Optical fibers with polyimide coatings for medical applications

Key properties of polyimide-coated optical fibers, unaged and exposed to various harsh environments, were investigated. The main intent was to model extreme conditions that can be encountered in medical applications of the fibers. A fiber designed by OFS showed good strength and was able to withstand exposure to extreme heat and humidity, multiple autoclave cycles, extended water soak and immersion in organic solvents. Similar fibers offered by other suppliers displayed shortcomings in some of the tested properties.

“…These magnitudes, although reasonable, are at the lower side of the distribution of data documented for polyimide-coated optical fibers. [8][9][10][11] Explanatory factors may include core and cladding dimensions, glass composition, coating thickness and quality, strain rate and humidity during testing.…”

“…There are reports of its ability to retain the hydroxyl groups from the water molecules, (Berger et al, 2003;Méndez et al, 2007;El Abdi et al, 2010;André et al, 2011), but also of the diffusion of other ions in addition to the ones from water. Such ions diffusion can be responsible for the optical fiber degradation and the decrease of its strength (Thirtha et al, 2002;Lindholm et al, 2004). Therefore, the behavior of the fiber strength with aging is not only dependent on the moisture present in the environment but also on the diffusion rate of the ions across the coating (Armstrong et al, 1999;Domingues et al, 2010).…”

“…The degradation of the silica fiber strength in distilled water is monitored by increasing surface roughness due to the dissolution of silica on the surface of the fiber by water corrosion [19,32]. When a water polar species ruptures the siliconeoxygen bond, dissolution occurs controlled by the following equation:…”

International audienceFiber-optic sensors are mostly used for in situ measurements of diverse chemical composition of industrial surfactants employed in industry as detergents, emulsifying and dispersing agents, coatings, and pharmaceutical adjuvants. These optical sensors are often used in wet chemical environments in which the temperature can be high. The purpose of this work is to study the mechanical behavior of optical fibers in contact with CetylTrimethylAmmonium Chloride in aqueous solution (CTAC) at different immersion durations and different temperatures. Result analysis demonstrates that immersion in CTAC drastically decreases the fiber strength particularly when immersed for long aging periods at high temperatures. Based on the analysis of aged fiber surface morphology obtained from Scanning Electron Microscopy, the extent of the damage of the fiber core and polymer coatings was observed
