Description
Technical field
The invention belongs to fluorescence detection fields, and in particular to a kind of to detect hypochlorous polyester film and preparation method thereof.
Background technique
There is simple and convenient, low in cost, the advantages that effect is obvious using fluorescent method detection substance.But this side
Method generally requires solution system and provides detection environment for it, and which has limited further applying for it.Polyester film is as a kind of high score
Sub- plastic film has the excellent performances such as good wrinkle resistance, conformality, heat resistance, translucency, chemical stability, intensity, makes
It can be used as good carbon dots carrier.By the way that carbon dots are coated on polyester film surface, detection hypochlorite can be realized
Function.
Summary of the invention
The purpose of the present invention is to provide a kind of hypochlorous polyester films of detection and preparation method thereof.
The present invention to achieve the above object, using following technical scheme:
A kind of preparation method detecting hypochlorous polyester film, includes the following steps:
1) citric acid and diethylenetriamine obtain the blue-fluorescence carbon dots solution for being able to detect hypochlorite by hydro-thermal method；
2) polyester film is fixed on the roller of dye jigger, is the fluorescent carbon point solution of step 1) preparation in dye gigging pond, dye
Temperature in material pond is 90-130 DEG C, dyeing time 40-60min, is dried after polyester film dyeing, then by rinsing, rinsing
Water temperature is 30-50 DEG C, and finally drying forms the functionalized polyester film with carbon dots coating.
The polyester film is polyethylene terephthalate film.
The specific steps of step 1) are as follows: citric acid and diethylenetriamine are dissolved in water, mixed liquor is formed；Then it will mix
It closes liquid to be transferred in hydro-thermal autoclave, is put into Muffle furnace later and heats 5h at 200 DEG C；After the reaction was completed, to reaction kettle
It is cooled to room temperature back spin and moisture is evaporated off, dialysis obtains fluorescent carbon point solution in ethanol solution later；
The ratio between described molal weight of citric acid and diethylenetriamine is 1-3:3.
The specification of bag filter is MW=3500Da.
The application further includes a kind of hypochlorous polyester film of detection, is obtained using the preparation method.
Compared with prior art, the beneficial effects of the present invention are:
The present invention obtains a kind of functionalized polyester film for being able to detect hypochlorite by the combination of carbon dots and polyester film,
And then miniaturization of the realization to hypochlorite, light-weighted easy detection.Its principle is that carbon dots are coated on polyester film surface, in purple
It is observed that polyester film issues blue-fluorescence under outer lamp.The polyester film of functionalization is immersed in the solution system of hypochlorite
In, then take and observe then blue-fluorescence disappearance under ultraviolet lamp.
Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, implement below with reference to best
The present invention is described in further detail for example.
