Description
Technical field
The present invention relates to new material and instruction class product scopes.
Background technology
Vaccine needs stringent cold chain to store transport in the process of circulation, otherwise can lead to deterioration failure, be inoculated with without 2
The vaccines of DEG C of -8 DEG C storage cold chain transportations, primary risk are invalid immune.Similar incidents cause needs freeze or chilled food or
Whether multiple correlation standard (DB31/T388-2007) has obtained extensive concern to drug in supply chain link.If consumer
It can know that single-piece need to freeze or whether refrigerated product in storage does not conform to specification as the shelf-life as reading the date of manufacture, undoubtedly
The confidence that consumer ensures the marketing quality can be enhanced, while can also avoid refrigerating box, the unequal generation of cabinet internal temperature
Accident.Therefore, completely it is necessary to develop can detect label storage, transportation environment new technology, fundamentally solve cold
The supervision problem of chain storage.
The existing market prior art can be divided into electrical type technology and non-electronics major technology, electrical type technology (such as RFID skills
Art) can record temperature change, but because its volume it is big, it is expensive, need power supply so that it is only applicable to FCL and whole cabinet
Article is not used to Individual Items.And after existing non-electronics major temperature label is generally based on matrix melted by heat at present,
The chemical substance being mixed therein reacts with dyestuff generates color change to indicate temperature.Its major defect includes：1)
It is expensive；2) dyestuff used in or chemicals are toxic；3) specific temperature, narrow application range are only capable of displaying；4) mechanical property
It can poor, cracky.And there is also its deficiencies for patent (200420078916.0 Cold chain label)：1) it is only capable of in label equipped with liquid
It is disposed vertically, cannot be distinguished whether be detached from cold chain if tilt condition is met；2) temperature sensing material be ethyl alcohol, temperature-responsive property list
One, it is only capable of judging whether to be more than a certain temperature spot.
In conclusion the existing small-sized cold chain temperature label of non-electronics major still has many deficiencies.Market is for that can pacify
Entirely, inexpensively, accurately whether the label of overtemperature proposes urgent demand to display sole product.The present invention is temperature sensitive using metasable state
Type photonic crystal nanometer material senses the variation of storage, transportation environment temperature, technically realizes visualization instruction.
Invention content
The application is directed to the deficiency of Cold chain label existing goods, proposes using metasable state temperature sensitive type photonic crystal as core
Core material prepares cold chain storage and transportation monitoring label to design.Using metasable state photon crystal structure is formed under specific condition, present
Go out unique schemochrome.In low temperature environment, which can be stabilized, and color is always maintained at.Work as ring
During the temperature raising of border, which occurs destructive variation, and so as to lose color, sample is reentered into low temperature environment, Wu Fazai
Secondary to form original photon crystal structure, the color of sample cannot be restored (as shown in Figure 1).Therefore, which can realize temperature
Degree sensitivity is irreversibly changed instruction.In addition, it by the parameter such as nano particle shape of photonic crystal, nanoparticle size, receives
The optimization of formula of liquid etc. is modified and stablized to rice grain surface nature, and to can be achieved performance adjustable, so as to be needed towards different application
It asks：Different color change intervals (e.g., blue, green to red), the speed of response (such as second grade, minute grade, hour grade), response section
The cold chain storage colour-change indicator of (such as -50~20 degrees Celsius) performance.
The advantages of the application：
1. high sensitivity:When variation of ambient temperature reaches certain time, such as from less than the 8 DEG C (guarantors of most of vaccine
Deposit temperature range) 8 DEG C or more are changed to, which can delicately change color, and whether instruction vaccine is detached from cold chain.
2. high reliability：When indicating below temperature, the color of the label does not change environment temperature.Environment temperature
Higher, drug, food spoilage speed are faster, and label discoloration is corresponding to be accelerated, and can be adapted for varying environment temperature change.Therefore
The color change of label is with needing refrigerated product quality specifically good correlation.
3. high antifalsification：On the one hand, under the environment more than transition point, irreversible variation occurs for label color, again
The environment less than transition point is placed into, the color of label can not reply, therefore can effectively judge any from dispatching from the factory to using
Whether link is detached from cold chain.On the other hand, the chromogenic mechanism of the label is based on novel intelligent nanocomposite optical material, belongs to state
Border study frontier, technical threshold are high, it is difficult to be imitated by criminal.
4. highly integrated property：The indicator can be designed to the different shapes such as liquid, macromolecule membrane, easily paste or
Person is sprayed on commodity surface, does not influence the production, transport and storage of commodity.
Description of the drawings
The temperature sensitive intelligent color-changing indicator principle schematics of Fig. 1
In Fig. 2 embodiments, sample at normal temperatures colour fading variation (corresponded to from a to f the time be 0 respectively, 3,12,20,30,
60 minutes, scale was one centimetre)
Fig. 3 is the transmission electron microscope picture of photonic crystal particle in embodiment
Specific embodiment
Embodiment
Embodiment shows the implementation processes that one of which metasable state photonic crystal is used for label.The temperature sensitive set of tags
As photonic crystal nano particle volume fraction 10%, water volume fraction 50% and diethylene glycol volume fraction 40%.Outside
Add under special magnetic field and cryogenic conditions (3~5 degrees Celsius) formation patterns, such as Fig. 1 processes a；Figuratum label will be formed to put
It is placed in 5 degrees Celsius of refrigerators, does not observe apparent color change (Fig. 1 processes b) within experimental period；The temperature sensing material matches
When more than 8 degrees Celsius, since temperature raises, liquid fluidity improves, it is impossible to original photon crystal structure is maintained, so as to
Color and pattern gradually change until disappear (Fig. 1 process c), here we by label taking-up be placed in room temperature (20 degrees Celsius),
Its as shown in Figure 2 color from blue, to blue-green, green, yellow green, yellow and it is orange change successively, correspond to the time point
It is not an exposure to 0 in room temperature, 3,12,20,30,60 minutes.It is put into refrigerator in label is put at any time, color will not
Restore au bleu (Fig. 1 processes d).It can determine whether to be detached from the cold chain time from color, in addition, institute's Exposure Temperature is higher, color change
