The fragrance release amount test was performed on the fragrance release film devices of examples 1 to 4 according to the above test method, and the fragrance release amount results of the fragrance release film device of example 1 under 0V, +1v, -1V voltages are shown in fig. 3, fig. 4, and fig. 5, respectively; the fragrance release results of the fragrance release film devices of examples 2-3 at-1V voltages are shown in fig. 6 and 7, respectively; the results of the fragrance release film device of example 4 at-0.2V, -0.6V, +1v voltages are shown in figures 8, 9 and 10, respectively.
As can be seen from fig. 3 to 5, the odor releasing film device of example 1 has a release amount of about 7.3% when the essence is left for a long time under a voltage of 0V, and a longer time is required to achieve a larger release amount; at +1V voltage, the essence release amount is about 7.5% after 120 min; and under the voltage of-1V, the release amount of the essence is about 25% after 120min, the release amount is obviously improved, and the essence can be released quickly. Analysis of the principle shows that when negative voltage is applied to two ends of the electrode, the conductive component PEDOT/PSS of the gel odor material has negative charges, and the negative charges and essence generate repulsive force to accelerate the release of the essence; on the other hand, the essence itself forms some charge acting force (such as pi-pi stacking or hydrogen bonding) with the conductive component PEDOT/PSS, and the negative voltage is applied to weaken the charge acting force and accelerate the release of the essence.
As can be seen from fig. 6, the fragrance release film device of example 2 released about 40% of fragrance after 120min at-1V; as can be seen from fig. 7, the fragrance release film device of example 3 released about 31% of fragrance after 120min at-1V.
As can be seen from fig. 8-9, the fragrance release film device of example 4 had a fragrance release of about 31% at a voltage of-0.2V for 120 min; at a voltage of-0.6V, the perfume release amount is about 38%; the result shows that the release rate of the essence is different when different negative voltages are applied, so that the release rate of the essence can be regulated and controlled by controlling the applied voltages; as can be seen from fig. 10, the fragrance release film device of example 4 showed a fragrance release of 16% after 120min at +1v voltage. According to analysis of the principle, the odor release film device with the conductive component of graphene is added, and as essence is negatively charged in the gel odor material, when negative voltage is applied, electrostatic repulsion between the essence and the graphene can cause the accelerated release of the essence; when a positive voltage is applied, the electrostatic attraction of the essence and the graphene can slow down the release of the essence.
In summary, according to the odor release film device disclosed by the application, different voltages are applied between two conductive glass sheets through an external power supply, so that the release of odor can be regulated and controlled in multiple gears.
