Embodiment 1
[0019] The first step is to select a fresh canna leaf, wash off the dust on the surface of the fresh canna leaf with tap water, and cut it into a size of 15cm long and 10cm wide as the original template;
[0020] In the second step, the canna leaf after cleaning is placed in a pouring mold corresponding to the length and width of the canna leaf, and the height of the pouring mold is 2cm;
[0021] The third step is to mix polydimethylsiloxane prepolymer, ethyl orthosilicate, and dibutyltin dilaurate in a ratio of 100:4:1 and stir for 20 minutes, then place it in a vacuum box The air bubbles in the mixture are drawn out, and then the mixture composed of polydimethylsiloxane prepolymer, tetraethyl orthosilicate, and dibutyltin dilaurate is poured on the fresh canna leaves in the mold and placed in the room temperature atmosphere. Curing for 24 hours to obtain a polydimethylsiloxane template, and then gently peel off the polydimethylsiloxane template from the canna leaf;
