Problems solved by technology

However, the piezoelectric performance of the transparent piezoelectric film is relatively poor, and the light transmission is not good. Orienting the filling phase is an effective method to improve its piezoelectric performance and light transmission, such as Haixiong Tang et al. (see Advanced Energy Material , 2012, 2, 469–476) prepared PZT / PVDF (polyvinylidene fluoride) composite films with one-dimensional orientation of lead zirconate titanate (PZT) nanowires by uniaxial strain method, which has high piezoelectric coefficient along the direction of nanowire orientation For randomly oriented samples; Zeyan Wang et al. (see Materials Letters, 63, 2009, 130–132) used polyvinyl alcohol (PVA) to prepare one-dimensionally oriented zinc oxide nanowire arrays, which have high light transmittance ZnO samples with random orientation

Embodiment 1

[0041] The specific process of preparing a transparent film that can generate electricity is as follows:

[0042] (1) Weigh dimethyl siloxane, dimethyl siloxane curing agent and PZT nanorods obtained by electrospinning at a mass ratio of 10:1:1 and mix them evenly. This mixture is recorded as 3.

[0043] (2) Plating 10 nm chromium and 100 nm silver on one side of a clean glass slide by magnetron sputtering, and drawing copper wires with carbon paste.

[0044] (3) Take two pieces of above-mentioned glass slides as substrates, and stick a 150-micron-thick cover glass on both ends of one of them, which is recorded as 1; the other slide is not treated, and is recorded as 2.

[0045] (4) Take a certain amount of mixture 3 and pour it on sheet 1, place it in a vacuum environment to remove the air bubbles, then cover sheet 2 on sheet 1, and press hard to fill the space with mixture 3, and then place Air bubbles were removed in a vacuum environment. See attached figure 1 .

Embodiment 2

[0050] The specific process of preparing a transparent film that can generate electricity is as follows:

[0051] (1) Weigh dimethylsiloxane, dimethylsiloxane curing agent and PZT nanorods obtained by electrospinning at a mass ratio of 20:2:1 and mix them evenly. This mixture is recorded as 3.

[0052] (2) Take two pieces of clean ITO glass as substrates, stick a 150 micron thick cover glass on both ends of one of them, and record it as 1; leave the other piece untreated, record it as 2.

[0053] (3) Take a certain amount of mixture 3 and pour it on sheet 1, place it in a vacuum environment to remove the air bubbles, then cover sheet 2 on sheet 1, and press hard to fill the space with mixture 3, and then place Air bubbles were removed in a vacuum environment. See attached figure 1 .

[0054] (4) Connect the wires from 1 and 2 to 50 Hz, 220 V AC, let it stand for 24 hours, and then cut off the power supply. At this time, dimethylsiloxane polymerizes into polydimethylsiloxan...

Abstract

The invention relates to a transparent film capable of generating electricity and a preparing method thereof. The preparing method of the transparent film capable of generating electricity comprises the following steps that micro-nano materials with ferroelectricity are uniformly mixed with polymer monomers and curing agents of the polymer monomers for forming a mixture, then, the mixture is put between two parallel conducting base sheets, gas in the mixture is sufficiently removed, then, direct current electricity or alternating current electricity with certain frequency is added onto the two base sheets, meanwhile, the system is put into environment suitable for the polymer monomers to cure so that the complete curing is realized, a power supply is switched off, the cured mixture is peeled off from the base sheets, and the transparent film is obtained. The film is subjected to proper polarization processing, and the transparent film capable of generating electricity is obtained. The preparing method of the transparent film capable of generating electricity is simple and convenient, and the obtained transparent film capable of generating electricity has the advantages that the light transmission performance is obviously changed when the observation angle is changed, so that the peep-proof capability is realized.

Description

technical field [0001] The invention relates to a transparent film and a preparation method thereof, in particular to a transparent film capable of generating electricity and a preparation method thereof. Background technique [0002] With the continuous consumption of non-renewable resources, the utilization of some renewable resources has gradually been paid attention to. Like solar energy, wind energy, etc., mechanical energy exists everywhere in the surrounding environment. A nanogenerator is a functional nano-device that converts mechanical energy into electrical energy. Its performance is directly related to the performance of the generator used. In addition, because its generator is important in the fields of pressure sensors, artificial skin and piezoelectric touch screens Therefore, nanogenerators have attracted much attention in recent years. The transparent nanogenerator is a very important kind of nanogenerator. Most of its power generators are composite films ...
