Principle of:
as shown in fig. 1, a preparation method of the multifunctional flexible film packaging material comprises the following specific implementation steps:
step 1: preparing polyvinylpyrrolidone powder (PVP-K90), honey (Z35020101), deionized water, a beaker, a glass rod, a disposable plastic culture dish, disposable gloves, tweezers and other materials.
Step 2: at normal temperature, polyvinylpyrrolidone powder (PVP-K90) and honey (Z35020101) are mixed according to the mass ratio of 2:1, and then deionized water (mhd=7g, mpvp-k90=14g, mhd=120 g) was added at about 6 times the total mass.
Step 3: the beaker is placed in a dust-free environment at normal temperature, and is stirred by a glass rod every 6 hours, so that polyvinylpyrrolidone powder (PVP-K90) and honey (Z35020101) are fully contacted and dissolved in water, and are kept stand for crosslinking.
Step 4: after about 24-48 hours, the polyvinylpyrrolidone powder (PVP-K90) and the honey (Z35020101) are completely dissolved, and then whether the polyvinylpyrrolidone powder is completely dissolved or not can be judged by eye observation.
Step 5: and standing the obtained solution for 6-12 h to enable various groups in the solution to fully contact and react, then dipping the colloid with a glass rod in a bottoming manner, and if the colloid uniformly flows down along with the removal of the glass rod, the liquid is uniform colloid at the moment, and the final solution is uniform colloid and light yellow, and is named as PHC (PVP Honey Combine) material.
Step 6: spreading 15g PHC colloid, pouring into disposable plastic culture dish, placing in dust-free dry environment, standing for about 24 hr until colloid is substantially coagulated (culture dish size is)。
Step 7: and (3) placing the disposable plastic culture dish with the sample into a forced air drying oven, and baking for 2 hours at 30 ℃ for 6-8 times intermittently after stopping 2 hours, so that no bubbles exist in the PHC film and the flatness of the surface is ensured.
Step 8: taking out the disposable plastic culture dish from the forced air drying oven, tearing off the PHC film by using tweezers, and if the PHC film cannot be taken out, continuously baking until the PHC film can be torn off, and finally obtaining the required PHC film. (wherein, the thicker the PHC film, the longer the time required.)
Step 9: the PHC film prepared was subjected to various performance characterizations, and specific data are shown in FIGS. 2-6.
As shown in FIG. 2, the data were obtained by measuring the uniaxial tensile test by Shimadzu AGS-X type tensile tester, the crosshead speed was set to 20mm min-1, the PHC film was 80mm long, 20mm wide and 0.35mm thick, and finally the PHC film was stretched approximately 30 times on the basis of the original length, which proves the high ductility of the PHC film.

As shown in fig. 4, the data were obtained by observing the adhesion of the PHC film printed with the liquid metal line on the skin for 4 hours, and the end result was that the skin was free from any discomfort, the position of the adhered PHC film was not significantly different from the surrounding skin after the PHC film was peeled off, and the peeled off PHC film had a structural texture corresponding to the skin, which demonstrated that the PHC film had better conformality and biocompatibility.
As shown in fig. 5, this data was obtained by completely cutting one side of the PHC film with an experimental scalpel, photographing with an optical microscope at 80% rh for 4 hours, from which it was found that the material healed visually after 60min, whereas in the next 3 hours, the broken portion was slowly repaired, and the finally healed PHC film was stretched approximately 25 times under the tensile test of fig. 2, which demonstrates the self-healing property of the PHC film.
This data was obtained by placing the PHC film in a sealed box, continuously humidified and maintained above 80% RH, using a Keithley digital multimeter, as can be seen from the figure, and maintained nonconductive for 60 minutes at high humidity, demonstrating the non-conductivity of the PHC film.
In summary, the invention has the advantages that the whole preparation process and the selected materials are green and economical, and the finally obtained multifunctional flexible film has excellent properties of transparent non-conductivity, high ductility, self-healing property, self-conformality, biocompatibility, recycling property and the like.
