Abstract
The invention relates to a photonic crystal used for oil detecting, in particular to an anti-opal structure membrane of an oil sensitivity material taken as an oil sensitivity material. The surface wetting quality of the used anti-opal structure membrane of the invention is super-lipophilic; the aperture of the anti-opal structure membrane is between 200 and 1000 nm; photonic band gaps distribute in the region of between 400 and 2000 nm. After the anti-opal structure membrane absorbs oil, color or glossiness is changed, which can be used for observing the existence of the oil by eyes or can be used for authenticating oil kind in order to realize rapid oil detecting. Furthermore, a reflection spectrum of the anti-opal structure membrane after absorbing the oil is measured through using an ultraviolet-visible-near-infrared spectrophotometer, which can accurately detect a refraction index of the absorbed oil and the oil kind. The photonic crystal used for oil detecting utilizes the anti-opal structure membrane to detect oil, thus the photonic crystal used for oil detecting has the advantages of convenience, rapidness and low cost.
Description
Technical field
The present invention relates to be applied to the photonic crystal that oil detects, particularly the inverse opal structural membrane of oily sensitive material is as oily sensitive material.
Background technology
Along with oil industry rapid development, oil and the petroleum products oily leakage accident in storage and pipeline transportation happens occasionally, and is a urgent problem to the detection of leakage of oil.Existing oily leakage detection method roughly is divided into two classes, promptly detects the inflammable gas that produces in the leakage of oil or directly detects leakage of oil liquid.Detect the inflammable gas that produces in the leakage of oil and normally utilize detector, as catalytic combustion type and semiconductor-type [(a) Lukowiak, A.; Et al.Thin Solid Films 2007,515,7005; (b) Waghulade, R.B.; Patil, P.P.; Pasricha, R.Talanta 2007,72, and 594], these detecting devices are the fax sense, introduce unsafe factors such as electric spark in measurement easily, and also are not suitable for for not volatile heavy oil.Directly the many employings of detection leakage of oil liquid as sensitive element, are transferred to correlation receiver with light or electric signal mode with the volume change that the high molecular polymer swelling produces to the high molecular polymer of oil swell, finish detection [(a) Buerck, J. to leakage of oil; Et al.J.Hazard.Mater.2003,102,13; (b) Ishaq, I.M.; Et al.Sens.Actuators B:Chem.2005,107,738], this system is because high molecular polymer is little to the selectivity of different oil, exist simultaneously from leakage of oil and need the regular hour problem, greatly limited the fast development of high molecular polymer as sensitive element to the high molecular polymer swelling.
Photonic crystal is a kind of new function material, and it is by the formed periodic structure of the regular arrangement of single dispersed latex grain refraction or diffraction to be taken place incident light to realize special regulation and control to light.Photonic crystal provides new thinking for the design and the preparation of novel sensor, as the sensitive material that will be prepared into periodic structure as sensor, under extraneous environmental change, periodic structure changes, change to the regulation and control of light are also corresponding, thereby realize the sensing of environmental parameter variation to external world.The sensing material of existing bibliographical information can be realized [(a) Asher, S.A. such as humidity, pH, sucrose, temperature, metallic ion, solvents; Et al.Nature 1997,389,829; (b) Blanford, C.F.; Schroden, R.C.; Al-Daous, M.; Stein, A.Adv.Mater.2001,13,26] sensing of environmental factor or the detection that material exists.In the existing patent documentation, have with the detection and the sensing device of photonic crystal as biological (200520013602.7), gas concentration (200620100419.5,200620100423.1), humidity (200510011677.6) etc.
Inverse opal structural membrane is a kind of of photonic crystal, its be in the colloidal crystal inside configuration by filled polymer or inorganic material etc., remove the colloidal crystal emulsion particle then and obtain, be commonly referred to the anti-phase film of counter opal structure, or inverse opal structural membrane [(a) Holtz, J.H.; Asher, S.A.Nature 1997,389, and 829; (b) Vlasov, Y.A.; Bo, X-Z.; Sturm, J.C.; Norris, D.J.Nature 2001,414, and 289; (c) Blanco, A.; Ozin, G.A.; Et al.Nature 2000,405,437].The preparation of inverse opal structural membrane material is usually according to the material difference of filling, be divided into metal, inorganic, organic and polymkeric substance inverse opal structural membrane, because metal and inorganic material quality are more crisp, that the inverse opal structural membrane that is formed by them exists is broken easily, with defectives such as the substrate adhesive force is low, cause its actual possibility of its application to be restricted (Stein, A.; Schroden, R.C.Curr.Opin.Solid.St.M 2001,5, and 553), and be that the inverse opal structural membrane of material preparation can well solve the problem that these defectives cause with the polymkeric substance, so the purposes of polymkeric substance inverse opal structural membrane causes people's extensive concern.
