Thinner is Better: An Ultrathin Conducting Oligoaniline Film for Gas Microsensors with Ultralow Detection Limits.


An ultralow-limit gas microsensor based on an ultrathin conducting oligoaniline film integrated with microscale gold electrodes is developed. A nanoscale oligoaniline film is fabricated on a poly(dimethylsiloxane) (PDMS) substrate using graft polymerization using FeCl(3) , a mild oxidant, rather than conventional (NH(4) )(2) S(2) O(8) . The as-fabricated… (More)
