The present invention relates to polydiacetylene, and more particularly to a hydrochromic polydiacetylene polymer patch.

Polydiacetylene is a polymer of diacetylene monomers, and is a conjugated polymer having characteristics that are produced through photopolymerization such as ultraviolet or gamma irradiation when the diacetylene monomers are arranged through self-assembly. . Such polydiacetylenes have alternating double and triple bonds in the polymer main chain, and generally have a maximum absorption wavelength at about 640 nm, which is blue, and exhibits external conditions (heat, solvent, pH, force, molecular recognition, etc.). As a result, the maximum absorption wavelength shifts to about 540 nm and turns red. Various kinds of sensors have been researched and developed by using the discoloration feature of the polydiacetylene.

Polydiacetylene  Containing polymer patches Water discoloration  reaction

Referring back to FIG. 1, when moisture is applied to the polydiacetylene-containing polymer patch (B), the polydiacetylene in contact with moisture is geometrically deformed to exhibit a reddish color through π-conjugated main chain structure breakdown. (C). In other words, it may show a hydrochromic reaction. Specifically, in case of contact with moisture, polydiacetylene has a maximum absorption wavelength of about 490 to about 590 nm, specifically, 520 to about 570 nm, for example, blue shifted to 540 nm. Can change. At the same time, the hydrochromic polydiacetylene may generate fluorescence. Accordingly, the polymer patch (B) containing the polydiacetylene may also be referred to as a hydrochromic patch.

This water discoloration is supposed to form voids as the diacetylene monomer which remained as a monomer without forming a polymer is dissolved in water, and this causes polydiacetylene to exhibit geometric deformation, but is not limited to this theory.

As described above, the polydiacetylene-containing polymer patch (B) exhibits a color change by contact with moisture (liquid or gas), and thus, may function sufficiently as a moisture sensor, specifically, a hydrochromic patch. Specifically, humidity may be sensed using the hydrochromic patch, or moisture in an organic solvent may be sensed. Further, the hydrochromic patch may be discolored from blue to red even by a very small amount of water (nano litres) coming out of the pores, and thus may be used as a fingerprint recognition application or a pores mapping paper. Specifically, it is possible to effectively map the pores of the entire body area, such as palms, soles, back, face, as well as fingers, thereby expanding the application field of the existing technology. In this way, it is possible to analyze the biological information such as the distribution of the pores of the body, it can be used in the medical field, beauty field, or criminal investigation field. Specifically, it may be used in the medical field, such as active pores distribution analysis or analysis of age-specific pores activity of hyperhidrosis patients, the cosmetic field for the development of deodorant or sweat inhibitors, and the field of criminal investigation through analysis of the pores map of fingerprints. In addition, the elution position can be accurately identified through color or fluorescence changes in response to moisture eluted from various water pipes, microcracked buildings, and experimental equipment, and thus can be widely used for commercial purposes. In addition, the polymer patch (B) can produce not only hard hydrochromic patches, but also improved hydrochromic patches with improved ductility, by adjusting the physical properties of the matrix polymer. It can be usefully used for detecting moisture of the skin.

Fig. 2 is a photograph of a PEO film (a) containing DA-Im obtained according to Hydrochromic patch Preparation Example 1-1b and a PEO film (b) containing PDA-Im obtained by light irradiation on the film.

Referring to FIG. 2, the PEO film (a) containing DA-Im was a film containing DA-Im and PEO in a weight ratio of 1: 2.5 and having a colorless opaque thickness of about 10 μm. On the other hand, the film (b) irradiated with UV showed blue color. The blue color may mean that diacetylene (DA-Im) is polymerized to form polydiacetylene (PDA-Im). In addition, it can be seen that both the PEO film (a) containing DA-Im and the PEO film (b) containing PDA-Im are flexible films and do not produce visible cracks by bending.

FIG. 3 is a graph showing Raman spectra of a PEO film containing DA-Im obtained according to Preparation Example 1-1b and a PEO film containing PDA-Im obtained by light irradiation of the film.

Referring to FIG. 3, the PEO film (PEO + PDA) containing PDA-Im compared with the PEO film itself (PEO) and the PEO film (PEO + DA) containing DA-Im conjugated with a 1453 cm −1 peak representing the conjugated alkenes. It can be seen that the 2080 cm -1 peak representing the gated alkyne is characteristically represented. From this, it can be seen that the polydiacetylene in the PEO film containing PDA-Im has a highly π-conjugated backbone by alternating double bonds and triple bonds.

4 is a) photograph, b) backbone modification of polydiacetylene, c) UV-vis absorption spectrum, before and after adding water to a PEO film containing PDA-Im obtained according to Preparation Example 1-1b of hydrochromic patch. And d) Raman spectrum.

Referring to FIG. 4, the PEO film containing PDA-Im obtained according to Hydrochromic patch Preparation Example 1-1b shows water-promoted blue-to-red color change by water (a) After the moisture had dried, it did not return to blue again. On the other hand, in the UV-vis absorption spectrum, the maximum absorption wavelength before exposure to moisture is about 636 nm, the maximum absorption wavelength is shifted to about 537 nm after exposure to moisture (c). In addition, the Raman spectrum shows that the 2080 and 1453 cm -1 bands corresponding to the alkyne-alkene bands were shifted to 2120 and 1515 cm -1 bands, respectively, after hydration compared to before hydration. Can be. These results may mean that the distortion occurs in the main chain of the polydiacetylene due to moisture, so that some distortion is generated in the superposition of the π-orbital array (b).

<Sweat pore mapping example>

The degree of mapping of the pores was observed by gently contacting the fingertips on the PEO film containing PDA-Im obtained in Preparation Example 1-1b.

FIG. 5 is a photograph showing an optical image after a finger is touched on a PEO film containing PDA-Im obtained according to hydrochromic patch Preparation Examples 1-1a to 1-1f. Fluorescence microdots showing sweat-secreting active pores were analyzed using a fluorescence spectrometer (510-550 nm excitation).

Referring to FIG. 5, a red fluorescence image expressed by sweat at the pore position may be confirmed. This is evident throughout the PEO films containing PDA-Im formed using PEOs with different molecular weights of 100K to 4000K. From this it can be seen that it is possible to implement a flexible yet moisture-sensitive hydrochromic patch irrespective of the molecular weight of the matrix polymer. However, when a low molecular weight (eg 100 K) matrix polymer is used, there may be a slight possibility that the hydrochromic film is torn, and when a high molecular weight (eg 300 K or more) matrix polymer is used, Due to the viscosity, there may be some difficulties in obtaining a film of uniform thickness.

FIG. 6 is a photograph showing an optical image after contacting the nose, the entire palm, and the sole of the foot on a PEO film containing PDA-Im obtained in Preparation Example 1-1b. Fluorescence microdots showing sweat-secreting active pores were analyzed using a fluorescence spectrometer.

Referring to FIG. 6, the PEO film containing PDA-Im may be in contact with the nostril (a), the entire palm (b) including the depression (d) of the palm, and the depression (c) of the sole. In addition, its flexibility allows almost perfect contact with the curved parts of the human body, greatly improving the pores mapping efficiency.

Figure 7 is a photograph showing the degree of water discoloration according to the relative humidity of the PEO film containing PDA-Im obtained according to the hydrochromic patch Preparation Example 1-1b. Specifically, it shows the degree of water discoloration in a state exposed for 5 minutes at a specific relative humidity.

Referring to FIG. 7, the PEO film containing PDA-Im obtained according to the hydrochromic patch Preparation Example 1-1b did not discolor even when exposed for 5 minutes at a relative humidity of 20 to 95%. However, when exposed to 100% relative humidity, it immediately turned red. From this, it can be seen that the hydrochromic patch according to the present embodiment is hydrochromic only when directly exposed to water without being greatly affected by the humidity of the surrounding environment.

8 is a photograph (a) of a polymer film containing PDA-Im obtained according to hydrochromic patch preparation examples 1-1b, 1-2, 1-3, and 1-4, and an optical image after contact with a finger (b ), And a fluorescence microscope image (c).

Referring to FIG. 8, when PEO, PMMA, PS, and PVC are used as the matrix polymer, all of them show a blue film, indicating that DA-Im is polymerized by UV to form PDA-Im. This may mean that DA-Im may self-assemble in the polymers. In addition, when PS and PVC were used as the matrix polymer, it was observed that cracking or cracking occurred when a bending force was applied, but there was no problem in indicating water discoloration.

On the other hand, when PEO is used as the matrix polymer when the finger is in contact with the polymer film containing PDA-Im, finger fingerprints including pores appear clearly in both optical and fluorescence microscope images, whereas PMMA and Slight pores were observed with PVC and no pores with PS. This was estimated according to the degree of hydrophilicity of the matrix polymer. In other words, PS is a very hydrophobic polymer, and PMMA and PVC are also known as hydrophobic polymers.

9 is a photograph of a polymer film containing PDA-Cs obtained according to the hydrochromic patches Preparation Examples 2-1 to 2-4.

Referring to FIG. 9, when PEO, PVP, PVA, and PVC are used as the matrix polymer, all of them show a blue film, and it can be seen that DA-Cs is polymerized by UV to form PDA-Cs. This may mean that DA-Cs can be self-assembled in the polymers. In addition, in all cases, flexibility was excellent, such as no bending or cracking when bending force was applied.

10 is a photograph showing the degree of water discoloration according to the relative humidity of the polymer film containing the PDA-Cs obtained according to the hydrochromic patch Preparation Examples 3-1 to 3-4. Specifically, it shows the degree of water discoloration in a state exposed for 5 minutes at a specific relative humidity.

Referring to FIG. 10, it can be seen that as the content of PEG having hydrophilicity and hygroscopicity is increased in the state of using PVP as the matrix polymer, the relative humidity value in which water discoloration occurs is reduced. Specifically, when 0.05 ml of PEG and 0.10 ml were added, water discoloration began to appear at 70% RH, and when 0.15 ml of PEG appeared to start at water discoloration at 60% RH. When 0.20 ml of Hg added, water discoloration began to appear at 50% RH.

In the above, the present invention has been described in detail with reference to preferred embodiments, but the present invention is not limited to the above embodiments, and various modifications and changes by those skilled in the art within the spirit and scope of the present invention. This is possible.
