This Small Business Innovation Research (SBIR) Phase I project will investigate the effect of carbon nanotubes on the photoconductivity of electroactive polymer matrix composites and on their performance and sensing efficiency. Several formulations of additives/polymer(s), including functionalized carbon nanotube systems, have potential to interact selectively, sensitively, and reversibly with trace analytes in the electroactive matrix. Nanotube-polymer sensing probes based on conductivity changes or mechanical force fluctuations exerted by the surrounding media, will be developed and tested for their sensitivity, reversibility, fast response to different analytes, and chemical and environmental stability. Superior formulations will be tested and compared to existing commercial sensing materials. Commercially, conventional metal oxide and polymer based sensors are usually impractical at ambient temperature due to low sensitivity. The combination of advanced conformal coating processes and advanced formulations of nanotube/polymers has the potential to alleviate the sensitivity and response to inorganic, organic, and biological analytes. These low cost ultra-light weight nanotube-polymer composite films with improved structural, stability and electrical properties will be important for portable sensor applications.

这项小型企业创新研究（SBIR）I阶段项目将研究碳纳米管对电活性聚合物基质复合材料的光电导率以及其性能和感知效率的影响。添加剂/聚合物（包括功能化的碳纳米管系统）的几种配方具有选择性，灵敏和可逆地与电活性基质中的痕量分析物进行相互作用的潜力。 基于电导率变化或周围培养基施加的机械力波动的纳米管聚合物传感探针，将开发并测试其灵敏度，可逆性，对不同分析物以及化学和环境稳定性的快速响应。将测试卓越的配方并将其与现有的商业传感材料进行比较。 在商业上，由于低灵敏度，在环境温度下，常规金属氧化物和聚合物传感器通常是不切实际的。纳米管/聚合物的晚期保形涂层过程和晚期制剂的组合有可能减轻对无机，有机和生物学分析物的敏感性和反应。 这些低成本的超轻质纳米管 - 聚合物复合膜具有改进的结构，稳定性和电性能对于便携式传感器应用至关重要。
