Pipes abstractThis SGER award supports the modeling, synthesis and testing of non-contact microsensors consisting of single walled carbon nanotubes suspended in hollow polyimide microspheres. Micro polarized Raman spectroscopy will be used to detect strain along the longitudinal axes of the single walled carbon nanotubes suspended within the wall of the microsphere and thereby determine overall microsphere deformation state. Correlation between Raman spectral results and microsphere deformation will be determined analytically as well as experimentally. Unique methods for synthesis of the of the polyimide microsphere developed earlier for high performance polyimide foams will be adapted to produce the microspheres in the range of 100 microns in diameter and containing single walled carbon nanotubes. Given the elevated temperature properties of the polyimide, the microspheres should withstand temperatures of 350 degrees Celsius. The material should have applications as a sensor material for pressure and temperature which can be interrogated optically.

该SGER奖支持由悬浮在空心聚酰亚胺微球中的单壁碳纳米管组成的非接触式微传感器的建模、合成和测试。微极化拉曼光谱将用于检测悬浮在微球壁内的单壁碳纳米管沿纵向轴的应变，从而确定微球的整体变形状态。拉曼光谱结果与微球变形之间的相关性将通过分析和实验来确定。先前为高性能聚酰亚胺泡沫而开发的聚酰亚胺微球的独特合成方法将适用于生产直径在100微米范围内且含有单壁碳纳米管的微球。考虑到聚酰亚胺的高温特性，微球应该能承受350摄氏度的高温。该材料应应用于压力和温度的传感器材料，可以进行光学询问。
