volume resistivity, surface resistivity, dissipation factor and dry arc resistance even at low loadings.

表面活性剂改性 HTV-SiR/纳米氧化铝复合材料的光谱、机械和电学研究

使用实验方法，详细研究了非离子表面活性剂 Triton™-X-100 在将纳米氧化铝分散在高温硫化硅橡胶中的效果。纳米复合材料以表面活性剂重量的 0、0.01、0.05、0.2、1 和 5 phr 水平的不同浓度制备。从 SEM 照片中获得了在 0.01 phr 和 0.05 phr 重量负载下对复合材料的纳米氧化铝适度分散的证据。检查在 FTIR 光谱中观察到的复合材料的结构变化并确定峰。热重分析显示热阻有所改善。然而，即使在低表面活性剂负载下，也会观察到对诸如体积电阻率、表面电阻率和耗散因数等性质的不利影响。关于拉伸强度的结果解释了表面活性剂作为增塑剂的合理作用。从这项工作中，可以推断出 0.01 phr 的表面活性剂可以作为理想的电性能水平的最佳负载浓度，而不会影响体积电阻率和损耗因数的绝缘特性。尽管如此，在为绝缘应用制备的组合物中使用 Triton™-X-100 时需要格外小心，因为即使在低负载下，体积电阻率、表面电阻率、损耗因数和干电弧电阻的值也不足。在不影响体积电阻率和损耗因数的绝缘特性的情况下。尽管如此，在为绝缘应用制备的组合物中使用 Triton™-X-100 时需要格外小心，因为即使在低负载下，体积电阻率、表面电阻率、损耗因数和干电弧电阻的值也不足。在不影响体积电阻率和损耗因数的绝缘特性的情况下。尽管如此，在为绝缘应用制备的组合物中使用 Triton™-X-100 时需要格外小心，因为即使在低负载下，体积电阻率、表面电阻率、损耗因数和干电弧电阻的值也不足。
