Abstract Details

2019, MS, University of Cincinnati, Engineering and Applied Science: Materials Science.
In this thesis, a scalable way of fabricating a freestanding, hydrogen gas-sensitive material from CNTs and palladium is discussed. CNT sheets were fashioned from spinnable CNT arrays and palladium was deposited on this structure via a combination of electroless deposition and a modified “brush” electrochemical plating method. The material possessed a Limit of Detection of 0.1%mol hydrogen with reversibility. The sample lost reversibility after repeated exposure, however re-densification with ethanol alleviated this issue. The durability of the sample was demonstrated by integration into a RipstopTM polyester-blend fabric. The fabric-integrated sensor maintained sensitivity but lost its signal reversibility. The material was further characterized via scanning electron microscopy, energy-dispersive x-ray spectroscopy, thermogravimetric analysis, and x-ray diffraction.
