The sensor’s most significant part is a polymer whose nature defines the sensor’s response. The search for a polymer must be subject to some chemical criteria such as sensitivity to gas,and viscosity,... and to optical criteria such as homogeneity, refraction index and so forth; which may be antagonistic. Therefore, this study requires dealing. Also, selectivity of the polymeric basis is highlighted by using the standardised distribution coefficient. https://www.biotech-asia.org/vol1no1/a-study-of-specific-polymers-for-detection-of-gas-by-optical-fiber-sensor/ Polymers; optical fiber sensor; Refractive index
