Ternary polypyrrole/prussian blue/TiO2 nanocomposite wrapped poly-methyl methacrylate fiber optic gas sensor to detect volatile gas analytes
Abstract
Ternary composite of PPy-PB-TiO2 was prepared by in situ chemical polymerization. Clad modified PPy-PB-TiO2 sensor was developed to sense volatile organic gases. PPy-PB-TiO2 showed enhanced sensitivity for acetone, ammonia and ethanol gasses. The fabricated PPy-PB-TiO2 sensor was found to be selective for ammonia gas.
