柔性衬底PDMS过程数据

本数据测试了柔性传感器封装结构中的关键材料-衬底材料PDMS的可拉伸性弹性数据。所用测试设备为电脑式双柱伺服拉力试验机（型号规格为XM-SFC001-2）。轴向应变拉伸率（%）数据、轴向拉伸力（N）数据由测试设备直接导出。在具有大拉伸性能的柔性传感器的封装过程中，具有大拉伸能力的高弹性衬底是所有封装工艺的基础，衬底的弹性决定了传感器的可拉伸性能的极限。通过计算和反复筛选，最终选择制备热塑性弹性体聚二甲基硅氧烷（C2H6OSi，polydimethylsiloxane，PDMS）这种无毒安全的双组分液态硅胶膜作为传感器功能层的衬底材料，并测试了在逐渐增加单轴向拉伸力情况下的PDMS拉伸率变化曲线过程数据，数据中第一列作为x轴，第二列作为y轴，作图，最终获得断裂伸长率≥300%的PDMS超高弹性薄膜衬底。该数据作为研制过程数据，衬底的弹性和可恢复能力对于柔性传感器的可延展性起到关键作用。This dataset characterizes the stretchability and elastic properties of PDMS, the critical substrate material in the packaging structure of flexible sensors. The testing equipment used is a computer-controlled dual-column servo tensile testing machine (model specification: XM-SFC001-2). Axial elongation strain (%) data and axial tensile force (N) data were directly exported from the testing equipment. In the packaging of high-stretch flexible sensors, highly elastic substrates with exceptional stretchability serve as the foundation for all packaging workflows; the elasticity of the substrate dictates the upper limit of the sensor's stretchable performance. Through calculation and repeated screening, thermoplastic elastomer polydimethylsiloxane (C₂H₆OSi, polydimethylsiloxane, PDMS), a non-toxic and safe two-component liquid silicone film, was finally selected as the substrate material for the sensor functional layer. Process data of the PDMS elongation rate change curve under gradually increasing uniaxial tensile force was tested, with the first column of data serving as the x-axis and the second column as the y-axis for plotting. Finally, an ultra-high elastic PDMS thin film substrate with an elongation at break ≥ 300% was obtained. This dataset serves as development process data, and the elasticity and recoverability of the substrate play a critical role in the stretchability of flexible sensors.
