The porous plastic optical fiber can transmit light on the whole body for a long distance and has high transmissivity, better softness and strong modeling capacity.
Description
Technical field
The invention belongs to the multimedia materials technical field of information communication, particularly relate to a kind of porous plastic optic fiber.
Background technology
Optical fiber chemical sensor (FOCS) is rise the eighties a kind of highly sensitive, can be continuously, the trace and the trace analysis technology of automatic telemetering.Because it has the incomparable advantage of electrochemical sensor and makes optical fiber chemical sensor have huge application potential.Since first optical fiber chemical sensor in 1980 is born, the probe designs of existing 80 multiple sensors is used for the test of materials such as inorganics, aromatic hydrocarbon, aliphatic hydrocarbon, alcohol, amine, organic acid, medicine, enzyme, the automatic control, remote sensing analysis, the environmental pollutant that have been successfully used to production process and chemical reaction are monitored and various inorganics and organic analysis etc. automatically, are exploration fields that is in development.
Scales by one or more chemical reagent being modified optical waveguide probe is the chemically modified Optochemical sensor.In the chemically modified Optochemical sensor, most important parts surely belongs to the reagent sensitive layer of modification, and it is undertaking the vital task that chemical information is changed into detectable optical signalling.Therefore, the sensitive layer of being modified should be attended by the variation of the optical signalling that is easy to discern when interacting with the analytic target selectivity.
Generally speaking, the responsive series of strata of reagent are fixed on the rigid support body with certain method by responsive reagent and form.Any supporting body material as the Optochemical sensor sensitive layer all more or less possess following function: (1) provides the rigid support of fixing responsive reagent by solvent action or grid effect, and responsive system is protected; (2) by the selective permeation function of some polymeric films, provide selectivity to analytic target; (3) effect that performance obstruct stray light (natural light) or anti-(loosing) are penetrated flashlight in whole optical measurement system.In reported in literature, supporting body material has hydrophilic polymers such as hydrophobic polymeric membrane such as polystyrene, polyvinyl chloride, polyethylene and Mierocrystalline cellulose, polyacrylic ester, polyacrylamide, polyoxyethylene glycol.Although conventional in recent years fiber optical chemistry sensor probe obtains some development, still have many critical problems anxious to be solved: its photosensitive indicator charge capacity of coating of (1) fibre-optical probe routine or film coating method is limited, poor reliability, and sensitivity can't improve.(2) indicator wash-out phenomenon is serious, and corresponding signal drifts about with the bleaching and the loss of indicator, greatly the stability and the work-ing life of influence probe.
