Scalable Fabrication of Carbon/Elastomer Composite Electrodes and Piezoresistive Sensors

主讲人 : 孙力

Carbon nanomaterials have attracted extensive research and application interests since 1980s. Highlighted by the 1996 Noble Prize in Chemistry and the 2010 Noble Prize in Physics, carbon  d structures maybe the most studied and hypered nanomaterials in recent years. Currently, there are a number of producers capable of producing carbon nanomaterials on the order of hundreds tons/per year, but there still exists a tremendous gap of mass application of these materials due to the difficulties of nanomaterials handling and manipulation, which normally lead to poor quality control, low reproducibility, environmental sensitivity and also high cost. We think it maybe more realistic to develop applications utilizing the average effects of a large number of nanoentities instead of addressing the performances of individual or a small assembly of nanomaterials. We will show that carbon-polymer nanocomposites can have improved electromagnetic field shielding and static discharge characteristics together with improved vibration damping and noise reduction properties. Recently we are also developing high performance stretchable transparent electrodes and bi-  carbon sponge/composite piezoresitive sensors through improving device design and processing control. We want to demonstrate that combining functional nanomaterials with polymers can lead to the realization of novel sensing, actuating, wearable, energy and biomedical devices with various artificial physiochemical characteristics. Through these examples, we want to show the great potential and importance of designing non-traditional nanostructures and developing non-conventional nanomanufacturing techniques.
