Abstract :
The paper shows plastic optical fiber of 960/1000 μm Core/Cladding as an optical waveguide by removing a portion of the cladding section of the fiber via chemical etching and then applying dip coating method to fabricate 0.0005 M Oxazine 170 per Chlorate on the bare core. It is then followed by a Poly Di-Methyl Siloxane (PDMS) layer to design an opto-chemical sensor, to be used in detection of pH-based contaminants in air and water. The thickness of PDMS layer varies between 130-145 μm and that of Oxazine layer varies between 20 - 25 μm. This paper also shows a novel moisture trapping technique, necessary to trap moisture within PDMS and Oxazine which results in proper detection of contaminants.
