Carbon nanotube polymeric composites are widely developed as piezoresistive sensors. Despite these materials showed improved mechanical stability, they are less sensible than carbon aerogel. Moreover, the piezoresistive properties of these nanocomposites cannot be tuned to adapt the sensor to the different applications. Here we observed as modifying solvent dilution in the hard template synthetic route, allow for the fabrication of porous piezoresistive nanocomposites with different limits of detection, working ranges and sensitivities. More in details three different foams with diverse features were produced. Although all the three materials presented outstanding performances, the porous material prepared at higher dilution showed an incredible limit of detection for displacement (∼50 nm) and pressure (0.2 Pa) that are respectively 2.6 and 10 times lower than that recorded at lower prepolymer dilutions. However lower dilutions allow to produce sensors able to monitor larger pressures ranges (up to ∼150 kPa), which are 3 times higher than that of recorded in composites prepared at higher dilutions. Moreover, all the materials evidenced fast response time and high mechanical and electronics stability. Therefore, we demonstrated as this approach easily allows the synthesis of nanocomposites with improved performances and different sensing properties that can be tuned depending on the needed application with an unprecedent flexibility.

碳纳米管聚合物复合材料被广泛开发为压阻传感器。尽管这些材料显示出更高的机械稳定性，但它们不如碳气凝胶敏感。此外，无法调整这些纳米复合材料的压阻特性以使传感器适应不同的应用。在这里，我们观察到在硬模板合成路线中修改溶剂稀释，允许制造具有不同检测限、工作范围和灵敏度的多孔压阻纳米复合材料。更详细地，生产了三种具有不同特征的不同泡沫。尽管这三种材料都表现出出色的性能，但在较高稀释度下制备的多孔材料显示出令人难以置信的检测极限，位移 (~50 nm) 和压力 (0.2 Pa) 分别为 2。比在较低预聚物稀释度下记录的低 6 倍和 10 倍。然而，较低的稀释度允许生产能够监测更大压力范围（高达 ∼150 kPa）的传感器，这比在较高稀释度下制备的复合材料中记录的压力高 3 倍。此外，所有材料都证明了快速响应时间和高机械和电子稳定性。因此，我们证明了这种方法可以轻松合成具有改进性能和不同传感特性的纳米复合材料，这些纳米复合材料可以根据所需的应用进行调整，具有前所未有的灵活性。这比在更高稀释度下制备的复合材料中记录的高 3 倍。此外，所有材料都证明了快速响应时间和高机械和电子稳定性。因此，我们证明了这种方法可以轻松合成具有改进性能和不同传感特性的纳米复合材料，这些纳米复合材料可以根据所需的应用进行调整，具有前所未有的灵活性。这比在更高稀释度下制备的复合材料中记录的高 3 倍。此外，所有材料都证明了快速响应时间和高机械和电子稳定性。因此，我们证明了这种方法可以轻松合成具有改进性能和不同传感特性的纳米复合材料，这些纳米复合材料可以根据所需的应用进行调整，具有前所未有的灵活性。
